Summary:
Phoenix Academy Charter Public High School Chelsea is the only high school in the Phoenix Academy Charter Public High School Chelsea (Distric district, serving grades 9–12 with 198 students in Chelsea, Massachusetts. Because it is the sole school in this district, there are no local peer schools to compare it against; the most useful benchmarks are its own history and the Massachusetts state averages reported alongside its test scores.
Rankings tell a dramatic story. In 2017–18 the school ranked 6th out of 345 schools, placing in the 98th percentile with 5 stars. By 2018–19 it had fallen to 312th of 351, the 11th percentile with 1 star, and in 2025–26 it ranked 341st of 353, the 3rd percentile with 0 stars. The district overall ranks 349th of 351, in the 1st percentile with 0 stars. There is a long gap between the 2018–19 and 2025–26 records, so this should not be read as a continuous yearly trend.
Current outcomes are low. In 2024–25 the graduation rate was 12.3% and the dropout rate 58.9%. MCAS Next Generation proficiency in 2025–26 ranged from 0% in 10th-grade English Language Arts to 11.76% in 10th-grade Science, against state averages of 45.48% and 40.5%. Mathematics was 5.56% (state 43.73%) and Biology End of Course 4.55% (state 37.68%). School and district figures are identical in every reported test score. The student-teacher ratio was 19.9 in 2024–25, and per-student spending was $21,496 in 2020–21. Free/reduced lunch data is blank, and spending data is several years old, while there are gaps in the rank history — so these figures describe reported outcomes but cannot by themselves explain them.
