ZIP code 03227 has one elementary school, Sandwich Central School in Center Sandwich, New Hampshire, serving kindergarten through Grade 6. The school enrolls 85 students and is part of the Inter-Lakes Cooperative School District. Its small size and 11.4-to-1 student-teacher ratio may allow for close relationships between students, families, and staff, although results from small student groups can change noticeably from year to year.
