According to the National Assessment of Educational Progress (NAEP) 2024 reading report for Georgia 4th graders, the racial and ethnic composition of public school students was approximately 38% Black, 36% white, 17% Hispanic, 4% Asian, and 5% identifying as multiracial.

Chronic absenteeism remains a major issue in Georgia schools post-pandemic, with 20.7% of students missing 10% or more of school days in 2024, according to the Georgia Department of Education. In response, GaDOE launched a statewide initiative including a real-time attendance dashboard, a public awareness campaign, and targeted support for high-need districts to boost daily attendance.

In 2025, Georgia lawmakers passed a bill updating school attendance laws to ban expulsion solely for absenteeism. The law also adds new reporting requirements and aligns with programs that help students earn diplomas through alternative paths.

As of 2025, Georgia has an average student-to-teacher ratio of approximately 14:1, which is better than the national average of 15:1. The state’s best ratios are found in preschool, with an average of 13:1, and in elementary and middle school grades, both at 14:1, while high schools have a higher average ratio of 16:1.
