St. Mark’s is a four-year, college preparatory, boarding and day school located 20 miles west of Boston. Originally founded in 1865 as an Episcopal boys’ school, St. Mark’s merged with the Southborough School for Girls in 1977. Our classes are traditionally referred to as forms: 9th grade is III Form, 10th grade is IV Form, 11th grade is V Form, and 12th grade is VI Form.
Students will gain the necessary skills to be successful in a collegiate setting. Our younger students begin with basic skills and move on to higher order skills development as they advance through the curriculum. They enhance their ability to master developmentally appropriate skill sets such as critical/analytical thinking, logical argumentation, effective writing, and close observation. Students are exposed to a foundational core curriculum designed to sharpen skills and habits of mind upon which to build their secondary school and college careers.
