Phillips Academy is a private, coeducational boarding and day school in Andover, Massachusetts, founded in 1778 by Samuel Phillips Jr., who drafted its founding constitution. The institution enrolls 1,169 students drawn from 41 U.S. states and territories and 53 countries, and it employs 244 faculty members. Its stated purpose is to educate young people in both knowledge and character, in keeping with the founding ideal of "non sibi" (not for self).
The academic programme runs to more than 300 courses, including 8 world languages and 150 electives, delivered in classes averaging 13 students against a student-faculty ratio of 7:1. Beyond the classroom, the Academy fields 67 interscholastic teams across 23 sports and supports arts instruction and physical education; the 70,000-square-foot Pan Athletic Center was funded from the endowment. Summer and outreach programmes serve close to 1,000 further students each year.
The Academy is supported by an endowment of $1.47 billion, which underwrites financial aid received by 47% of students, as well as continuing investment in facilities and educational innovation. The community is characterised by its commitment to diversity and inclusion, and by an expectation that students and adults alike respect, inspire and learn from one another.
