Founded in 1969 as Saint Thomas Aquinas High School, Bishop George Ahr High School is a private, coeducational college preparatory school of the Roman Catholic Diocese of Metuchen. The school resides on a thirty-six acre section of land in the northern section of Edison Township in the state of New Jersey.

After the formation of the Diocese of Metuchen, the school was renamed in 1984 to honor its founder: Bishop George Ahr. To address increasing enrollment and the desire to maintain cutting-edge offerings, Bishop Ahr High School underwent a capital expansion that opened in January 2006 and included new classrooms, a video studio, two computer labs, a second gym, a weight room, server space, and other academic facilities.

Bishop George Ahr High School’s enrollment is open to young men and women of all faiths. It does not discriminate on the basis of race, color, national origin, sex, or creed in the administration of its educational, admission or financial policies, activities, athletics, or any school-sanctioned program. However, as Bishop George Ahr High School is a Catholic institution, all students, regardless of background, are required to complete our religious curriculum and participate in worship services.

Bishop George Ahr High School has a diverse population of students hailing from over 60 districts, primarily from Middlesex, Monmouth, Somerset and Union Counties. It also has a global reach, and consistently welcomes international students.

A knowledgeable and dedicated team of religious and lay administration, faculty and staff collaborate with a large community of parents, alumni and benefactors to provide a quality Catholic education.

In October of 2014, Bishop George Ahr High School received full re-accreditation through AdvancEd, the parent organization of the North Central Association Commission on Accreditation and School Improvement.
