Cornerstone School

The Cornerstone School was incorporated in December 1985 as a non-profit organization with the goal of meeting the growing need for a non-traditional private preschool and elementary experience in the seacoast region in New Hampshire. Parents of Montessori students immediately joined to establish the school and continued to work in support of the school's mission.

Although we have enjoyed rapid growth, we are committed to a school which is small enough to maintain a feeling of community. Ultimately, we hope to house approximately 140 students in the facility at High Street. This number will allow diversity within both the student body and faculty. Thus we can maintain individual attention and foster the development of each child in our care. Private Schools in New Hampshire are regulated by the New Hampshire Department of Education, and must meet minimum standards as specified in the New Hampshire Code of Administrative Rules Chapter ED 400. There are currently 289 private schools in New Hampshire.

A school must meet two requirements to be defined as a private school in New Hampshire. An individual or group not associated with the state must establish the private school, and officials who have not been publicly elected or appointed must conduct the schools operations.

Private schools who apply for approval in New Hampshire must write a letter of intent stating the private schools educational purpose, objectives and beliefs. A copy of the curriculum for the private school must also be provided.
