Cobb County Students Top State and National ACT Averages
Cobb County students in Georgia earned an average ACT composite of 23.0 for the class of 2026, above the Georgia average of 20.9 and the national average of 19.2, the district reported October 16.
Cobb County ACT scores for the class of 2026 once again topped state and national averages, the Cobb County School District reported on October 16. Students earned an average composite score of 23.0 out of a possible 36 points, above the Georgia average of 20.9 by 2.1 points and above the national average of 19.2 by 3.8 points. The district said five students in the graduating class earned a perfect score of 36, an exceptional result on a test that covers English, math, reading, and science. The results follow strong SAT results for the same class, and district leaders linked the scores to steady classroom work and support from teachers, students, and families.
The subject averages show broad strength rather than a single standout area. Cobb students averaged 22.4 in English, 22.6 in math, 24.0 in reading, and 24.0 in science, each above the Georgia and national averages. Wheeler High School led the district with an average composite of 28.0, followed by Walton at 26.3 and Lassiter at 25.5. Those school-level figures reflect different student populations and course patterns, so they should be read as a guide to local strengths, not as a simple ranking.
What Cobb County ACT scores show
Cobb County ACT scores matter because the ACT remains a familiar benchmark for college readiness, even as many colleges have changed their testing rules. A composite near 23 signals solid preparation in reading, math, and science reasoning, and it can help students qualify for scholarships and placement. Nationally, the average ACT composite for recent classes has been near 19, so a district average several points higher stands out. The gap also reflects the value of early preparation, consistent attendance, and access to advanced courses, all of which shape test performance over years rather than weeks.
For students still preparing, the Cobb results offer practical lessons. Regular practice with timed reading and math, careful review of mistakes, and steady work in core courses matter more than last-minute cramming. Students who retake the test often improve, and national data show that about a third of ACT takers test at least twice and raise their composite by an average of 1.1 points. Counselors advise students to check each college list before deciding whether to submit a score, since rules vary.
