Summary:

ZIP code 62550 has two schools serving grades 2–12: Gregory Intermediate for grades 2–5 and Central A & M High School for grades 9–12, both in Central A & M CUD 21. The schools serve different age groups and have different current assessments, so their test results are not a like-for-like comparison. The clearest overall finding is that Gregory’s reported results are above state benchmarks across its tested subjects, while Central A & M’s results are mixed and its math scores are consistently below state levels.

Gregory Intermediate stands out relative to the state: its 2025–26 results were 63% in ELA versus 56% statewide, 47% in math versus 40%, and 66% in fifth-grade science versus 48%—gaps of 7, 7 and 18 percentage points. At Central A & M High School, all three grade-11 ACT results were below state levels, including math at 30% versus 40%. Math was also below the state on the grade-10 PreACT (27% versus 36%) and grade-9 PreACT (26% versus 42%). Its grade-10 science was slightly above the state, at 50% versus 48%, while grade-10 ELA was nearly even (+0.1 percentage point).

Recent results show improvement as well as setbacks. At Gregory, all-grades ELA rose 10 percentage points from 2024–25 to 2025–26, math rose 2 points, and fifth-grade science rose 20 points; each improved more than its state comparison. Central A & M’s grade-11 ACT math and science rose 16 and 8 points, and grade-10 PreACT math and science rose 13 and 6 points, but grade-9 PreACT ELA and math fell 18 and 11 points. SchoolDigger’s statewide percentile was steadier for Gregory—60th in 2025–26, near 60 in each of the three listed years—than for Central A & M, which was at the 42nd percentile after 53rd and 32nd. Enrollment was 200 at Gregory and 215 at Central A & M; in 2024–25, free/reduced lunch eligible students were 42% and 39%, respectively. Student-teacher ratios were 11 and 9.3. These figures provide context, not explanations for achievement differences.
