Sheet: Data Notes

Notes:
This file includes the 2013 gifted rankings as of Aug. 26, 2013.
This file was created in response to language in Ohio Revised Code (ORC 3302.21) that requires the Ohio Department of Education to rank traditional school districts, community schools and STEM schools based on the opportunities for, and performance of, students identified as gifted.
The full text associated with this section of law is available here:
ORC 3302.21
This file does not include rankings based on any other district- or school-level measures.
What organizations are included in this file?
Only districts and community schools reporting at least one student identified as gifted are included in this report. To be ranked, a district or community school needed to have more than 10 students identified as gifted, and sufficient numbers of students identified in tested grade levels and subject areas for both Performance Index and Value-Added index scores to be calculated. Community schools are not required to identify or serve gifted students.  As a result, very few reported sufficient numbers of gifted students to be included.
It should be noted that all organizations containing data were included when calculating each of the component ranks. Thus, although the report displays ranks for 548 districts, the Opportunity rank was based on the 628 districts reporting 10 or more students identified as gifted; the Performance Index rank was based on the 598 districts with a Performance Index calculated for the gifted subgroup, and the Value-Added ranking is based on the Value-Added subgroup data from 557 districts.
Schools that were closed in the Ohio Educational Directory System (OEDS) as of Aug. 26, 2013, are not included in this ranking file.
What is the Gifted Opportunity Rank?
The Gifted Opportunity rank uses a score based on the percent of all district students identified as gifted:  the percent of students identified as gifted who receive gifted services; and the percent of all district students who receive gifted services. The score takes into consideration the relative size of each of the components at the district level. The formula for the score is (the number of students identified + the number of students served +the number of students identifeid)/(the total enrollment +the number of students identified + the total enrollment).
Using this approach avoids a high Opportunity rank resulting from a district identifying a very few students, yet serving all of them. At the same time, it avoids a high Opportunity rank resulting from a district identifying many students as gifted, but providing few services.
What is the Performance Index?
The Performance Index is a calculation that measures student performance on the Ohio Achievement Assessments/Ohio Graduation Tests in grades 3, 4, 5, 6, 7, 8 and 10 (OGT).
You can learn more about the role of the Performance Index in Ohio's current accountability system by visiting the Ohio Department of Education's website using the following link:

What is Value-Added?
Value-Added is a growth measurement that assesses a district’s impact on student progress from year to year.
In 2013, Ohio produced Value-Added growth analyses for reading and math, in grades 4-8.

What do the data in each column mean?
Below is a description of the contents of each column.
Column | Description
Gifted ranking | Districts are ranked on the average of three separate components. This average is displayed in the column titled "Average of Gifted Component Ranks."
District name | District name.
County | District's Ohio Department of Education designated county, assigned based on the district's primary mailing address in the Ohio Educational Directory System (OEDS).
DIRN | Six-digit unique district identifier.
Status as of Aug. 24, 2013 | District organizational status, as listed in the Ohio Educational Directory System (OEDS) as of Aug. 24, 2013.
District type | Indicates whether the data represents a public district or a community school. For community schools, indicates whether school is a start-up or conversion school.
Total identified as gifted 2013 | Year-end Average Daily Membership (ADM) for district during 2012-2013 school year for students reported in any of the gifted categories: superior cognitive ability; specific academic ability; creative thinking ability; and visual or performing arts ability. There are four fields included in specific academic ability: mathematics; science; social studies; and reading or writing, or a combination of these two skills.
Total students receiving gifted services | Year-end Average Daily Membership (ADM) for a district during the 2012-2013 school year for students reported as having received gifted services.
Total enrollment 2013 | The sum of year-end Average Daily Membership (ADM) of students identified as gifted and those identified as not gifted for a district during 2012-2013 school year.
Average of gifted component ranks 2013 | This is the average of Gifted Opportunity rank, the gifted Performance Index rank, and the gifted Value-Added gain index rank.
Gifted Opportunity rank 2013 | The Gifted Opportunity rank uses a score based on the percent of all district students identified as gifted: the percent of students identified as gifted who receive gifted services; and the percent of all district students who receive gifted services. The rank shows the relationship among identification rates, gifted services and the total number of students enrolled in the district.
Gifted Performance Index 2013 | Based on results from all tested subjects, grades 3-8 and 10. Performance Index scores are only calculated in cases where there are at least 10 students contributing test data to a Performance Index score. The gifted Performance Index used for  ranking  is based on results of reading tests for students identified as gifted in reading or having superior cognitive abilities, results of math tests for students identified as gifted in math or having superior cognitive abilities, results of science tests for students identified as gifted in science or having superior cognitive abilities, and results of social studies tests for students identified as gifted in social studies or having superior cognitive abilities.
Performance Index rank 2013 | Rank of gifted [NAME].
Value-Added gifted gain index 2013 | The Value-Added gain index is a standardized measure of a district's Value-Added gain score and is calculated by dividing the district's Value-Added gain score by the district's Value-Added standard error.  Beginning in 2013, Ohio uses an up-to-3-year-average composite gain index for use in assigning [NAME] letter grades. The Value-Added gifted gain index rank  used the Value-Added index for  the subgroup of students identified as gifted.  The Value-Added calculations for the gifted subgroup are based on math and reading test results for students identified as gifted in reading, math, or superior cognitive abilities.
Value-Added gain index Rank 2013 | Rank of Value-Added gifted gain index 2013.
Value-Added gifted classification 2013 | Letter grade assigned to district's 2013 Value-Added gifted subgroup in Ohio's 2013 Accountability system.
