Located next to Braintree's historic district and just up the hill from the MBTAês final Red Line stop is the historic 34-acre campus of Thayer Academy. Since 1877, our coeducational day school for grades 6-12 (Middle School, grades 6-8; Upper School, grades 9-12) has been an enabling and ennobling environment where each student is affirmed, supported, and challenged to take on responsibilities, ambitions, and achievements. Thayer continues to be a place where tradition and innovation meet, and where students form lifelong relationships with one another and with inspiring teachers who care deeply about their students'_ personal growth and academic success.
