Summary
Mill Falls Charter School is a small public charter school in Manchester, NH, serving 168 students in kindergarten through grade 6 in an area surrounded by other Manchester schools, including Green Acres School less than a mile away. The school ranks 92nd out of 230 New Hampshire schools, placing it at the 60th percentile and earning three stars. That makes it a solid local option and a higher-ranked school than most nearby schools in the Manchester School District, though it trails the nearby Auburn Village School, which ranks in the 80th percentile.
Reading and science are the clearest strengths. Overall, 63% of students are proficient in reading, compared with 55% statewide, while science proficiency is 54%, well above the 38% state average. Reading is especially strong in grades 4–6: fourth-grade proficiency reaches 74%, with fifth and sixth grades at 71% and 64%. Science has also improved substantially, rising from 29% in 2023–24 to 54% in 2025–26. Mathematics is more uneven: 42% of students are proficient, close to the 44% state average, but results are weaker in grades 3, 4, and 6. In comparison, Polaris Charter School has stronger mathematics results, while Mill Falls performs about the same in reading and much better in science.
For families, the main academic question is whether the school can improve mathematics while maintaining its strong reading and science results. Mill Falls’ recent rankings have fluctuated, and its current position is below the stronger results it posted in 2017–19. The school also reports a 24:1 student-teacher ratio—much higher than Polaris, Auburn Village, and nearby district schools—which may be worth asking about when considering class size, individual attention, and intervention support. Overall, Mill Falls stands out as a comparatively strong Manchester-area choice, particularly for upper-grade reading and science, but families should look closely at mathematics support and how the school addresses uneven year-to-year results.
