High Schools in Cook County

Cook County, Georgia is home to a single public high school, Cook High School, which serves grades 9 through 12 and enrolls 895 students in the Adel area. This school has demonstrated a remarkable upward trajectory, jumping from a 3-star rating to a 4-star rating and climbing 85 positions in the state rankings to land at 100th out of 455 Georgia high schools (78th percentile) for the 2025–2026 school year.

Parents will be pleased to learn that Cook High School boasts an exceptional 98.5% graduation rate—more than 11 points above the state average—and a favorable 13.4:1 student-teacher ratio. The school's standout academic strength is Algebra I, where 71.9% of students scored proficient or above in 2025–2026, a stunning 30.3-point improvement from the prior year and nearly 24 points above the state average. However, performance is uneven across subjects: Biology proficiency (49.8%) sits just above the state average, while U.S. History proficiency (40.7%) declined by 7.4 points year-over-year, though it remains slightly above the state. The Cook County district metrics mirror the school's exactly, as it is the only high school in the district.

One area of concern is chronic absenteeism, which stands at 20.0%—higher than both the district (17.1%) and state (17.7%) rates. This is notable given the school's strong academic gains, suggesting that reducing absenteeism could unlock even greater improvements. With per-student spending of $12,269, the school achieves above-average outcomes efficiently. The dramatic one-year turnaround in Algebra I, combined with a top-100 ranking and near-perfect graduation rate, indicates a school on the rise. While Biology and U.S. History proficiency remain areas for growth, the school's overall trajectory is highly positive, making it a solid choice for families in the area.
