Summary
Assabet Valley Vocational High School in Marlborough, MA, is a public vocational-technical high school serving grades 9–12 with 1,144 students in the Assabet Valley Regional Vocational Technical district. On Assabet Valley Vocational High School’s own rank history, it was 230th of 353 in 2025–2026, placing it in the 35th percentile with 2 stars; the district summary is less favorable. It peaked at 134th of 348 in 2016–2017 and has generally ranked in the 35th–49th percentile since 2018–2019. Its strongest outcome is completion: a 98.5% graduation rate and 1.5% dropout rate in 2024–2025. Core MCAS proficiency is weak: 34.55% in ELA, 34.18% in Math, 28.52% in Science, and 21.95% in Biology in 2025–2026. Physics is a striking exception at 95.83% proficient, versus a state rate of 46.58%. The school spends $20,484 per student and has a 10:1 student-teacher ratio.
Core proficiency sits near the bottom of nearby schools, clustering with Clinton Senior High and Marlborough High, and far below Westborough High, Algonquin Regional High, Lincoln-Sudbury Regional High, Tahanto Regional High, and Advanced Math and Science Academy Charter School. Yet Assabet graduates more students than Westborough High, Nashoba Regional, Marlborough High, Clinton Senior High, Maynard High, and Hudson High, and its dropout rate is lower than most of those schools. Its $20,484 per-student spending and 10:1 ratio are better-resourced than most peers, but that has not produced comparably strong core MCAS scores. Physics remains the clear standout.
The takeaway is that Assabet is stronger at completion than at core academic proficiency. Its vocational model appears to keep students engaged, even as ELA, Math, Science, and Biology results lag the state and nearby districts. Physics is a signature strength, while Biology and Science are weak spots. Subgroup effectiveness varies: Special Education students are a consistent strength, ranking in the 80th percentile or higher with 4 stars in 2023–2024, 2024–2025, and 2025–2026; female students and low-SES students rank lower or have declined. Overall, Assabet occupies a distinct niche: not academically comparable to high-performing neighbors on core MCAS, but with stronger graduation and dropout outcomes than Clinton Senior High, Marlborough High, Hudson High, and Maynard High.
