Summary

Rex Mill Middle School is a public middle school located in Rex, Georgia, serving grades 6-8 with a total enrollment of 921 students. The school is part of the Clayton County School District, which is ranked 173 out of 206 districts in Georgia and has a 1-star rating from SchoolDigger. Despite some areas of strength, Rex Mill Middle School has consistently ranked in the bottom half of Georgia middle schools over the past several years.

One of the school's key strengths is its performance on certain subject-area exams. In 2024-2025, Rex Mill Middle School had 90.2% proficiency in Algebra I and 75% proficiency in Biology, significantly outperforming the Clayton County and Georgia averages. However, the school also has a very high percentage of students receiving free or reduced-price lunch, ranging from 88.06% to 90.55% over the past few years, indicating a high-poverty student population. Additionally, while Rex Mill Middle School outperforms the Clayton County averages in many subject areas, it still lags behind some of the higher-performing nearby schools, such as M.D. Roberts Middle School and Babb Middle School.

Despite the higher spending and free/reduced lunch rates, Rex Mill Middle School has consistently performed poorly, with a 1-star rating from SchoolDigger and a ranking in the bottom half of Georgia middle schools over the past several years. This suggests that factors beyond just funding and student demographics may be contributing to the school's underperformance, and the school may face significant challenges in terms of student support, resources, and addressing the needs of its high-poverty student population.
