Summary:
Only one middle school serves zip code 28462 in Supply, North Carolina: Cedar Grove Middle, a grades 6–8 public school within Brunswick County Schools that enrolls 507 students. The school serves a virtually 100% economically disadvantaged population (99.41% free/reduced lunch) and contends with a chronic absenteeism rate of 34.7%, roughly ten points above the district (24.5%) and state (24.2%). Despite those obstacles, Cedar Grove earned two stars and improved from the 36th to the 44th percentile in state rankings between 2024-2025 and 2025-2026.
Because Cedar Grove is the only middle school within the zip code, there are no neighboring schools to compare it to; the most meaningful benchmarks are district and state averages. In 2025-2026, 6th grade math was a clear bright spot, with 65.1% proficiency versus 61.2% for the district and 59.2% for the state. However, 7th grade math dropped dramatically to just 38.0% (state average 56.2%), a trend not fully explained by district patterns. Conversely, the school posted striking year-over-year improvement in reading, with gains of +10.1, +10.9, and +9.3 points in grades 6, 7, and 8 respectively, and 8th grade science jumped +11.9 points to 67.5%, essentially at par with the state average of 68.6%.
The school sits in the 44th percentile among 778 North Carolina middle schools, trailing its district overall (Brunswick County Schools ranks in the 65th percentile of districts). Its student-teacher ratio of 15.2 to 1 and per-student spending of $11,326 (2018-2019) are reference data, but the operational picture is clear: Cedar Grove demonstrates resilience in 6th grade and meaningful literacy/science growth, yet 7th/8th grade math and chronic absenteeism are the two priority areas most likely to hold back future gains. For parents, Cedar Grove Middle's two-star rating masks a genuinely mixed profile: meaningful momentum in reading and science, competitive performance in 6th grade math, and tough structural headwinds in upper-grade mathematics and daily attendance.
