Holy Trinity School


Holy Trinity School exists to communicate Gospel values, to provide a quality academic program and to develop a faith community which encourages respect for self, others, and the global community.    


Holy Trinity School began educating the children of Wallingford and surrounding towns in 1913 and, ever since, a Sister of Mercy has provided educational leadership. Christian values and moral principles are not merely taught; they are lived throughout our school days.

Our curriculum includes daily religious education along with a strong language arts and mathematics program. Other updated features such as a fully electronic library, state-of-the-art technology center, advanced math program, Spanish, and an instrumental music program enhance the curriculum. Interactive Smart Boards are used in all classrooms.  Holy Trinity School is accredited by the New England Association of Schools and Colleges.

Our school day runs from 8:10 a.m. until 2:25 p.m.  Transportation is provided for students residing in Wallingford.
