Milestones State Percentile Ranks, 2023

The view below converts average test scores for each school into a state percentile rank. This view helps compare performance over time across grades and subjects1 and to the rest of the state.

The percentiles show a school’s relative position among all Georgia schools. For example, Beecher Hill’s 2023 average 3rd-grade English score is in the 75th percentile. This means their average scale score is as high as or higher than 75% of schools in Georgia. This is an increase from 32 in 2022.

Use the filters to change to a different district or school or switch to a more traditional measure like percent proficient. Mouse-over a point to see its value or use the filter in the lower right to label all points.

Notice that the x-axis does not include 2020 or 2021. The Milestones were not administered in spring 2020, and although the Milestones were administered in 2021, APS take rates were low and not representative.

  1. For example, 2023 state proficiency levels range from 46% for fourth grade math to 33% for sixth grade math. A school or cluster that finds a 13-point gap in their own performance across grades might think they’ve found a large gap in instructional quality, when the gap might just be an artifact of varying exam difficulty. Using state percentile ranks helps difference out variation in exam difficulty.
