Best Public Schools in Zip Code 88230

Zip code 88230 covers Dexter, New Mexico, where three public schools — Dexter Elementary (PK–5), Dexter Middle (6–8) and Dexter High (9–12) — together enroll about 772 students as part of Dexter Consolidated Schools, a district ranked 75th of 87 in New Mexico (14th percentile, 1 star). All three schools report 100% free/reduced lunch, so this is a high-need system, and achievement results should be read with that context in mind.

Current ratings differ by building. Dexter Middle has the best school-level standing at 112th of 191 schools (41st percentile, 2 stars), followed by Dexter Elementary at the 34th percentile (2 stars) and Dexter High at the 20th percentile (1 star). Dexter High is the clearest concern, sliding from the 63rd percentile with 3 stars in 2023–2024 to the 20th percentile with 1 star in 2025–2026. Its bright spot is an 89.4% graduation rate, above the state's 80.6%. Dexter Middle also has the smallest classes, with a 12.9 student-teacher ratio versus 15.2 at the elementary and 15.5 at the high school.

Test scores show grade-level bright spots alongside a system-wide math weakness. Dexter Elementary's 3rd-grade ELA (53.49% on NM Combined) and 5th-grade math (42.55%) beat state rates, and Dexter Middle's 7th-grade ELA (53.06%) does too. But all-grade math is around 12.8% at the middle school versus 27.85% statewide, and 11th-grade math at the high school is under 10% on NM Combined, with 11th-grade science at 17.74% against the state's 34.02%.
