Summary:
The Merrimack Valley School District has one listed high school, Merrimack Valley High School, serving students in grades 9–12 in Concord, New Hampshire. The school enrolls 744 students and has a student-teacher ratio of 13.8 to 1. Because it is the only high school in the district, there are no school-to-school comparisons; the most useful comparisons are with district and New Hampshire averages.
Merrimack Valley High School has encouraging graduation and student-retention results. Its 2024–2025 graduation rate was 91.2%, higher than the state average of 87.0%, while its dropout rate was 2.0%, slightly below the statewide 2.3%. Reading is the school’s strongest academic area: 57% of students were proficient in 2025–2026, compared with 53% in the district and 55% statewide. The prior year’s reading result was even stronger at 71%, although the recent decline suggests that performance should continue to be monitored.
The biggest concern is academic proficiency in mathematics and science. Only 19% of students were proficient in mathematics, compared with 41% in the district and 44% statewide. Science proficiency was 27%, below the district’s 29% and the state’s 38%. Results declined in all three tested subjects from the previous year, with science falling most sharply, from 46% to 27%. The school’s ranking also dropped from 26th of 86 schools, or the 70th percentile, to 63rd of 89, or the 29th percentile. For families, the overall picture is mixed: the school generally supports students through graduation, but parents should ask about math and science interventions, course performance, attendance supports, and plans to address the recent assessment declines.
