About Us

The Hosmer School is built on land once owned by the Hosmer family in the east end of town. Alfred Hosmer (1832 – 1891) was a physician, historian, and founder of the Watertown Historical Society. Dr. Hosmer was also the chairman of a fundraising campaign that helped to build the first Watertown Public Library. As schools became overcrowded a school was built and named in honor of Dr. Alfred Hosmer and his uncle Dr. Hiram Hosmer. Ms. Harriet Hosmer, daughter of Hiram and cousin of Alfred gave a speech at the opening ceremony for the school.

The current Hosmer School building was rebuilt in 1967. The Hosmer School has approximately 600 students from very diverse backgrounds.  Over two dozen languages are represented in our school and we are proud of our inclusive practices.  We have very active and involved parents and hold many events throughout the school year that creates a real sense of community.

Mission Statement

The Hosmer School provides an active, versatile, and challenging learning environment which helps each student develop to their fullest academic, social, physical, and emotional potential. We aim to foster individual responsibility and to develop understanding of others, the community, and the world. We promote a cooperative and interactive partnership between the school and the home.
