Summary:
Odyssey Charter School, the sole school in the State Specialty Schools I- Odyssey Charter School district, is a K-8 charter school in Newnan, GA, serving 359 students with a notably low 10.4:1 student-teacher ratio and per-student spending of $21,937.
This school presents a mixed performance profile. Its overall state ranking fell sharply from the 55th percentile in 2024-2025 to the 32nd percentile in 2025-2026, dropping its star rating from 3 to 2 stars. The most dramatic issue is in 5th grade, where math and science proficiency both sit at just 17.6%—roughly 26 points below state averages—representing a significant decline from the prior year. However, the school shows notable strengths in upper grades: 7th grade math proficiency (57.9%) exceeds the state by nearly 16 points, and 8th grade science (45.0%) and social studies (50.0%) both outperform state averages by double digits. The school also maintains a low chronic absenteeism rate of 10.7%, well below the state’s 17.7%.
Performance is highly cohort-dependent, with extreme year-over-year swings. The current 7th graders improved math proficiency by an extraordinary 31.8 points, while the 8th graders dropped by 15.9 points. Tracking the cohort that was in 4th grade in 2024-2025 (23.8% math) to 5th grade in 2025-2026 (17.6% math) reveals two consecutive years of significant underperformance, suggesting a persistent challenge for this specific group. While the school’s high spending and small class sizes have not consistently translated into top-tier results, its most recent ELA scores (2024-2025) were strong in 3rd, 6th, and 8th grades, all exceeding state averages by 12 or more points. Parents should weigh the school’s excellent attendance and upper-grade strengths against the concerning 5th grade performance and overall ranking decline.
