Milestones State Percentile Ranks, 2022

The view below converts average test scores for each school into a state percentile rank. This view is helpful for comparing 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, Burgess-Peterson’s 2022 average 3rd grade English score is in the 92nd percentile. This means their average scale score is as high as or higher than 92% of schools in Georgia. This is an increase from 85 in 2019.

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 was not administered in spring 2020, and although the Milestones were administered in 2021, APS take-rates were low and not representative.

  1. For example, 2022 state proficiency levels for range from 44% for fourth grade math to 31% 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.
