Summary:
Hollis-Brookline Cooperative School District includes two schools serving grades 7–12: Hollis-Brookline Middle School for grades 7–8 and Hollis-Brookline High School for grades 9–12. Together, they enroll 1,114 students, and the district ranks 16th out of 166 districts statewide, placing it around the 90th percentile with a five-star rating.
Both schools perform well above New Hampshire averages, but they have different strengths. Hollis-Brookline High School is especially strong in reading, with 88% of students proficient on both the latest state assessment and the 11th-grade SAT, compared with 55% and 62% statewide. It also reports a 95% graduation rate and a 0% dropout rate. Mathematics remains solid at 59% proficiency, while science is weaker at 50% and declined from the prior year. The high school ranked 10th among 89 schools, keeping it among the state’s highest-performing high schools despite some year-to-year ranking fluctuation.
Hollis-Brookline Middle School shows the strongest recent improvement. Its ranking rose to 8th out of 138 schools, and proficiency increased to 67% in mathematics, 75% in reading, and 66% in science. Science showed the largest gain, improving 25 percentage points in one year; mathematics rose 10 points and reading 8 points. The middle school slightly exceeds the district average in mathematics and is particularly strong in science, while reading is four points below the district average but still well above the state result. Families will find strong academic performance at both levels, with the main issues to watch being high-school science and mathematics, and whether the middle school’s recent gains continue as students move into high school.
