Summary:
Zip code 03253 has three public schools serving students from prekindergarten through 12th grade in the Inter-Lakes Cooperative School District, a relatively small New Hampshire district with 828 students overall.
Inter-Lakes High School is the strongest-performing school in the area and a clear standout for families considering the district. It ranks 23rd out of 89 high schools statewide, placing it in the 74th percentile and earning four stars. The school’s 91% graduation rate is above the state average, and its reported dropout rate is 0%. Reading proficiency is 67% and science proficiency is 50%, both notably above state averages. The high school has also improved its ranking in recent years. Inter-Lakes Elementary School offers a more mixed but improving picture. It ranks in the 50th percentile and recently rose to three stars. Reading proficiency is above the state average, and third-grade students performed particularly well in both math and reading. However, math results decline substantially after third grade, suggesting that sustaining early academic gains is an important priority.
Inter-Lakes Middle School is the main area of concern when comparing the three schools. Its ranking fell from the 66th percentile to the 34th percentile over two years, and its 2025–26 results were below state averages in math, reading, and science. Eighth-grade reading proficiency was especially weak at 34%, compared with 51% statewide, while science proficiency fell to 27%. Parents may want to ask about plans for middle school reading and science support, as well as the transition from elementary to middle school. Overall, the district combines a strong high school, an improving elementary school, and a middle school that may need focused academic attention.
