Law enforcement officers (LEOs)

within the federal government play

a key role in maintaining the safety 

and security of federal property, 

employees, and the general public.

In this report, we describe the 

number of LEOs that federal 

civilian law enforcement 

components employed as of 

June 30, 2006; the federal job series 

classifications the components 

used to employ LEOs; and the 

sources of their primary legal

authorities. 

To identify federal components 

that employ LEOs, we consulted, 

among other sources, the Federal 

Citizen Information Center’s 

Cabinet Agencies and Independent

Agencies and Commissions 

Directory; a list of organizations 

included in the Federal Law 

Enforcement Training Center 

(FLETC) 2004-2005 List of Agencies 

Trained at FLETC; and federal 

agencies listed in Federal Law 

Enforcement Officers, 2002, 

published by the Department of 

Justice’s Bureau of Justice 

Statistics (BJS). 

We identified 104 federal civilian 

law enforcement components and 

administered two Web-based 

ys to each—one y on the

primary authorities and the other 

y on the job series 

classifications.

 We defined an LEO 

as an individual authorized to 

perform any of four specific 

functions: (1) conduct criminal

investigations, (2) execute search

warrants, (3) make arrests, or 

(4) carry firearms. 

The 104 federal components we surveyed reported a total of 137,929 LEOs as 

of June 30, 2006, who were authorized to perform at least one of 4 specified 

law enforcement functions. These 104 components operate within 

14 departments and 28 nondepartmental entities. Seven of the 

104 components account for 93,263 (68 percent) of all LEOs (see fig. 1). 

Six of these 7 components are within the Department of Justice (DOJ) or 

Department of Homeland Security (DHS). DOJ and DHS accounted for 

108,324 (79 percent) of the total civilian LEOs—58,489 and 49,835 

respectively.

The components reported using 211 different job series classifications or 

titles for their LEOs. They also reported employing 121,821 LEOs under 

188 Office of Personnel Management (OPM) job series classifications and 

16,108 LEOs under 23 non-OPM job series or titles. The most widely used 

OPM job series is the 1811 criminal investigator series used by 71 different 

LEO components. The next three job series with the largest number of LEOs 

were the 1895 Customs and Border Protection officer series, the 0007

correctional officer series, and 1896 Border Patrol agent series. 

All of the components cited federal statutes as a primary source of their 

authorities to perform law enforcement functions. Additionally, 

40 components reported federal regulations, rules, or procedures as primary 

sources of authority. Other sources included memorandums of 

understanding, presidential directives, internal directives and orders, and 

delegation of authority from other federal agencies.

We provided a draft of this report to the 104 components included in the 

survey for comment. We received a number of technical comments, which 

we incorporated in the report where appropriate.

ongoing, and as agreed with your office, we plan to provide the training 

information in a separate report.

To determine which federal components had LEOs, we reviewed federal

law enforcement statistics and other federal law enforcement directories.

To collect the LEO information on these components, we then 

administered two Web-based surveys—one on the primary sources of 

authorities cited for the specified law enforcement functions and the other

on the job series classifications used for such LEOs. Copies of the two 

surveys can be viewed via the electronic supplement link provided in the 

first paragraph on page 1. The U.S. Office of Personnel Management 

(OPM) generally determines numeric classifications for LEOs by job series 

and titles. In some cases, according to OPM officials, non-OPM job 

classifications are used where OPM has delegated to individual 

components the ability to classify their own job titles. All job series 

information in this report reflects OPM’s series classification unless 

otherwise noted. This report contains self-reported information from each 

LEO component surveyed. While we did not independently verify the 

accuracy of the information provided to us, after receiving the completed 

surveys, we conducted quality control checks by analyzing the responses 

to identify inconsistencies and contacted survey respondents to reconcile 

any inconsistencies. We also returned copies of the survey responses as 

they appeared in our draft report to each agency for comment. Each law 

enforcement component was offered the opportunity to make any 

corrections to its original responses. A more detailed explanation of our 

scope and methodology is in appendix I.

Our work was conducted from January 2006 through November 2006 in 

accordance with generally accepted government auditing standards.

criminal investigations, execute search warrants, make arrests, or carry 

firearms. The 104 LEO components operate within 14 departments and 

28 nondepartmental entities. (App. II shows a breakdown of the 

104 components by department or nondepartmental entity). Seven of the 

104 civilian components account for 93,263 LEOs, or 68 percent of all 

LEOs, as shown in figure 1. Six of those 7 components are within either 

the Department of Justice (DOJ) or Department of Homeland Security 

(DHS), and the remaining component employs probation and pretrial 

services officers within the Administrative Office of the U.S. Courts 

(AOUSC). DOJ and DHS account for a total of 108,324 (79 percent) of the 

total civilian LEOs, 58,489 and 49,835 respectively.

211 Different Job Series 

Are Used for Employing 

LEOs 

The 104 civilian components we surveyed reported using 211 different job

series classifications for employing their LEOs: 188 OPM job series and 

23 non-OPM job series or titles. The components reported employing a 

total of 121,821 LEOs under the OPM job series and 16,108 LEOs under the 

non-OPM series, as of June 30, 2006. See appendix III for a list of the OPM 

job series and titles and appendix IV for a list of the non-OPM job series 

and titles by component. Figure 2 shows the four law enforcement job 

series with the largest number of federal LEOs, which, in total, account for 

63 percent (86,712) of all LEOs. (App. V lists the job series/titles and 

federal components with more than 1,000 LEOs.)

OPM assigns specific numerical codes to the various job series for the 

purposes of identification and human resources management. OPM job 

series are part of occupational groups or job families that include all 

classes or positions at the various skill levels in a particular kind of work. 

As indicated in figure 2, the OPM job series reflecting the most federal 

civilian LEOs was the 1811 criminal investigator series. In addition to the 

1811 job series, the next three job series with the largest number of LEOs 

were the 1895 Customs and Border Protection officer series, the 

0007 correctional officer series, and 1896 Border Patrol agent series.

investigators), were reported as being used across a number of different 

components. Other law enforcement job series were specific to particular

components, such as job series 1895 Customs and Border Protection 

officers within DHS and job series 0462 Forestry Technician within the 

Department of Interior. The 1811 criminal investigator series was the most 

commonly used series across the LEO components we surveyed—71 of 

the 104 components. Table 1 shows the 15 OPM-designated job series that 

were reported as used by more than one LEO component.

Components may use multiple job series for employing their LEOs.

According to OPM, the difference between the 1801 and 1802 job series classifications is that 

1802 positions have a support role (“perform or supervise inspectional or technical support work”) in 

assuring compliance with or enforcement of federal law, regulations, or other mandatory guidelines. 

Positions in the 1801 job series “administer, coordinate, supervise or perform inspection, 

investigative, analytical or advisory work.”

Among the four most widely-used OPM job series, the components 

reported that the law enforcement functions authorized to be performed 

by 1811 criminal investigators and 0083 police officers were generally 

consistent across those series. See appendix VI for the authorized law 

enforcement functions of the four most used OPM job series by 

component. For example, 62 of the 71 components using the 1811 job

series reported that their 1811 LEOs were authorized to perform all four 

functions—conduct criminal investigations, execute search warrants, 

make arrests, and carry firearms. Similarly, the LEOs in the 0083 job series 

for 11 of the 15 components using that series were reported as authorized 

to perform all four functions.

Components using the other two most widely used OPM law enforcement 

job series—the 1801 general inspection series and the 0080 security 

Page 6 GAO-07-121 Federal Law Enforcement
administrative series—reported that the law enforcement functions their 

components were authorized to perform varied widely. For example, for 

the 18 components using the 1801 job series, 5 components reported their 

LEOs were authorized to perform all 4 law enforcement functions. Law 

enforcement functions among the other 13 components varied. Similarly, 

among the 13 components using the 0080 job series, 7 reported that their 

LEOs were authorized to conduct criminal investigations and the other 

6 reported that they were not authorized to conduct criminal 

investigations.

Although law enforcement components responding to our survey reported 

using 188 different OPM job series, 153 of these job series designations 

were used exclusively by DOJ’s Federal Bureau of Prisons (BOP).

According to BOP’s survey responses, 16,216 of its total of 34,200 

employees are designated in the 0007 correctional officer job series. Law 

enforcement personnel in the 0007 job series are responsible for the 

correctional treatment, custody, and supervision of criminal offenders.

The remaining 17,984 employees are in other occupations, including job

titles such as sports specialist, chaplain, secretary, metal worker, 

electrician, plumber, pharmacist, language specialist, maintenance 

mechanic, cook, and gardener. According to BOP, these personnel also 

have primary responsibility for the supervision of inmates, have arrest and 

firearms authority, and receive annual training to reinforce the application 

of correctional techniques, as well as emergency procedures.

Components Cited a Wide 

Range of Authorities for 

Their Law Enforcement 

Functions 

The 104 federal components collectively cited a wide range of sources for 

their primary authorities to perform any of the four specified law 

enforcement functions. All of the components we surveyed included 

federal statutes (e.g., United States Code) as a source of their primary 

authorities. In addition, 40 components reported authorities derived from 

federal regulations (e.g., Code of Federal Regulations), rules, or 

procedures. As shown in table 2, components also cited, for example, 

memorandums of understanding and cooperative agreements with other 

federal, state and local agencies; presidential directives and executive

orders; internal directives and orders; and delegation of authority from 

other federal agencies, such as the General Services Administration. (See

app. VII for a list of components and their reported sources of primary 

authorities other than federal statutory sources.) A complete list of each 

component’s primary authorities, as reported by the components, can be

Appendix I: Scope and Methodology Appendix I: Scope and Methodology 

We administered two Web-based surveys to obtain information from 

federal civilian components with law enforcement officers (LEO). Copies 

of the two surveys can be viewed via the link in the first paragraph on page 

1 of this report. The first survey requested that each component state its 

law enforcement mission and list the primary authorities for their LEOs to 

perform any of the following four law enforcement functions: (1) conduct 

criminal investigations, (2) execute search warrants, (3) make arrests, or 

(4) carry firearms. The types of authorities sought through the survey were 

those based on statutory sources, (e.g., United States Code), regulatory 

sources, (e.g., Code of Federal Regulations), and other sources, such as 

executive orders, agency directives, or memorandums of understanding 

between agencies. This survey was administered between June 2006 and 

October 2006. We obtained a 100-percent response rate for the law 

enforcement authority survey.

The second survey requested that each component list the job series of the 

LEOs who were authorized to perform at least one of the four law 

enforcement functions mentioned above and the number of LEOs 

employed for each job series as of June 30, 2006. This survey was 

administered between August 2006 and October 2006. We obtained a 

100-percent response rate for the job series survey.

Since our surveys were not sample surveys, there are no sampling errors. 

However, the practical difficulties of conducting any survey may introduce 

errors, commonly referred to as nonsampling errors. For example, 

difficulties in how a particular question is interpreted by respondents, in 

the sources of information that are available to respondents, or in how we 

processed and analyzed the responses we received can influence the 

accuracy of the survey results. We took steps in the development of the 

surveys, the data collection, and the data analysis to minimize these 

potential nonsampling errors and help ensure the accuracy of the answers 

that were obtained. An independent analyst reviewed all of the computer 

programs used in the processing of the data.

To help identify which types of law enforcement functions would be used

to define an LEO for the purposes of our surveys, our analysis included 

consulting our previous work on federal law enforcement authorities and 

Page 9 GAO-07-121 Federal Law Enforcement
Appendix I: Scope and Methodology 

personnel,

1 reviewing law enforcement related documentation from the 

U.S. Office of Personnel Management,2 and interviewing officials with 

expertise in law enforcement functions of various civilian agencies 

employing LEOs.

To determine which federal components might employ LEOs performing 

any of the four functions listed above, we compiled an initial list based on 

the federal agencies: 

• listed in Federal Law Enforcement Officers, 2002, published by the 

Department of Justice’s Bureau of Justice Statistics (BJS);

• identified as partner organizations of the Department of Homeland 

Security Federal Law Enforcement Training Center (FLETC), where 

federal law enforcement agencies agreed to train their LEOs, and other 

agencies included in FLETC’s 2004-2005 List of Agencies Trained at 

FLETC; and 

• listed in the Federal Citizen Information Center’s Cabinet Agencies and 

Independent Agencies and Commissions Directory.

The term “federal law enforcement officer” can be defined in numerous 

ways depending on the information sought. To best meet the information 

needs of the requester and the time frame for reporting, it was necessary 

to limit our scope to law enforcement officers employed directly by the

federal government as well as exclude certain agencies or components. 

We refined the list of federal components to survey by submitting our 

initial list to the components’ parent departments and nondepartmental 

entities for corrections and additions. This compilation is not intended to 

reflect all personnel in the federal law enforcement community. We did

not include contract services, civilian law enforcement officers and 

investigators within the Department of Defense (DOD) or the DOD Offices

To identify the specific information to collect in our surveys, such as 

components’ law enforcement missions, the job series classifications they

use for employing their LEOs, and the types of law enforcement 

authorities, we conducted initial interviews with Department of Homeland 

Security’s and Department of Justice’s officials with law enforcement 

expertise. We developed and pretested both of our surveys with three 

components with diverse missions, and of varying sizes (e.g., National 

Park Service of the Department of Interior, Immigration and Customs 

Enforcement of the Department of Homeland Security, and the U.S. 

Government Accountability Office) to ensure the questions were clear and 

unambiguous. Upon completion of the pretest, we made necessary 

changes to the final surveys prior to nationwide implementation.

To help ensure sending the surveys to knowledgeable component officials 

(e.g., officials with legal or human resources knowledge), we requested 

the designated GAO liaisons of each component to identify these 

knowledgeable officials and provide their contact information. We also 

followed up with these officials to clarify survey responses, if necessary. 

All of the data in this report are what were reported by the 104 civilian 

LEO components through our Web-based surveys. Copies of the two 

surveys can be viewed via the link in the first paragraph on page 1. We did 

not independently verify the accuracy of the information provided to us.

We did, however, after receiving the completed surveys, examine the 

survey results and performed computer analyses to identify 

inconsistencies and other possible indications of error (e.g., inconsistent 

listing of law enforcement job series between the authority survey and the 

job series survey). Also, we conducted quality control checks via 

telephone and e-mail with the survey respondents to follow up on possible 

internal data inconsistencies or other issues needing clarification, such as 

unanswered questions or data entry errors. Where possible, we compared 

the law enforcement job series and number of LEOs in the job series 

survey with information available from the Bureau of Justice Statistics, the 

September 2005 Central Personnel Data File of the Office of Personnel 

 3

According to a DOJ official, many DOJ attorneys are authorized to conduct criminal 

investigations and routinely manage such investigations as Assistant United States 

Attorneys, Legal Division Trial Attorneys, or in related positions.

Management, and documents collected from 27 of the components in our 

prior work. 

We also returned copies of the survey responses as they appeared in our 

draft report to each agency for comment. Each law enforcement 

component was offered the opportunity to make any corrections to its 

original responses. A number of the law enforcement components 

provided technical corrections, additions, and or deletions to its original 

responses. These technical comments were incorporated in the report 

where appropriate.
