Summary:
ZIP code 88230 contains just one middle school: Dexter Middle, a grades 6–8 school in Dexter, New Mexico with 178 students, part of Dexter Consolidated Schools. Because it is the only middle school in the area, there are no local peers to compare it against — the useful benchmarks are the district, the state, and the school's own past years. Context matters here: 100% of students qualified for free or reduced lunch in 2024–2025, and the student-teacher ratio was 12.9.
Dexter Middle's results are mixed. Its brightest spot is 7th-grade English Language Arts, where 53.06% of students scored proficient — about 6 points above the state in both the NM Combined and NM-MSSA frameworks, and the highest grade-level figure the school reports. Overall ELA is close to state levels (42.28% versus 43.34% on NM Combined), though 6th-grade ELA runs about 6 points below state and 8th-grade ELA about 3–5 points below. Eighth-grade science improved notably, rising from 13.56% to 21.43% on NM-ASR, a gain of roughly 7.9 points, but it still trails the state by about 12–13 points. Math is the clear weakness: all-grades proficiency is 12.75% on NM Combined and 12.84% on NM-MSSA, below the district and less than half the state rate. Eighth-grade math sits around 16%, while 6th- and 7th-grade math are reported as under 20% — those figures are bounds, not exact values.
School rankings tell a story of rebound rather than full recovery. Dexter Middle ranked 83rd of 165 middle schools (50th percentile, 3 stars) in 2023–2024, fell to 143rd of 192 (26th percentile, 1 star) in 2024–2025, then climbed to 112th of 191 (41st percentile, 2 stars) in 2025–2026. Notably, the school's 41st percentile standing is stronger than its district's 14th percentile, 1-star rating. Parents should read these results as directional: with one school and some suppressed math scores, exact gaps can't be calculated, but math support stands out as the most important area to watch.
