Summary
Marblehead High is a 9–12 high school in the coastal town of Marblehead, MA, serving 861 students, and it remains one of the state's strongest comprehensive high schools. In 2025–2026 it ranked 92 of 353 schools statewide — the 74th percentile — and earned 4 stars, a rating it has held every year in the data shown. Completion outcomes are excellent: a 99.2% graduation rate and a 0.0% dropout rate in 2024–2025, better than the Marblehead district's 97.6% graduation rate and 0.0% dropout rate. Historically, graduation has stayed between 96.7% and 99.2%, with dropout never higher than 1.9%.
Test scores remain above both the district and the state, though the margin has narrowed. In 2025–2026 MCAS Next Generation results, Marblehead High posted 49.47 in 10th-grade ELA (district 47.72, state 45.48), 58.64 in 10th-grade Mathematics (state 43.73), 51.87 in 10th-grade Science (state 40.50), and 55.50 in Biology end-of-course (state 37.68) — an advantage of +17.82 points in Biology and +14.91 in Mathematics. Those results have fallen broadly since 2022–2023, when ELA 10 was 80.70 and Math 10 was 78.32. Among nearby schools, Swampscott High outperformed Marblehead High in every reported 2025–2026 subject and ranks higher overall at 55 of 353 (84th percentile), while Marblehead High sits clearly ahead of Salem Academy Charter School, Salem High, Lynn Vocational Technical Institute, and Lynn English High.
Staffing and spending are moderate rather than extreme. Marblehead High reported 10.7 students per teacher in 2024–2025 — lower than Swampscott High (11.6), Lynn Vocational Technical Institute (12.1), and Lynn English High (15.0) — and per-student spending of $17,787 in 2020–2021, above Swampscott High at $17,420 but well below Salem High at $22,540. Effectiveness for special education students is a relative strength, holding at 69 of 298, 77th percentile, 4 stars in 2025–2026 and 83rd percentile the year before. Low-income student effectiveness was 68th percentile, 3 stars in 2025–2026. Overall, Marblehead High remains a high-performing 4-star school with excellent completion outcomes; the main recent concern is its broad proficiency decline, which has also eased some subgroup rankings.
