The Georgia Department of Education released 2018 CCRPI scores today. The CCRPI is a formula of mostly test scores and test score growth that rates schools on a 0-100 scale.

This year’s scores are not directly comparable to the previous year’s scores because the formula has changed. So, to better understand school CCRPI performance over time, the visual below shows each the state percentile rank of each school’s CCRPI score.

The results are sorted by the percentile rank of the three year average. CCRPI tends to fluctuate from year to year, so the three year average is more predictive of future performance. Note that the percentile rank of the three year average is not the same as the three year average of the percentile rank. In other words, averaging columns 2016-2018 will not produce the last column¹.

The percentile view is helpful for comparing across years and to the state, but it can exagerate differences for schools in the middle of the distribution. Use the “Choose Metric” filter to switch to CCRPI points or to the state percentile rank of progress points.

This year’s CCRPI is composed of the following categories:

• Content Mastery is worth 30% of CCRPI and is determined by student achievement on standardized tests (Georgia Milestones).
• Progress is worth 35% of CCRPI for elementary and middle and 30% for high. This metric measures student growth on standardized tests relative to the previous year.
• Closing Gaps is worth 15% of CCRPI for elementary and middle and 10% for high. Closing gaps is calculated based on test score improvement targets for student subgroups including economically disadvantaged, English Learners, students with disabilities and race/ethnicity groups.
• Readiness is worth 20% of CCRPI for elementary and middle and 15% for high. Readiness measures literacy, student attendance, and enrollment in certain non-core classes such as world language in elementary school or advanced placement in high school.
• Graduation is worth 15% of CCRPI for high school and is based on the cohort graduation rate.

See the resources here for more detail about the CCRPI categories.

The next visual shows 2018 CCRPI results by category. Each category score is converted to a state percentile rank to better demonstrate relative strengths and weaknesses.
