The state report cards are out, and the Cobb County School District once again returned high marks, outscoring peers across the state. The Georgia Department of Education uses the College and Career Ready Performance Index (CCRPI) to grade schools and school districts, and Cobb’s report card upheld the District’s reputation for excellence. Cobb exceeded Georgia’s scores in 12 of the 13 measurements while matching Georgia’s score in the 13th. 

“Across every subject and grade level, Cobb students are achieving remarkable gains because our teachers can focus on what truly matters—teaching,” said Board member David Chastain. “The success happening daily in Cobb classrooms is a direct result of our community’s investment and will continue to pay off for years to come.” 

Content Mastery: A Benchmark of Excellence

Cobb County excelled in Content Mastery at every school level, surpassing state averages by double digits for middle and high schools. Content Mastery measures the proficiency of all students on the Georgia Milestones, notably: 

• Elementary Schools: +9.2 points over the state average. 
• Middle Schools: +11.9 points over the state average. 
• High Schools: +15.1 points over the state average.

Moreover, year-over-year improvement in Content Mastery was impressive, with elementary and middle schools each gaining +3.8 points and high schools improving by +4.0 points. Cobb high school students also topped their Atlanta metro peers by as much as 29 percentage points.

Progress Across All Levels 

The Progress component also demonstrated strong gains across the district. Progress measures the growth demonstrated by all students from year to year on the Georgia Milestone, and a portion measures the year-to-year growth in English proficiency demonstrated by English learners on the Access test. 

• Elementary Schools: +3.9 points above the state average. 
• Middle Schools: +3.1 points above the state average. 
• High Schools: +8.7 points above the state average.

Year-over-year Progress improvements further highlighted Cobb’s focus on student growth, with gains of +4.0 points in elementary schools, +1.1 points in middle schools, and +1.6 points in high schools. 

Beyond the Core: Near-Perfect Scores 

Cobb students excelled in Beyond the Core indicators, which evaluate performance in fine arts, world language, CTAE, and PE for middle schools. Elementary schools scored 99.7, while middle schools achieved 99.5, demonstrating nearly flawless outcomes. 

High School Success: Graduation Rates

on the Rise Cobb high schools showed significant strides in graduation rates. The four-year graduation rate increased by +0.4 points, while the five-year cohort graduation rate climbed to 90.5%, marking a +2.8-point improvement over the previous year. 

The five-year rate is calculated using the same method as the four-year rate, except students are allowed one more year to graduate. Eleven of Cobb’s seventeen high schools recorded five-year graduation rates above 90%, and eight of those were 95% and above. Lassiter High School was within one percentage point of a perfect graduation rate. 

A Comprehensive Increase in Readiness 

Readiness scores also rose across the board in 2024, reflecting the Georgia Milestones Literacy metric; student attendance; and course completion, pathways, and tests that indicate students are ready for the next level of school or career. 

• Elementary Schools: +0.9 points. 
• Middle Schools: +0.8 points. 
• High Schools: +1.6 points.

These gains further underscore the district's commitment to preparing students for success in college, careers, and life. This is even more evident when the high school scores show that more Cobb students are ready for the next level than their Atlanta metro peers. 

Math and Literacy Leaders

Cobb’s success on the state report card is no surprise after the Georgia Department of Education recognized 69 Cobb schools as state leaders in math, literacy, or both in 2024.
