Rex Mill Middle School, Rex GA - Test Scores & Data

Original Research by School Decision on Rex Mill Middle School

Rex Mill Middle School serves sixth through eighth grade in Rex, an unincorporated residential community about seventeen to twenty miles southeast of Atlanta. The school enrolls a student body that is predominantly Black, with a substantial Hispanic enrollment and a smaller share of other students. A very large share of students qualify for free or reduced-price lunch, reflecting the economic composition of the community.

The school's state test results show consistent proficiency challenges across subjects. In English language arts, proficiency rates hover around one quarter to slightly above, with modest variation by grade. Math proficiency is low in sixth and seventh grade, then rises noticeably by eighth grade, though still below half. The school administered science and social studies assessments in eighth grade only; proficiency in both ran around one quarter. Overall, the school's proficiency index places it in the top quartile among the five districts in Clayton County, meaning it performs better than most peers in the county comparison, though the county itself faces broad proficiency headwinds.

Rex sits in a car-dependent suburban-to-semi-rural setting of tree-shaded streets and midcentury ranch and split-level homes, with little commercial activity or employment within the community itself. The nearest full grocery shopping requires a drive to nearby Stockbridge. MARTA recently extended bus service into Clayton County, offering some public transit connection to surrounding areas. Rex Park provides recreational anchors with playgrounds, a community pool, athletic fields, and recreation programs. The historic Rex Mill, listed on the National Register of Historic Places, marks the area's cultural heritage.

Housing in the zip code area remains moderately affordable relative to state and national benchmarks, though prices have retreated slightly year over year. Rental housing dominates and is marketed primarily as older stock. The area shows modest population growth and some speculative development interest at the Henry County edge.

Clayton County Public Schools is in the midst of substantial capital restructuring. Voters approved a major education sales tax in 2023 to fund renovation or replacement of 36 aging schools, a multi-year reshaping that will directly affect which building families' children attend. The district is also opening a new convocation center and college and career academy hub in Morrow in 2025, expanding career pathway access for high schoolers. District-wide, the system has committed to Science-of-Reading-based literacy instruction, rolling out universal reading screeners and tutoring in all K-5 classrooms as part of a "CCPS...Where Literacy Lives" initiative aligned with Georgia's Early Literacy Act. These shifts signal the district's pivot toward evidence-based early intervention and career preparation, though a parent may want to look into the school's specific participation in these initiatives and the timing of any facility plans that could affect Rex Mill.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
