The equity details page shows three different measures of equity: achievement, growth and gaps. The achievement and growth measures are used to create the overall equity score.

Achievement:

Achievement uses the percentage of students who are proficient and above for five different subgroups: Black, Hispanic, English learners, Students with Disability, and low-income. Results with at least ten tested students are included. The subgroup achievement data used for this metric is from GOSA.

Growth:

Growth is a measure of how much growth are students demonstrating relative to academically similar students. This measure uses a weighted summary of subgroup growth scores, released in CCRPI data files. The growth scores come from GADOE’s Student Growth Model. SGPs of 1‐29 earn 0 points, 30-40 earn 0.5 points, 41-65 earn 1 point, and 66-99 earn 1.5 points. Growth data is reported if at least 15 students in a subgroup have growth scores.

The weighting of the equity growth scores differs from the simpler summary used in our overall growth ratings. This is because GADOE does not release subgroup growth using the simpler formula.

Gaps use the difference in the percentage of students who are proficient and above for five different types of gaps: Black-White, Hispanic-White, English Learner-non-English Learners, Students with Disabilities-students without disabilities, and low-income students- non-low-income students. A gap category is included if there are at least ten tested students in both groups. The subgroup achievement data used for this metric is from GOSA.

To calculate the overall equity score, the five subgroup scores are combined using a weighted average by the number of students to create scores for achievement and growth. Then, the score for both gap types is converted to a state percentile rank and the lowest of the two percentile ranks is selected. The resulting rank is a school’s equity score.

The gaps measure is not used for the overall equity score because this can penalize schools for having subgroups of high-performing students. Instead, the equity score is based on the performance of different groups within a school relative to the entire state.
