Greater Lowell Regional Vocational Technical has the best graduation rate (98.6%) and lowest dropout rate (0.4%), and its rank improved from 44th to 57th percentile. However, its ELA 10th (37.23% vs. 45.48% state) and Physics EOC (27.27% vs. 46.58% state) lag. Innovation Academy Charter School shows strong 10th-grade and end-of-course results—ELA 51.32%, science 50.82%, biology 46.58%—but weaker all-grade and middle-school results (e.g., 7th math 17.89% vs. 37.48% state). It has the lowest graduation rate (94.7%) and highest dropout rate (2.1%).
Interestingly, higher spending and lower student–teacher ratios do not guarantee better outcomes here. Tyngsborough High School has the lowest per-student spending ($15,962) and highest student–teacher ratio (12.8) yet the strongest overall profile. Greater Lowell Regional Vocational Technical spends the most ($21,740) but has mixed test scores. Tyngsborough High School’s ELA 10th proficiency fell from 61.06% in 2024–25 to 45.33% in 2025–26, a larger drop than the state’s decline from 50.66% to 45.48%. Free/reduced lunch data is not reported for any school, so socioeconomic context is missing; any conclusions about school effectiveness should consider that limitation.
