The school has approximately 900 students and serves the communities of Andover, Boscawen, Loudon, Penacook, Salisbury, and Webster.

The faculty, staff, students, and community began self-study for reaccreditation in 2009; the next visiting team came in 2011. In 2003, the school was recognized by the New Hampshire Excellence in Education award (EDies) for being the best high school in the state of New Hampshire.
