Located next to Braintree's historic district and just up the hill from the MBTA's final Red Line stop is the historic 34-acre campus of Thayer Academy. Since 1877, our coeducational day school for grades 6-12 has been an enabling and ennobling environment where each student is affirmed, supported and challenged to take on responsibilities, ambitions, and achievements. 

In the Upper School, we inspire our students to pursue excellence in a number of areas: character, academics, arts, and athletics. Students learn in a challenging academic environment, and there are honors and AP courses in most disciplines. All of our courses demand that students develop sills in creative problem solving, critical analysis, and independent thinking. These are the skills that enable our students to succeed in college and in life.
