Accredited by the Middle Atlantic States Association of Secondary Schools, and the Commonwealth of Pennsylvania, Unionville High School has received state recognition for excellence and high achievement in the preparation of students for higher education.

[2] Unionville has a 1:14 teacher-to-student ratio,[3] allowing it to offer a wide range of both core and elective classes for its students.

Its core departments- English, Social Studies, Math, and Science- are based on a four-tier system in order to allow for the variety of student capabilities, from First Level and Academic classes to Honors and Advanced Placement ; in an attempt to broaden its curriculum, the school recently began to offer differentiated classes within those tiers, such as a choice between an American Literature Survey and Contemporary Young Adult Fiction for 11th grade Academic English students.

[5] Unionville employs a six-member full-time counseling staff,[7] much of whose time is spent on the college application process, including meeting with every junior and senior at least once per year to determine their post-secondary educational needs and how the office can best facilitate them;[7] 94% of graduating seniors in 2008 are currently attending college, 96% of which are four-year institutions.

[9] Unionville High School has a total of 72 registered clubs, representing approximately one club for every 20 students and including five intra-school academic competition teams, such as Debate Team and Future Business Leaders of America, four honor societies, and several national and international organizations, such as Amnesty International and Habitat for Humanity, and the Bocce Club and the Unionville Signers, which promote sign language education.
