Summary:
Zip code 28025 in Concord, North Carolina, is served by two public middle schools—C C Griffin Middle and Concord Middle—both covering grades 6–8 and both belong to the same district, Cabarrus County Schools, yet the two schools present very different academic and socioeconomic profiles.
C C Griffin Middle is the stronger-performing school, ranking around the middle of North Carolina (48th percentile for 2025–26). It has a moderate free/reduced lunch rate of 54.8% and a chronic absenteeism rate of 17.3%, below the state average. On 2025–26 EOG tests, C C Griffin averages roughly 53% proficient in math and 55% in reading across grades 6–8, with several subjects right at or slightly above state averages. In contrast, Concord Middle ranks near the bottom of the state (16th percentile for 2025–26) and serves an intensely high-poverty population: 99.49% of students are eligible for free/reduced lunch, and 33.2% are chronically absent—nearly double the rate at C C Griffin. Concord’s math and reading proficiency averages are about 37%, leaving large gaps versus its local counterpart. The widest achievement gap is in 7th-grade math (54.3% vs. 31.3%, a 23-point difference), while the smallest gap is in 8th-grade science, where Concord performs relatively stronger.
There are encouraging signs despite the disparities. Concord Middle showed notable one-year improvement from 2024–25 to 2025–26, including a dramatic +24.9-point jump in 6th-grade math and +20-point gains in several other subjects. Concord also receives more funding ($9,893 per student vs. $8,618 at C C Griffin) and has a lower student-to-teacher ratio (16.2 vs. 18.5), likely reflecting its greater student needs. However, even the higher-achieving C C Griffin lags its district average in every subject—for example, 6th-grade math is 50.8% at C C Griffin versus 68.0% districtwide. For families, this means the zip code contains two very different school experiences; school-by-school data matters far more than geographic proximity.
