Summary:
ZIP code 67037 has two middle schools, Derby Middle School and Derby North Middle School; both serve grades 6–8, so families can compare them across the same grades. In 2025–26, their average proficiency was 38% in ELA, 33% in math, and 31% in science, compared with state results of 46%, 41%, and 38%. The average shortfall was 8 percentage points in ELA, 8 in math, and 7 in science. The most important takeaway is that both schools were below state results in every all-grade subject.
Derby North leads the latest all-grade comparison, while Derby Middle is lower in all three subjects. North scored 39% in ELA, 33% in math, and 33% in science, ahead of Middle by 2, 1, and 3 percentage points, respectively. Those leads do not put North at the state level: it remains 7 points below state in ELA, 8 in math, and 5 in science. One notable exception is North’s eighth-grade math result: 43%, 3 points above the state’s 40%; Middle scored 38%, 2 points below.
Recent all-grade results declined at both schools in most subjects. From 2024–25 to 2025–26, Middle gained 1 point in ELA but fell 2 in math and 7 in science; North fell 6 in ELA, 7 in math, and 11 in science. The schools’ average gap from the state widened by 4 points in ELA, 7 in math, and 5 in science. SchoolDigger’s statewide percentile ranking also fell, from 64 to 37 for North and from 43 to 32 for Middle. North has a smaller enrollment and a lower student–teacher ratio (14.5 versus 15.8), while Middle’s reported free/reduced-lunch rate is 50% versus 47% at North; North also reports lower chronic absenteeism, 13% versus 18%. These are descriptive differences, not evidence that any one factor explains test results.
