Seven East Cobb schools surpassed the maximum scores in the latest CCRPI test results released Thursday by the Cobb County School District.
The CCRPI—which stands for College and Career Ready Performance Index—is a state accountability measure that gauges overall achievement results and how schools are preparing students for the next level of education.
The CCRPI is formulated on a 100-point scale as follows:
- Overall achievement comprising 50 percent (based on Georgia Milestones Assessment System);
- Student progress totaling 40 percent (Milestones results from year to year);
- The remaining 10 percent related to closing the achievement gap (between the 25 percent lowest-performing students in a school or district compared to all Georgia students).
Students at all three K-12 levels are tested, and the full state CCRPI results are available at the Georgia Department of Education website.
At the elementary school level, Timber Ridge (100.5), Murdock and Sope Creek (100.3 each) led all of Cobb, earning what’s referred to as “challenge” points in such categories as improved results among subgroups of students and innovative measures at a school, the so-called Exceeding the Bar (ETB) score.
Three Cobb middle schools, all in East Cobb, also exceeded the 100 mark: Dickerson (103), Dodgen (101) and Hightower Trail (101.5).
At the high school level, Walton’s score of 101.1 led the county as well. The high school achievement score includes graduation rates.
Cobb’s overall CCRPI score of 82.9 was higher than the statewide average of 75. For the high-scoring schools in East Cobb, those results were among the best in Georgia.
Timber Ridge’s score of 100.5 not only was a gain of 5.8 percent from 2016, but it’s one of the highest in the state (Lake Windward, in north Fulton County, topped out at 104.5). Timber Ridge scored 47.1 on achievement, a perfect 40 in progress, and earned 3.4 challenge points.
In a statement, Jeffrey Castle, the Timber Ridge principal, attributed his school’s results to “a supportive parent community, engaged students and motivated, highly-capable teachers who have the education of the whole child as their main priority.
“Our focus last year was on progress, with implementation of computer-based reading intervention programs, and on intentional delivery of rigorous instruction and congruency among curriculum, assessments and instruction.”
All but two of the 21 East Cobb elementary schools had higher scores than 2016, but the drops by Kincaid and Sedalia Park were slight.
The biggest jump was at Powers Ferry, with a score of 72.3 representing a 14.5 percent increase from a year ago, the fourth largest boost among Cobb elementary schools.
Although the achievement score at Powers Ferry was 26 and its progress was at 37, the school reported a score of 8.3 (out of 10) in closing the achievement gap.
In a release, Cobb schools said that measuring year-to-year progress in 2017 is not exact because of some minor changes to how the CCRPI is formulated. At all levels, science and social studies were removed as indicators in the progress and achievement gap categories.
