Maine School Administrative District #35 is comprised of two rural communities, Eliot and South Berwick. Located on the southern Maine border adjacent to Portsmouth, New Hampshire, the communities are able to maintain their rural character, while having access to facilities and technology normally only available in larger urban areas. Neither town has any major industry, although many parents and residents work for high technology companies in adjacent areas. The tax base for both towns is residential rather than industrial.

The district has five schools spanning pre-kindergarten through twelfth grade as well as Adult Education:
 Eliot Elementary School - A PreK-3 school with a student population of approximately 348.
 Central Elementary School - A PreK-3 school with a student population of approximately 482.
 Marshwood Great Works School - A grades 4-5 school with a student population of approximately 350.
 Marshwood Middle School - A grades 6-8 school with a student population of approximately 593.
 Marshwood High School - A grades 9-12 school with a student population of approximately 820.
 Adult Education - Marshwood Adult and Community Education serves the communities of Eliot and South Berwick as well as the entire seacoast area. Programs of study include High School Diploma, GED, Transitions to College, Office Skills and Medical Transcription Certificates as well as a variety of enrichment classes.
