Best Schools in Nashua, New Hampshire

Nashua's public school system spans 22 ranked schools, from elementary grades through high school, with an average rating of 5.7 out of 10. That average is serviceable, but the spread matters more than the mean: only 3 schools — 14% of the ranked total — score 7 or above, which means strong options exist but aren't evenly distributed across the city.

The standout is Academy for Science and Design Charter High School, rated 8.1 out of 10 and the highest-scoring school in Nashua. It's a charter, so enrollment isn't automatic — families need to track application windows and lottery timelines. At the elementary level, Bicentennial and Charlotte Ave each score 7.2 out of 10, giving parents of younger children two competitive options to compare directly. Birch Hill Elementary (6.8) and Nashua High School South (6.8) round out the top five, both landing above the city average.

For families with elementary-age children, the school assignment question is urgent. Bicentennial and Charlotte Ave both sit 1.5 points above the city mean, a real performance gap, but attendance zones in a city this size typically determine placement automatically. Confirming your home address's assigned school before settling on a neighborhood is one of the highest-leverage moves a parent can make here.

Parents evaluating high school options face a clear decision: the charter path through Academy for Science and Design (8.1) or the traditional route through Nashua High School South (6.8). A 1.3-point gap on a 10-point scale is significant. If the charter's program matches your student's interests and the application timeline is workable, it's the strongest academic option in the city by the data. If charter enrollment doesn't come through, South still outperforms the city average and functions as a solid default. Either way, understanding the charter application process early gives Nashua families the most options.
