Summary
Martha's Vineyard Charter Public School is a small public charter school in West Tisbury, MA, serving grades K–12 with 176 students, and it operates as its own district, Martha’s Vineyard Charter Public School (District); because it sits on Martha’s Vineyard with no other schools within 20 miles, this summary compares its results to state MCAS averages and its own past performance rather than to nearby schools.
In MCAS results, the school’s profile splits sharply by subject. ELA has been above the state every year shown, though the advantage narrowed from +11.18 points in 2022–23 to +6.22 points in 2025–26. Math has been below the state every year, with the gap widening to -13.66 points in 2024–25 and then narrowing slightly to -12.16 points in 2025–26. Science was above the state each year, often by a wide margin, but its margin collapsed to +1.33 points in 2025–26. Civics has been a consistent relative strength, while Biology EOC was a weak spot in 2025–26 (28.57 vs. state 37.68). Grade-level results vary widely: 8th grade math, science, and civics were all above state in 2025–26, but 4th grade ELA and 3rd, 4th, and 6th grade math were far below state. With roughly 13–14 students per grade, a few students can swing these percentages dramatically.
High school completion looks excellent in the most recent year: 100% graduation and 0% dropout in 2023–24. However, prior years were volatile, with dropout rates of 22.2% in 2022–23 and 25.0% in 2020–21, so this should be watched over multiple cohorts before being treated as a stable trend. Resources are notable: the student–teacher ratio was 7.5 in 2024–25, down from 8.9 in 2022–23, and per-student spending was $35,079 in 2020–21. Free/reduced lunch data was not reported for recent years, so socioeconomic context is unavailable. Overall, this is a small, resource-intensive K–12 charter school with relative strengths in ELA, science, and civics, persistent math weakness, and highly variable outcomes by grade and year.
