Summary:
Peterborough, New Hampshire, has one school in this list—Lionheart Classical Academy Chartered Public School—a small K–8 public charter school serving 311 students with a 15.2-to-1 student-teacher ratio.
For parents, the school’s overall academic results are mixed but generally close to New Hampshire averages in mathematics and reading. In 2025–2026, 45% of students were proficient in mathematics compared with 44% statewide, while 54% were proficient in reading compared with 55% statewide. Reading is a particular strength in the upper grades: proficiency reached 61% in Grade 6, 75% in Grade 7, and 56% in Grade 8, all above state averages. Grade 7 stands out most, with results 15 percentage points above the state in mathematics and 18 points above the state in reading.
Performance is less consistent in the lower and middle grades. Reading proficiency was below the state in Grades 3 and 4, and mathematics lagged in Grades 4, 5, and 8. Science is the clearest area for improvement: only 25% of students were proficient, compared with 38% statewide, including just 19% of fifth graders. The school did make encouraging year-over-year gains in mathematics, which rose 6 points, and reading, which rose 11 points; science declined by 8 points. The school’s reported 2-star rating and 35th-percentile ranking suggest that families should look beyond the overall ranking and examine individual grade and subject results. In summary, Lionheart Classical Academy Chartered Public School appears strongest in upper-grade reading and Grade 7 academics, while foundational reading, uneven mathematics results, and especially science deserve careful consideration.
