Summary:
Campbell High School is the only public high school in the Litchfield School District, serving students in grades 9–12 in Litchfield, New Hampshire. The school enrolls about 343 students and has a favorable 11.4-to-1 student-teacher ratio, creating a relatively small-school environment. The district ranks in the 70th percentile statewide and has a four-star rating. Campbell also reports a 94.8% graduation rate and a 0.0% dropout rate, both stronger than New Hampshire averages.
Academic results are mixed, with science and reading standing out more positively than mathematics. In 2025–2026, 47% of students reached proficiency in NH SAS science, nine percentage points above the state, while reading proficiency was 56%, about the same as the statewide 55%. Science improved substantially from 21% the prior year, and 11th-grade science proficiency was also strong at 47%, compared with 40% statewide. Mathematics is the clearest area for improvement: 26% of students were proficient on the NH SAS, 18 points below the state. SAT results show a smaller math gap, but only 26% met the reported benchmark, indicating that families should ask about math support, intervention, and college-readiness preparation.
For parents, the most important takeaway is that Campbell combines strong student completion outcomes with uneven academic performance. Students appear likely to remain enrolled and graduate, but proficiency results suggest that some may need additional help reaching expected mathematics standards. Reading is generally competitive, although Campbell’s 56% SAT reading result was six points below the state. School rankings have also varied considerably, moving from the 76th percentile in 2023–2024 to the 23rd percentile in 2024–2025 and then back to the 63rd percentile in 2025–2026. Because the school is small, yearly results may be affected by changes in individual student cohorts. Overall, Campbell offers a supportive small-school setting with excellent graduation outcomes, strong science performance, and a clear need to strengthen mathematics achievement.
