Summary:
Zip code 25404 in Martinsburg, WV is served by two public middle schools—Spring Mills Middle School and Martinsburg North Middle School—which together educate about 1,550 students in grades 6-8 within the Berkeley County Schools district.
Spring Mills is the stronger performer of the two, ranking 103rd out of 161 schools statewide (36th percentile) with a 2-star rating, while Martinsburg North ranks 140th (13th percentile) with a 1-star rating. The achievement gap between them is consistent across all subjects and grade levels—roughly 9-10 percentage points in both math and English Language Arts. For example, Spring Mills posts 28.5% math proficiency and 42.1% ELA proficiency, compared to Martinsburg North's 19.4% and 31.9%, respectively. Notably, Spring Mills excels in 7th grade math (35.3% proficiency, above the district average) and 8th grade science (30%, above both district and state averages). Martinsburg North, despite its low overall ranking, is only slightly below the state average in 8th grade science (27.1% vs. 29.3%).
Perhaps the most surprising finding is that Martinsburg North actually spends more per student ($11,947 vs. $10,844) and has a much lower student-teacher ratio (11.3:1 vs. 15.3:1) than Spring Mills, yet produces weaker results—suggesting that resources alone don't drive outcomes. Both schools struggle more with math than ELA, and both fall below district averages in most subjects. On a positive note, Martinsburg North has been slowly improving its state percentile over the past three years (from 4th to 13th percentile), while Spring Mills remains in the top half of the state. For parents, Spring Mills offers the stronger academic foundation, particularly in 7th grade math and science, while Martinsburg North may benefit from targeted math interventions despite its smaller class sizes.
