Educational Philosophy

We, the members of the SAU 21 educational community, are committed to developing life long learners who are creative and critical thinkers and who contribute to a changing global society. The SAU 21 educational community consists of students, teachers, parents, administrators, school board members and the community-at-large working collaboratively towards this mission.


Our coastal location offers wonderful venues for the arts, history, healthy lifestyles, and access to distinctive environmental and educational resources. Our proximity to Boston and the University of NH provides extended learning opportunities for our teachers, students and community. Welcome to SAU 21!  

District Professional Learning Goal

SAU21 Districts will develop a fully-aligned competency-based curriculum across disciplines by collaborating and communicating with stakeholders as measured by completed common assessments, rubrics, and reporting tools to advance student learning within a growth model by June, 2020.
