Summary:
Zip code 31620, serving the Adel, Georgia area, is home to just one high school, Cook High School, which serves grades 9 through 12 as part of the Cook County School District.
Cook High School is the only high school in this area, and it stands out for its exceptional graduation rate of 98.5%, which is more than 11 points above the state average of 87.2%. The school has also shown a dramatic improvement in its state ranking, jumping from 185th to 100th place in a single year, earning a 4-star rating. This upward trend is most visible in Algebra I, where proficiency soared from 41.6% to 71.9%—now nearly 24 points above the state average. However, performance is mixed across other subjects: Biology proficiency (49.8%) is slightly above the state average, while U.S. History (40.7%) is just above it, and American Literature (32.9% from the prior year) was the weakest area, falling well below the state average of 40.4%. With 895 students and a favorable 13.4:1 student-teacher ratio, the school spends $12,269 per student.
One notable concern is chronic absenteeism, which sits at 20.0%—higher than both the district (17.1%) and state (17.7%) averages. Despite this, the school maintains its high graduation rate, suggesting strong support for keeping students on track. Since Cook High School is the only high school in the district, its scores directly mirror district figures in most subjects. The school’s ranking has been volatile (139th to 185th to 100th), but its graduation success has remained consistently excellent. For parents, this is a school with clear strengths in graduation and math, but one that could benefit from addressing attendance and literacy gaps to sustain its recent gains.
