The federal government has recognized 573 Indian tribes as distinct, independent political communities with tribal sovereignty. There are different categories of tribal lands, with differing implications with respect to ownership and administration. Reservations are defined geographic areas with established boundaries recognized by the United States. Tribal lands vary in size, demographics, and location. For example, those lands smallest in size are less than one square mile, and the largest, the Navajo Nation, is more than 24,000 square miles (the size of West Virginia). Tribal land locations can range from extremely remote, rural locations to urban areas. Figure 1 shows tribal lands in the United States according to the 2010 Census. The term “broadband” commonly refers to Internet access that is high speed and provides an “always-on” connection, so users do not have to reestablish a connection each time they access the Internet. Broadband service may be “fixed”—that is, providing service to a single location, such as a customer’s home—or “mobile,” that is, providing service wherever a customer has access to a mobile wireless network, including while on the move, through a mobile device, such as a smartphone. Fixed and mobile broadband providers deploy and maintain infrastructure to connect consumers to the Internet. Providers offer fixed Internet service through a number of technologies, such as copper phone lines, fiber-optic lines, coaxial cables, wireless antennas, satellites, or a mix of technologies (see fig. 2). To install fixed or wireless infrastructure, providers must obtain permits from government entities with jurisdiction over the land or permission from public utilities to deploy infrastructure on existing utility poles. The federal government has emphasized the importance of ensuring Americans have access to broadband, and a number of agencies, including FCC, currently provide funding to subsidize broadband deployment in areas in which the return on investment has not attracted private investment. The Communications Act of 1934, as amended by the Telecommunications Act of 1996, specifies that consumers in “rural, insular, and high-cost areas” should have access to telecommunication services and rates that are “reasonably comparable” to consumers in urban areas. To achieve this goal, FCC administers the High-Cost program, which provides subsidies to providers of phone service in rural, insular, and other remote areas. In 2011, FCC launched a series of reforms to its High-Cost program, including adding support for broadband services, and created the Connect America Fund, which provides subsidies to fixed and mobile providers of telecommunications and broadband services in rural, insular, and other remote areas where the costs of providing service is high. To be eligible for Universal Service Fund support from FCC, a provider must be designated an Eligible Telecommunications Carrier by the appropriate state or by FCC and must meet certain service obligations. The Connect America Fund has distributed approximately $4.5 billion per year, and has separate funding mechanisms targeted to specific goals. For example, there are funds for fixed-phone and broadband service and funds for mobile service, including a Tribal Mobility Fund (Phase 1) that awarded nearly $50 million in 2014 for the provision of 3G and 4G service to unserved tribal areas. In addition to FCC, a number of other agencies provide funding for broadband deployment in unserved or underserved areas. For example, the United States Department of Agriculture’s Community Connect Program, which provides grants to rural communities to provide high- speed Internet service to unserved areas. The American Recovery and Reinvestment Act of 2009 (Recovery Act) mandated the development of a nationwide map of broadband availability. To implement the act, the National Telecommunications & Information Administration (NTIA)—an agency within the Department of Commerce—established a grant program to enable U.S. states and territories to collect state-level broadband mapping data. NTIA used these data to launch the National Broadband Map (www.broadbandmap.gov) in February 2011. As the funding for the NTIA’s program came to an end in 2014, NTIA stopped collecting data to update the map and, according to FCC officials, created a memorandum of understanding with FCC through which FCC agreed to maintain public access to the last version of the map. FCC issued rules in 2013 to begin collecting broadband deployment data, in addition to the broadband subscription data it had collected from providers since 2000. FCC sought, but did not receive, $3 million to update the National Broadband Map in its fiscal year 2015 and fiscal year 2016 budgets. In 2018, Congress directed FCC to develop a report by March 23, 2019, evaluating broadband coverage in certain tribal lands (to include an assessment of areas that have adequate broadband coverage, as well as an assessment of unserved areas), and to complete a proceeding to address unserved areas by September 23, 2020. Currently, FCC requires broadband providers to report on their broadband deployment by filing a form twice a year (Form 477). Fixed broadband providers submit a list of the census blocks in which their broadband service is available, and mobile providers submit “shapefiles”—a geospatial depiction of the coverage area, which FCC refers to as “polygons”—of their coverage areas. FCC uses providers’ 477 data to develop a statutorily mandated annual report on advanced telecommunications capability. In addition, in 2016, FCC began publishing its own maps of broadband deployment, using the information from providers’ Form 477 filings. In February 2018, FCC launched an updated map of fixed broadband deployment (https://broadbandmap.fcc.gov/#/). This map allows users to search for broadband deployment by address and provides summary-level statistics regarding broadband deployment in specific tribal lands (see fig. 3). According to FCC officials, this new map format will support more frequent data updates. FCC also provides national maps of mobile LTE coverage; these maps do not allow users to access data at the same level of granularity as the maps of fixed broadband (see fig. 4). FCC collects and uses data that capture broadband availability to measure broadband access on tribal lands, leading to overstatements of broadband access on tribal lands. Specifically, FCC’s method of collecting mobile and fixed broadband data from providers (the Form 477) does not accurately or completely capture broadband access on tribal lands because it (1) captures nationwide broadband availability data— areas where providers may have broadband infrastructure—but does so in a way that leads to overstatements of availability, and (2) does not capture information on factors that FCC and tribal stakeholders have stated can affect broadband access on tribal lands, such as affordability, service quality, and denials of service. Nonetheless, FCC uses its Form 477 broadband availability data in annual broadband deployment reports to measure the percentage of Americans living on tribal lands with or without access to broadband, and to measure progress toward FCC’s strategic goal of increasing all Americans’ access to affordable broadband. By using broadband availability data to measure broadband access on tribal lands, FCC overstates broadband access on tribal lands. FCC’s Form 477, its primary method of collecting nationwide broadband data, collects information on broadband availability, which identifies where providers have broadband infrastructure and could potentially provide broadband services but not where consumers can actually access those services. Moreover, the Form 477’s mobile broadband data- collection methods are not standardized, and its fixed broadband data- collection methods are not sufficiently granular to provide information about broadband availability on tribal lands. FCC’s Form 477 requires mobile broadband providers to report their coverage areas by submitting geospatial data depicting the areas in which consumers could expect to receive the minimum advertised speed. FCC has previously noted the importance of collecting nationally standardized, uniform broadband data from providers to assess broadband availability and allow for easy comparison across providers. However, the Form 477 does not require that providers use a standardized method with defined technical parameters (such as signal strength, or amount of interference) when determining their coverage area, resulting in data that cannot be meaningfully compared across providers, according to FCC. To map their coverage areas, providers may use predictive models based on different measurement methods and a variety of factors known to affect mobile broadband service such as topography, tree cover, and buildings, among other factors. Providers and tribal stakeholders have expressed concern with the accuracy of FCC’s mobile broadband data, and FCC has acknowledged concerns that the lack of a standardized method resulted in data that were unreliable for the purposes of determining mobile broadband coverage for specific geographic areas, such as tribal lands. About half of the tribal government representatives we interviewed told us that they believe FCC’s data overstate mobile LTE broadband availability on their lands. For example, a few representatives expressed concerns with the accuracy of the mobile data in areas with varied terrain, such as mountains and valleys. In comments to FCC, broadband providers have also raised concerns regarding the accuracy of the mobile coverage data generated by the Form 477 for the purposes of identifying areas eligible for funding through FCC’s Mobility Fund Phase II program, which provides federal funding to increase mobile broadband services in unserved areas. In 2017, in response to such concerns, FCC reversed its prior decision to use the Form 477 data to identify specific areas eligible for federal funding through the Mobility Fund Phase II program. Instead, FCC undertook a one-time special data collection, for which it required providers to measure their coverage based on a common set of standards, in order to better identify unserved areas that would be presumptively eligible for funding. FCC plans to allow parties, including tribal governments, to challenge the data where they believe the data overstate mobile broadband coverage through August, 2018. Additionally, in an August 2017 Notice of Proposed Rulemaking, FCC requested comment on potential changes to modernize its Form 477 data collection, including whether it should require all providers to use a standardized method when submitting mobile coverage data on the form. FCC officials told us that they do not have a timeline for the development of a final rule, and as of August 2018, FCC had not yet issued a final rule on modernizing the Form 477. The Form 477 collects fixed broadband data that are not sufficiently granular to accurately depict broadband availability on tribal lands. Specifically, FCC directs fixed broadband providers to submit a list of census blocks where service is available on the Form 477. FCC defines “available” as whether the provider does—or could, within a typical service interval or without an extraordinary commitment of resources— provide service to at least one end-user premises in a census block. Thus, in its annual reports and maps of fixed broadband service, FCC considers an entire block to be served if a provider reports that it does, or could offer, service to at least one household in the census block. FCC does not define a typical service interval or an extraordinary commitment of resources in its Form 477 instructions. However, FCC officials stated that providers should not report service in areas in which major construction would be required to provide service. A few providers told us that the lack of clear guidance from FCC regarding how to determine where broadband is available has led different providers to interpret the Form 477 directions in different ways, which can affect the accuracy and consistency of reporting from provider to provider. For example, in a filing with FCC, one provider stated that it had misapplied the definition of “available” and, as a result, overstated the availability of its services by almost 3,000 census blocks. As shown in figure 5, FCC’s definition of availability leads to overstatements of fixed broadband availability on tribal lands by: (1) counting an entire census block as served if only one location has broadband, and (2) allowing providers to report availability in blocks where they do not have any infrastructure connecting homes to their networks if the providers determine they could offer service to at least one household. Almost all the providers and private companies, and most of the representatives of tribal governments and organizations we spoke with told us that due to these issues, FCC’s definition of availability results in data that overstate broadband availability. According to FCC officials, FCC requires providers to report fixed broadband availability where they could provide service within a “typical service interval” and without “an extraordinary commitment of resources” in order to: (1) ensure that it captures instances in which a provider has a network nearby but has not installed the last connection to the homes, and (2) identify where service is connected to homes, but homes have not subscribed. FCC officials also told us that FCC measures availability at the census block level because sub-census block data may be costly to collect. In 2013, FCC considered collecting more granular nationwide data on broadband deployment but decided against collecting these data because it determined that the burden would outweigh the benefit. However, FCC, tribal stakeholders, and providers have noted that FCC’s approach leads to overstatements of availability. For example, in its 2017 Notice of Proposed Rulemaking on modernizing the Form 477 data collection, FCC acknowledged that by requiring a provider to report where it could provide service, it is impossible to tell whether the provider would be unable or unwilling to take on additional subscribers in a census block it lists as served. According to FCC, this limits the value of the data to inform FCC policies. In addition, several providers and tribal stakeholders we interviewed said that some “digital subscriber line” (DSL) and fixed wireless providers may overstate their service areas on the Form 477 because they may not take into account technological or terrain limitations that would affect their ability to actually provide service. FCC has also recognized that by measuring availability at the census block level, not every person will have access to broadband in a block that the data show as served, and FCC has noted that in rural areas, such as tribal lands, census blocks can be large and providers may only deploy service to a portion of the census block. A few representatives for tribal governments and organizations noted that the use of census blocks may uniquely overstate broadband availability on tribal lands when census blocks contain both tribal and non-tribal areas, because availability in the non-tribal portion of the block can result in the tribal area of the census block also being counted as served. FCC is considering requiring providers to report whether they are willing and able to serve additional customers in a census block and collecting sub-census block data in its 2017 proposed rulemaking on modernizing the Form 477. About one-third of the parties that commented on FCC’s proposals were not in favor of FCC collecting these more granular data on the Form 477, stating that the data would be less accurate and more burdensome for providers to collect and report, among other reasons, and questioned whether more detailed information on nationwide broadband availability is necessary. We heard similar concerns from a few of the providers and trade associations we interviewed. However, about one- third of the parties that commented on FCC’s proposals were in favor of collecting more granular data, stating that such data would be more useful for policymakers and more accurate. Additionally, a few tribally owned and non-tribal providers we interviewed told us that providers already maintain data for business purposes that would allow them to report more granular information on broadband availability. One stakeholder we spoke with pointed out that, as the federal government and states work to ensure the last remaining unserved areas—rural, low- population density areas including tribal lands—have service, sub- census-block-level data are needed to ensure that governments are making wise and accurate investments. FCC does not collect information on several factors that FCC and tribal stakeholders have stated can affect broadband access. FCC and tribal stakeholders have noted that broadband access can be affected by factors such as the affordability and quality of the broadband services being offered, and the extent to which providers deny service to those who request it. By collecting and using data on factors that can affect broadband access, FCC would have more complete information on the extent to which Americans living on tribal lands have access to broadband Internet services. Affordability: FCC has noted that affordability of broadband services can affect broadband access but does not collect information on the cost of broadband service on tribal lands on the Form 477. For example, in the National Broadband Plan, FCC cited affordable access to robust broadband service as a long-term goal, and in its Strategic Plan 2018–2022, FCC acknowledged that affordability is an important factor affecting broadband access and a key driver of the digital divide. Moreover, most of the representatives of tribal governments and organizations we spoke to told us that the affordability of broadband services is an important factor for understanding whether or not people on tribal lands could realistically access broadband services. Tribal government officials from one tribe we spoke with told us that residents on their lands cannot access broadband because it is too costly. For example, a provider that advertises services on the tribe’s land charges $130 per month for broadband services, approximately one-and-a-half times the average rate providers charge for comparable services in urban areas, according to FCC (see fig. 6). In the 2018 Broadband Deployment Report, FCC acknowledged that affordability can influence a consumer’s decision on whether to purchase broadband, but FCC did not consider cost in its assessment of broadband access on tribal lands, stating that pricing does not go to the congressional requirement to assess deployment and availability in conducting its inquiry as required by Congress under section 706 of the Telecommunications Act and also citing a lack of reliable comprehensive data on this issue. In addition, FCC officials we interviewed acknowledged that while broadband service may be technically available, it may be prohibitively expensive for some, which may make availability alone an incomplete indicator of broadband access. Quality of Service: In the Telecommunications Act of 1996 Congress recognized the importance of service quality by defining advanced telecommunications capability as any technology that enables users to originate and receive high-quality voice, data, graphics, and video telecommunications. In keeping with this legislation, FCC has consistently set thresholds for speeds that qualify as broadband services and has stated that “latency” and consistency of service figure prominently into whether a broadband service is able to provide advanced capabilities and thus whether users can access high-quality telecommunications. Likewise, almost all of the representatives for tribal governments or organizations we interviewed told us that quality of service is a key component of access to broadband and that routine outages, slow speeds, and high latency keep people on tribal lands from consistently accessing the Internet. Most tribal stakeholders and a few providers we interviewed told us that factors such as terrain, weather, and type of technology can all affect the quality of service an end user receives and, ultimately, the subscribers’ ability to access the Internet (see fig. 7). For example, some representatives of tribal governments and organizations told us issues like oversubscription— when a provider signs up more customers than its equipment can handle—and outdated or limited infrastructure result in low-quality services that cannot support advanced and, in some cases, basic functions. Though FCC uses the Form 477 to collect some data on advertised speeds from providers, FCC does not collect data on actual speeds, service outages, and latency on the form. In its 2018 Broadband Deployment Report, FCC stated that it did not consider FCC data on actual speed, latency, or consistency of service when evaluating broadband access due to the lack of appropriate data. FCC noted that the lack of Form 477 data on actual speeds in particular constrained evaluation of mobile broadband access. Service Denials: FCC has recognized that information on denials of service is pertinent to understanding actual broadband access but does not collect data on service denials in the Form 477. Specifically, in the National Broadband Plan, FCC recommended that FCC collect data to determine whether broadband service is being denied to potential residential customers based on the income of the residents in a particular geographic area. Some representatives of the tribal governments or organizations told us that that they were aware of a provider denying service to residents of tribal lands, despite the provider reporting broadband availability on at least a portion of those lands, according to our analysis of the Form 477 data. These representatives told us that they believed service was denied because of disputes with the tribal government, low demand for service, or the high costs of extending services to the home on tribal lands. Some representatives of tribal governments or organizations we spoke with also told us that providers may have denied service because their equipment was at capacity and could not accommodate new users (see fig. 8). For example, on three of the tribal lands we visited, we observed fiber optic cable located close to government and residential structures that did not have broadband access via fiber. According to tribal government officials, despite the physical proximity of the fiber optic cable, the tribal government and residents could not access it because the provider was not offering service or was unwilling or unable to build to the structures. A few providers we interviewed stated that they may not provide services to individuals who request them because of high-costs, administrative barriers, or technical limitations. However, FCC does not collect data on service denials on the Form 477. In its Strategic Plan 2018–2022 and the National Broadband Plan, FCC identified increasing all Americans’ access to affordable broadband as a long-term, strategic goal. Congress has similarly directed FCC to develop policies and programs aimed at increasing access to affordable broadband in all regions of the United States, including tribal lands, and required FCC to report annually on its progress. According to the Government Performance and Results Act (GPRA), as enhanced by the GPRA Modernization Act of 2010 (GPRAMA), agencies should use accurate and reliable data to measure progress toward achieving their goals. Additionally, Standards for Internal Control in the Federal Government state that agencies should use quality information— information that is complete, appropriate, and reliable—to inform decision-making processes and evaluate the agency’s performance in achieving goals. According to these standards, agencies should also communicate quality information externally to achieve the agency’s goals. However, FCC has used its Form 477 data, which do not accurately or completely measure broadband access on tribal lands, as its primary source to evaluate progress toward FCC’s strategic goal of increasing broadband access and to develop maps and reports intended to depict broadband access on tribal lands. For example, in its 2018 Broadband Deployment Report, FCC found that 64.6 percent of Americans residing on tribal lands have access to fixed broadband services. By using these data, FCC has overstated the extent to which Americans living on tribal lands can actually access broadband Internet services and FCC’s progress toward increasing broadband access. As a result, the digital divide may appear less significant as a national challenge, and FCC and tribal stakeholders working to target broadband funding to unserved or underserved tribal lands will be limited in their ability to make informed decisions. This increases the risk that residents living on tribal lands will continue to lack broadband access. Some tribal officials stated that inaccurate data have affected their ability to plan their own broadband networks and obtain federal broadband funding, and most of the tribal stakeholders we interviewed identified a pressing need for accurate data on the gaps in broadband access on tribal lands in order to ensure that tribes can qualify for federal funding and to effectively target the areas that need it most. For example, representatives for one tribal government that is providing broadband services said the government will not be able to use a federal grant to build broadband infrastructure in areas of their reservation that lack access, because the Form 477 data overstate actual access on the tribe’s land. As more than three quarters of the tribal governments we spoke to are working to provide broadband services on their lands in some capacity, overstating broadband access on tribal lands could affect the ability of a number of tribes to access federal funding to increase broadband access on their lands. As previously discussed, FCC is considering proposals to modify its Form 477 data collection as part of a 2017 Notice of Proposed Rulemaking, but FCC officials told us that the Commission does not have a timeline for issuance of a final rule. While some of FCC’s proposals could help address some of the limitations identified above by, for example, collecting more granular nationwide broadband availability data, FCC has not addressed specifically the collection of more accurate and complete data on broadband access for tribal lands in this proceeding. FCC has identified the need to improve broadband data for tribal lands in particular, and as previously noted, in 2018 Congress directed FCC to develop a report evaluating broadband coverage in certain tribal lands and initiate a proceeding to address the unserved areas identified in the report. FCC officials told us that FCC has not determined how it will address this requirement, but it is currently considering its options, including potentially addressing the requirement as part of its ongoing proposed rulemaking on modernizing the Form 477 data collection. An evaluation of broadband coverage on tribal lands that relies on the current Form 477 data would be subject to the limitations described above, including the overstatement of broadband access on tribal lands. Additionally, FCC has demonstrated that it is possible in some circumstances to collect more granular data when such data collection is targeted to a specific need or area. For example, in 2017 FCC began requiring certain providers that receive funding through the Connect America Fund to report the latitude and longitude of locations where broadband is available, and FCC has noted that these more granular data are extremely useful to the Commission, especially for rural areas where census blocks can be quite large. A few large providers and trade associations similarly stated in public comments on FCC’s proposed rulemaking to modernize the Form 477 process that FCC should target its collection of more granular broadband data to areas where the data are most likely to be overstated—specifically, large, rural census blocks with low population densities, such as those on tribal lands. Additionally, as discussed above, FCC undertook a one-time special data collection for Mobility Fund II to ensure that the mobile broadband data it collected would be reliable for the intended use. By developing and implementing methods for collecting and reporting accurate and complete data on broadband access specific to tribal lands, FCC would be able to better identify tribal areas without access to broadband and to target federal broadband funding to the tribal areas most in need. FCC uses data submitted by broadband providers via the Form 477 process to develop maps and datasets depicting broadband services nationwide, and in specific locations, such as tribal lands, but does not have a formal process to obtain input from tribes on the accuracy of the broadband data. FCC’s 2010 National Broadband Plan noted the need for the federal government to improve the quality of data regarding broadband on tribal lands and recommended that FCC work with tribes to ensure that any information collected is accurate and useful. It also noted that tribal representatives should have the opportunity to review mapping data about tribal lands and offer supplemental data or corrections. Similarly, federal internal control standards note the need for federal agencies to communicate with external entities, such as tribal governments, and to enable these entities to provide quality information to the agency that will help it achieve its objectives. FCC officials told us that they address questions and concerns regarding provider coverage claims submitted to the Office of Native Affairs and Policy, which will work with tribal governments to help them identify inaccurate broadband data for tribal lands, and share tribal questions and concerns with the appropriate FCC bureaus. However, FCC does not have a formal process for tribes (or other governmental entities) to provide input to ensure that the broadband data FCC collects through the 477 process, or the resulting maps that FCC creates to depict broadband on tribal lands, are accurate. Similarly, FCC does not use other methods to verify provider-submitted Form 477 data on tribal lands against other sources of information, such as on-site tests or data collected by other agencies. When discussing the lack of a formal process for tribal representatives or other governmental entities to provide feedback on the accuracy of the 477 broadband data, FCC officials noted that if consumers and local officials have information on individual locations that lack broadband service, such information does not indicate that the entire census block lacks broadband service. Additionally, FCC officials noted that providers attest to the accuracy of the data and that FCC staff validate the data by conducting internal checks to identify possible errors, such as unlikely changes in a providers’ coverage area, and may follow-up with a provider to discuss such changes. However, these checks do not include soliciting input from tribes. About half of the tribal stakeholders we spoke to raised concerns that FCC’s broadband deployment data rely solely on unverified information submitted by providers. Additionally, most tribal stakeholders we interviewed told us that consistent with the recommendations in the National Broadband Plan, FCC should work directly with tribes to obtain information from them to improve the accuracy of its broadband deployment data for tribal lands. These stakeholders identified several ways in which FCC could work with tribes on this issue, including: conducting on-site visits with tribal stakeholders to observe the extent to which broadband infrastructure and services are present; conducting outreach and technical assistance for tribal stakeholders to raise awareness and use of FCC’s broadband data; and providing opportunities for the tribes to collect their own data or submit feedback regarding the accuracy of FCC’s data. FCC’s National Broadband Plan notes the importance of supporting tribal efforts to build technical expertise with respect to broadband issues, and federal internal control standards state that federal agencies should obtain quality information from external entities. Officials we interviewed in FCC’s Office of Native Affairs and Policy told us that they provide some outreach and technical assistance to tribal officials at regional and national workshops, and FCC officials stated that they conducted specific outreach to tribal entities regarding the Mobility Fund Phase II challenge process, while, about half of the tribal representatives we spoke to stated that they were not aware of the Form 477 data or corresponding maps, or raised concerns about a lack of outreach from FCC to inform tribes about the data. Some tribal stakeholders stated that if FCC were to solicit tribal input as part of its verification of the broadband data and maps, technical training and assistance could help tribes use and provide feedback on the data, or improve the collection and submission of their own data. A few of the stakeholders we interviewed noted that tribes can face difficulties when they attempt to challenge FCC’s broadband availability data. For example, in 2013, prior to the auction that distributed Tribal Mobility Fund Phase 1 support, FCC allowed interested parties to challenge FCC’s preliminary determinations regarding which census blocks lacked 3G or better service and would be eligible for support in the auctions. However, all of the tribal entities that challenged the accuracy of FCC’s data were unsuccessful in increasing the number of eligible areas. According to FCC officials, the tribal entities did not provide sufficient or sufficiently verifiable information to support their challenges. A few tribal stakeholders provided varying reasons for this, one of which was the need for more technical expertise to help the tribe meet FCC’s requirements. Because FCC lacks a formal process to obtain tribal input on its broadband data, FCC is missing an important source of information regarding areas in which the data may overstate broadband service on tribal lands. Tribal stakeholders are able to provide a first-hand perspective on the extent to which service is available within their lands and the extent to which factors like affordability, service quality, and service denials affect residents’ ability to access broadband. FCC plans to award nearly $2 billion in support from the Connect America Fund to areas that it has identified as lacking broadband, including tribal lands. Any inaccuracies in its broadband data could affect FCC’s funding decisions and the ability of tribal lands to access broadband in the future. Additionally, in its 2017 report on tribal infrastructure, the National Congress of American Indians stressed the importance of including tribal governments in a leadership role with respect to collecting data on local infrastructure needs. Specifically, it stressed the need for the federal government to invest in tribal data systems and researchers to generate useful, locally specific data that can inform the development and implementation of infrastructure development projects and assess the effectiveness of those projects over time. By establishing a process to obtain input from tribal governments on the accuracy of provider- submitted broadband data that includes outreach and technical assistance, as recommended in the National Broadband Plan, FCC could help tribes develop and share locally specific information on broadband access, which would in turn improve the accuracy of FCC’s broadband data for tribal lands. The success of such an effort may rely on the tribes’ knowledge of, and technical ability to participate in, the process. When discussing the need to improve data regarding broadband on tribal lands, FCC’s 2010 National Broadband Plan recommended that FCC develop a process for tribes to receive information from providers about broadband services on tribal lands. In 2011, FCC required that Eligible Telecommunications Carriers (providers receiving Universal Service Funds from FCC) serving tribal lands meaningfully engage with tribes regarding communications services (including broadband). Specifically, the providers must file an annual report documenting that this engagement included a discussion of, among other things, a needs assessment and deployment planning for communications services, including broadband. FCC’s 2012 guidance on fulfilling the engagement obligations, which FCC officials confirmed is still in effect, noted that the stated goal of the engagement requirement was to benefit tribal government leaders, providers, and consumers by fostering a dialogue between tribal governments and providers that would lead to improved services on tribal lands. The guidance further noted that the tribal engagement process “cannot be viewed as simply another ‘check the box’ requirement by either party,” and states that a provider should “demonstrate repeated good faith efforts to meaningfully engage with the tribal government.” Finally, FCC noted in its 2012 guidance that the guidance would evolve over time based on the feedback of both tribal governments and broadband providers and that FCC would develop further guidance and best practices. This approach is consistent with federal internal control standards, which call for agencies to communicate with, and obtain quality information from, external parties. About half of the tribal stakeholders we interviewed raised concerns about difficulties accessing information from providers regarding broadband deployment on their tribe’s lands, a key part of the provider engagement process, according to FCC’s guidance. For example, a representative from one tribe stated that a provider declined his requests to meet more than once a year to discuss the provider’s deployment of broadband services on the tribe’s land. A representative from another tribal government stated that some providers are very focused and transparent about their broadband plans and work with the tribe, while other providers treat tribal engagement as a “box to check” and send the tribe broadband deployment information that is not useful because it is redacted. Similarly, some tribal stakeholders stated that providers heavily redacted deployment information (which providers may consider proprietary) or required the tribe sign non-disclosure agreements to access deployment data. According to one tribal stakeholder, these non-disclosure agreements could possibly require tribes to waive tribal sovereign immunity in order to view the data. Some of the industry stakeholders we interviewed stated that they attempt to engage with tribes but the level of responsiveness from tribes varies. For example, some stakeholders stated that they send letters and do not hear back from tribes. One stakeholder stated that they make repeated attempts to contact tribes when they do not hear back after their initial contact, while another stated that a provider meets regularly with some tribes. Although FCC stated in its 2012 guidance that it would update the tribal engagement guidance and develop best practices based on feedback from tribal governments and broadband providers, it has taken limited steps to obtain such feedback from providers and tribal governments to determine whether its guidance is enabling meaningful tribal engagement. Additionally, FCC has not updated the guidance or issued best practices. Thus, FCC has limited information regarding whether its tribal engagement requirement is fulfilling its intended purpose. FCC officials we interviewed said that the Office of Native Affairs and Policy (ONAP) provided information and, in some cases, held training sessions about the tribal engagement obligation during workshops with tribal representatives, and encouraged representatives to contact ONAP with any concerns. ONAP officials also noted that they handle complaints from tribes regarding a lack of provider engagement and reach out to providers to address tribal concerns. ONAP officials stated that they have had internal discussions about whether the guidance is clear or needs revision, but this has not gone beyond internal discussions. A few of the tribal stakeholders provided examples of the benefits of providers engaging with tribes to ensure tribal representatives have access to information regarding broadband availability on their lands. For example, one representative stated that this information could help the tribes plan deployments by focusing on areas that they know the provider does not plan to serve. Another representative stated that tribal engagement could help improve the accuracy of FCC’s broadband maps. By obtaining feedback from both tribal stakeholders and providers on the effectiveness of FCC’s tribal engagement guidance to determine whether changes are needed, FCC would be better positioned to ensure that tribal governments and providers are sharing information in a manner that will lead to improved services on tribal lands. FCC has collected data and developed maps and reports depicting broadband on tribal lands and has noted the lower levels of broadband access on tribal lands, in comparison to other areas. However, limitations in FCC’s existing process for collecting and reporting broadband data have led FCC to overstate broadband access on tribal lands. By taking steps to address these limitations and to collect data that more accurately and completely depict broadband access on tribal lands, FCC would have greater assurance that it is making progress on reducing the digital divide on tribal lands and targeting broadband funding to tribal lands most in need. Without taking these steps, FCC increases the risk that residents living on tribal lands will continue to lack broadband access. Compounding the limitations in FCC’s data collection process is FCC’s lack of a formal process to obtain tribal input on the accuracy of provider- submitted broadband data for tribal lands. By developing a process to solicit tribal input and ensuring that tribes know about the process and are equipped with the technical skills and abilities necessary to provide this information, FCC would be better able to ensure the accuracy of its broadband data for tribal lands. Moreover, FCC would be able to obtain firsthand, locally specific information on broadband access that could inform FCC’s policies and funding decisions and help FCC achieve its goal of increasing broadband access for all Americans, including those living on tribal lands. Finally, by obtaining feedback from providers and tribal stakeholders on the effectiveness of FCC’s tribal engagement guidance, FCC would be better positioned to assess whether its guidance is helping providers meet requirements and ultimately whether providers’ engagement is fulling its intended purpose of fostering a dialogue between tribal governments and providers that would lead to improved services on tribal lands. We are making the following three recommendations to the Chairman of the Federal Communications Commission. The Chairman of the Federal Communications Commission should develop and implement methods—such as a targeted data collection—for collecting and reporting accurate and complete data on broadband access specific to tribal lands. (Recommendation 1) The Chairman of the Federal Communications Commission should develop a formal process to obtain tribal input on the accuracy of provider-submitted broadband data that includes outreach and technical assistance to help tribes participate in the process. (Recommendation 2) The Chairman of the Federal Communications Commission should obtain feedback from tribal stakeholders and providers on the effectiveness of FCC’s 2012 statement to providers on how to fulfill their tribal engagement requirements to determine whether FCC needs to clarify the agency’s tribal engagement statement. (Recommendation 3) We provided a draft of this report to FCC for review and comment. In written comments provided by FCC (reproduced in appendix III), FCC agreed with our findings and recommendations. In its written comments, FCC described efforts, some of which are already under way, that it felt would address each recommendation and stated its intent to build upon those efforts. For example, FCC explained that it is exploring methods to collect more granular broadband deployment data and noted the need to balance the burden on Form 477 filers. FCC also noted that it is starting work to address a statutorily-required evaluation of broadband coverage on certain tribal lands. We agree that increasing the granularity of deployment data is helpful in addressing data accuracy issues, but we also note that it is important to collect data related to factors that affect broadband access on tribal lands. FCC also described informal efforts to collect tribal feedback on providers’ broadband data and stated it would explore options for a formal process to collect feedback. Regarding our recommendation related to providers’ engagement efforts, FCC outlined its existing methods by which tribal stakeholders can provide feedback on providers’ engagement efforts and agreed that seeking additional feedback from tribal stakeholders and providers would be desirable. We agree that improving feedback in these ways could help FCC determine whether it needs to clarify its tribal engagement statement. FCC also provided technical comments, which we incorporated as appropriate. We are sending copies of this report to the appropriate congressional committees, the Chairman of the Federal Communications Commission, and other interested parties.

This report discusses the extent to which: (1) the Federal Communications Commission’s (FCC) approach to collecting broadband availability data accurately captures the ability of Americans living on tribal lands to access broadband Internet services and (2) FCC obtains tribal input on the accuracy of provider-submitted broadband data for tribal lands. To address both objectives, we analyzed FCC’s December 2016 fixed and mobile broadband availability data—the most recent data at the time of our review—to identify the speeds, technologies, and availability providers reported for federally recognized tribal lands. Providers currently report this information to FCC by filing a “Form 477,” twice a year. We also used 2010 U.S. Census data to identify census blocks completely or partially on tribal lands. To assess the reliability of FCC’s data and 2010 U.S. Census data, we reviewed a previous GAO reliability assessment, and for FCC’s data we conducted electronic testing and analysis of the data, reviewed FCC guidance and documentation, and interviewed FCC officials. Based on the results of our analysis, we determined the data to be reliable for our purposes, which were: (1) to inform our selection of tribal governments and providers for interviews and visits, as described below, and (2) to develop maps depicting fixed and mobile broadband availability for the nine tribal lands we selected for visits, in order to obtain tribal representatives’ feedback on the data. Specifically, we mapped; fixed broadband data according to speed and technology, and mobile data for long-term evolution (LTE) services by provider for each tribal land. We used those maps during our visits to discuss the accuracy of the data with representatives for each tribal government or tribally owned provider. Though we analyzed all up and download speeds that providers reported in the Form 477, for the purposes of this report we defined “broadband” as fixed Internet service reaching at least 25 megabits per second (Mbps) download and 3 Mbps upload speeds, in accordance with FCC’s advanced telecommunications capability benchmark in its 2018 Broadband Deployment Report. We also report on the availability of mobile broadband, which, for the purposes of this report, does not have a speed threshold and refers to long-term evolution (LTE) services. To address both objectives and obtain tribal government representatives’ feedback on the accuracy of FCC’s broadband data for their lands, we interviewed representatives from 25 tribal governments or tribally owned providers, including visits to 9 tribal lands. We considered a range of factors when we selected tribal governments and tribally owned providers for interviews, including our analysis of Form 477 data, recommendations from tribal, industry, or government stakeholders regarding tribal and non- tribal representatives familiar with broadband data issues, and demographic and geographic characteristics, among others. For example, we considered demographic characteristics such as unemployment rate from the 2011– 2015 American Community Survey data, and geographic characteristics such as rurality from the United States Department of Agriculture (USDA) Rural-Urban Commuting Area Codes data. The tribes included in our review vary with respect to location, level of broadband availability according to FCC, land mass, and population size and density. The results of our interviews are not generalizable to all tribal governments or tribally owned broadband providers. In addition to tribal governments and tribally owned providers, we interviewed six tribal organizations and four stakeholders who work with tribes on broadband issues. For reporting purposes, we developed the following series of indefinite quantifiers to describe the tribal responses from the 35 entities representing tribal stakeholders we interviewed: 3 to 7 is defined as “a few;” 8 to 15 is described as “some;” 16 to 20 is described as “about half;” 21 to 27 is described as “most;” and 28 to 34 is described as “almost all.” A full list of the tribal stakeholders we interviewed can be found in appendix I. Further, to obtain industry perspectives, we reviewed public comments submitted by providers and industry associations in FCC’s ongoing 2017 Notice of Proposed Rulemaking on Modernizing the Form 477 Data Program. We also interviewed 10 non-tribally owned fixed and mobile broadband providers and three industry associations to understand providers’ views on the Form 477 and how providers interact with tribal governments. When selecting providers for interviews, we included providers that reported serving the lands of tribal governments we interviewed and selected providers that varied in the percentage of tribal lands they reported serving. The providers we interviewed represent large, nationwide carriers as well as small, local carriers, and offer broadband via a variety of technologies, including fiber optics, digital subscriber line (DSL), fixed wireless, and mobile LTE. The results of our interviews with providers are not generalizable to all broadband providers. In addition, to address both objectives, we interviewed representatives from other government entities, as well as private companies that collect and report broadband data. A full list of the industry stakeholders we interviewed can be found in appendix I. To identify the extent to which FCC’s approach to collecting broadband availability data reflects the ability of Americans living on tribal lands to actually access broadband Internet services, we reviewed documentation of the Form 477 process, including submission guidance, and FCC’s proposals and public comments in its 2017 Notice of Proposed Rulemaking on Modernizing the Form 477 Data Program and Mobility Fund Phase II proceedings. We also interviewed FCC officials, industry stakeholders, and tribally owned broadband providers to understand FCC’s current process for collecting broadband data. To understand the purpose of the Form 477 data collection process and FCC’s strategic goals, we reviewed relevant statutes, and FCC documents, including FCC’s Strategic Plan 2018––2022, the National Broadband Plan, and FCC’s broadband deployment and progress reports. Given the importance placed on broadband access in these documents, we interviewed tribal stakeholders, as described above and reviewed FCC documents to identify factors affecting the ability of Americans living on tribal lands to access broadband Internet services. We also reviewed previous GAO work that identified barriers to broadband access on tribal lands. We compared the Form 477 process to FCC’s strategic goals and to factors affecting broadband access to determine the extent to which the Form 477 was designed to collect information on those factors and to meet FCC’s goals. We further evaluated this information against the Government Performance and Results Act, as enhanced by the GPRA Modernization Act of 2010 and Standards for Internal Control in the Federal Government. We also reviewed documentation for other FCC data collection programs, including the Measuring Broadband America program and the Urban Rate Survey, to determine the extent to which FCC collected data on factors affecting broadband access outside of the Form 477 process. To determine the extent to which FCC obtains tribal input on the accuracy of provider-submitted broadband data for tribal lands, we interviewed FCC officials and analyzed FCC documents regarding the collection procedures for the Form 477 data and FCC’s policies for working with tribal governments, as well as Connect America Fund documents regarding requirements for providers to share information with tribal governments. We also reviewed documents on past FCC Universal Service Fund processes to challenge broadband data and identified prior instances in which tribal governments or tribally owned providers challenged FCC’s broadband data and the outcomes of those challenges. Additionally, we interviewed tribal stakeholders, as described above, to understand the extent to which: (1) FCC involves tribal governments and other stakeholders in the validation of Form 477 broadband data, (2) tribal governments can access broadband data from FCC or providers, and (3) FCC’s Form 477 data accurately reflected broadband access on their lands. For the nine tribal lands we visited, we asked tribal governments or tribally owned providers to identify where the data do or do not accurately reflect broadband access on maps of FCC’s data. Further, to identify how providers complied with FCC’s tribal engagement requirement and obtain their perspectives, we interviewed providers and industry associations. We compared FCC’s data validation procedures and tribal stakeholders’ feedback on the process to FCC’s policies for working with tribal governments, FCC recommendations from the National Broadband Plan and Standards for Internal Control in the Federal Government. We also interviewed and received written comments from officials from other federal agencies that have broadband programs, including USDA Rural Utilities Service, the National Telecommunications and Information Administration (NTIA), and others, in addition to a state agency and three private companies that collect and report broadband data to understand how other entities collect and validate broadband data. We conducted this performance audit from June 2017 to September 2018 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. Mark L. Goldstein, (202) 512-2834 or GoldsteinM@gao.gov.

Answer: Broadband furthers economic development, educational attainment, and public health and safety; however, residents of tribal lands have lower levels of broadband access relative to the U.S. population. Congress has prioritized identifying and targeting funds to unserved areas. FCC uses data from broadband providers to develop maps and reports depicting broadband availability in the United States, with specific information on tribal lands. GAO was asked to review FCC's efforts to collect broadband data for tribal lands. This report examines the extent to which: (1) FCC's approach to collecting broadband data accurately captures broadband access on tribal lands and (2) FCC obtains tribal input on the data. GAO interviewed stakeholders from 25 tribal governments or tribally owned providers, and visited nine tribal lands. The selected tribes varied geographically and in levels of broadband availability, among other characteristics. GAO also reviewed FCC's rulemakings on broadband data and interviewed other tribal stakeholders, FCC officials, and 13 non-tribal broadband providers selected to include a diversity of technologies. Provider and tribal interviews were based on non-generalizable samples. The Federal Communications Commission (FCC) collects data on broadband availability from providers, but these data do not accurately or completely capture broadband access on tribal lands. Specifically, FCC collects data on broadband availability; these data capture where providers may have broadband infrastructure. However, FCC considers broadband to be “available” for an entire census block if the provider could serve at least one location in the census block. This leads to overstatements of service for specific locations like tribal lands (see figure). FCC, tribal stakeholders, and providers have noted that this approach leads to overstatements of broadband availability. Because FCC uses these data to measure broadband access, it also overstates broadband access—the ability to obtain service—on tribal lands. Additionally, FCC does not collect information on several factors—such as affordability, quality, and denials of service—that FCC and tribal stakeholders stated can affect the extent to which Americans living on tribal lands can access broadband services. FCC provides broadband funding for unserved areas based on its broadband data. Overstatements of access limit FCC's and tribal stakeholders' abilities to target broadband funding to such areas. For example, some tribal officials stated that inaccurate data have affected their ability to plan their own broadband networks and obtain funding to address broadband gaps on their lands. By developing and implementing methods for collecting and reporting accurate and complete data on broadband access specific to tribal lands, FCC would be better able to target federal broadband funding to tribal areas that need it the most and to more accurately assess FCC's progress toward its goal of increasing all Americans' access to affordable broadband. FCC does not have a formal process to obtain tribal input on the accuracy of provider-submitted broadband data. In the National Broadband Plan , FCC highlighted the need for a targeted approach to improve broadband availability data for tribal lands. As outlined in the plan, such an approach would include working with tribes to ensure that information is accurate and useful. About half of the tribal stakeholders GAO interviewed raised concerns that FCC relies solely on data from providers, and most stated FCC should work with tribes to improve the accuracy of FCC's data. Establishing a formal process to obtain input from tribal governments on the accuracy of provider-submitted broadband data could help improve the accuracy of FCC's broadband data for tribal lands. GAO is making three recommendations to FCC, including that it collect and report data that accurately measure tribal broadband access as well as develop a process to obtain tribal input on the accuracy of the data. FCC agreed with the recommendations.
