Summary:
ZIP code 03063, in the Nashua area, has two public high schools serving grades 9–12: Nashua High School North and Academy for Science and Design Charter (H), offering families a choice between a large traditional high school and a smaller science- and technology-focused charter school.
Academy for Science and Design Charter (H) is the clear academic standout. It ranked first among New Hampshire high schools for three consecutive years and earned a 99th-percentile standing in 2025–2026. The school reported proficiency rates of 93% in mathematics, 100% in reading, and 86% in science, along with a 90.3% graduation rate and a 0% dropout rate. Its smaller enrollment of 264 students and specialized academic model may appeal to families seeking a focused, high-performing environment. The school is part of the Academy for Science and Design Charter School district.
Nashua High School North is much larger, enrolling 1,543 students, and offers the broader setting associated with a traditional comprehensive high school. However, its 2025–2026 results were considerably weaker: 18% proficiency in mathematics, 53% in reading, and 31% in science. It ranked 67th of 89 schools, down from 41st three years earlier, while its graduation rate was 82.7% and dropout rate was 3.1%. Mathematics is the most urgent concern, and reading has also declined recently. Families should also consider that the schools serve different student populations and have different enrollment sizes, so test-score comparisons do not capture every difference in the educational experience. Nashua School District operates Nashua North.
