PHA is a PreK-12 public charter school founded in 1996 with the mission to prepare each student for success in college, to inspire a lifelong love of learning, and to foster responsible citizenship. Our school is located on three campuses in Cambridge and Somerville and serves 1,000 students from diverse racial, ethnic, and socio-economic backgrounds. 55% are black (the majority of Haitian origin), 21% are Latino, 12% are white, 9% are Asian, and 3% are of mixed race. Two-thirds are low-income, and nearly half come from homes where English is not the primary language spoken.As a college preparatory school, PHA lives up to its mission: over 95% of PHA graduates matriculate to college, most being the first in their families to do so. PHA has consistently placed in the top 4% of all U.S. high schools per U.S. News & World Report, and Boston Magazine placed PHA among the top ten charter schools in Massachusetts.
