Thayer Academy (TA) is a private, co-educational, college-preparatory day school located in Braintree, Massachusetts, United States. The academy, conceived in 1871 at the bequest of General Sylvanus Thayer, the father of the United States Military Academy, and founder of the Thayer School of Engineering at Dartmouth College, was established in 1877. Thayer annually enrolls approximately 470 students in the Upper School (grades 9–12) and an additional 220 students in the Middle School (grades 6–8). The 34-acre (14 ha) campus is situated in the heart of Braintree and consists of eight buildings and 54 classrooms. Students are drawn primarily from Boston's MetroWest and South Shore communities.
General Thayer, born in Braintree, Massachusetts, graduated as valedictorian from both Dartmouth College and the United States Military Academy at West Point, New York. General Thayer was dedicated to hard work, and at the age of 17, he taught in the local schools of Hanover, New Hampshire to earn money to pay for college – an early sign of the importance he attached to teaching and education. He was Superintendent of the Military Academy at West Point from 1817–1833. General Thayer's 1871 will provided for the creation of Thayer Academy, and on September 12, 1877, the Academy opened its doors to 30 students in what is now Main Building. Glover opened sometime later in 1894. The junior school (grades 5-8), Thayerlands, opened in 1924 and quickly grew to include eight grades as well as kindergarten and nursery school. Beginning in 1969, the lower grades were gradually eliminated, and Thayerlands became Thayer Academy Middle School. Thayer has been a co-educational institution since its founding.
Academic program, students and faculty
Thayer recently completed two state-of-the-art biology labs, a two-story strength and conditioning facility, a new Middle School Resource Center, and four synthetic grass playing fields. In addition, a new Center for the Arts opened its doors in the fall of 2008 and includes a 550-seat theater, dance studios, and art classrooms. Tuition is $35,125 (2011–2012). The school provides $4.9 million in financial aid and is easily accessible from the major surrounding highways: routes 3, I-93, and I-95, and is within walking distance of the Braintree MBTA Red Line rapid transit station.
Total combined enrollment at Thayer Upper and Middle Schools is approximately 690. The Thayer faculty consists of over 100 teachers, and the average class size is between 13 and 16 students.
100% of Thayer graduates matriculate to 4-year colleges and universities. Over 90% of students taking AP exams earn scores of 3 or better and over 60% of Thayer graduates attend colleges and universities listed as "more selective" or "most selective" by Peterson's Guide.
Thayers Traveling Mathlete Team is consistently successful. Often, they win their division, are invited to the regional play-offs, and then continue on to the Massachusetts State Competition. The math team consists of 15 students of all grade levels who meet for practice and travel to area high schools for competitions.
Thayer Academy’s student magazine Voice, published four times per year, was named best scholastic magazine for a school of any size in all of New England by the New England Scholastic Press Association (NEPSA).
In addition, eight Thayer students won Individual Achievement (IA) awards. Over 1,300 entries were received for various IA categories and typically, 10% or fewer entries in any category win recognition.
Voice has two faculty advisors who help students with production questions and ideas. Students are encouraged and expected to display professional journalistic standards and make decisions on their own regarding writing, editing and publishing.
The basic guideline for Voice is that no topic is off-limits. The school administration doesn’t censor the content and all content and editorials are written by students. There is a staff of 18-20 and no single editor.
Green Projects: Grease Lightning
In 2007, with the support of faculty, parents, trustees, and local restaurants, the Advanced Placement Environmental Science (APES) class converted a 1981 Mercedes Benz 300D (diesel) to an environmentally friendly 'green car' that runs on filtered waste vegetable oil.
The class spent a semester installing the conversion kit from Greasecar. The students were divided into teams, some focusing on the build and install, others focusing on the wiring and still another group in charge of the marketing and advertising. "...when Mr. Schneider asked us all if we were interested in making a grease car, ...we thought it would be really, really fun," said Liz Tillotson, a student from Milton, Massachusetts. "We eventually decided to do something that would really stand out and make an impact in the community," said Skip Schneider, the science teacher who supervised the project.
Thayer's athletic teams participate in the competitive Independent School League (ISL), the oldest independent school athletic association in the United States.

High School students are required to participate in 11 terms of interscholastic sports or Health and Wellness classes in order to graduate.
The Thayer Academy campus is equipped with facilities that foster athletic training and performance. On campus, Thayer has ten athletic venues in addition to two gyms and an athletic training room. The Sawyer Athletic center is located in Thayer’s campus center and is home to the athletic department offices, Alumni Gym, Memorial Gym and the hall of fame lobby. The athletic training room is also located in the campus center in the Fish Center for Physical Fitness.
