Best Middle Schools in Rex, GA

Rex, Georgia is served by two middle schools—Rex Mill Middle School and Adamson Middle School—both part of the Clayton County School District and both serving grades 6-8 in a high-poverty area where 100% of students qualify for free or reduced lunch.

Rex Mill is the larger school with 904 students and currently ranks 392nd in the state (32nd percentile), while Adamson has 509 students and ranks 403rd (30th percentile). Rex Mill stands out for its exceptional advanced coursework results: 100% of its 8th graders taking Algebra I scored proficient, more than double the state average, and 78.6% scored proficient in High School Physical Science. Adamson, despite lower math scores overall, actually outperforms Rex Mill in 8th-grade science (26.9% vs. 21.3%) and social studies (26.9% vs. 23.2%). Both schools show encouraging year-over-year gains in 6th and 7th-grade math—Rex Mill improved by 8.5 and 11 percentage points respectively, while Adamson gained 10.5 points in 6th grade—though both saw 8th-grade math decline. In the most recent ELA data (2024-2025), Rex Mill's 6th-grade proficiency was more than double Adamson's (24.9% vs. 11.8%), but the gap nearly disappears by 8th grade (27.4% vs. 25.7%).

Chronic absenteeism is a significant challenge at both schools, with rates near 24-25% compared to the state average of 17.7%, though both beat the district average of 28%. Interestingly, Adamson spends more per student ($17,670 vs. $15,893) and has a lower student-teacher ratio (12.4:1 vs. 13.9:1), yet Rex Mill achieves higher overall rankings—suggesting programmatic factors like advanced coursework matter more than spending alone. Both schools outperform their district's overall standing (19th percentile), making them relative bright spots in Clayton County. Note that ELA scores for the current year are not yet available; those results arrive in December.
