Summary:
Regional School District 16 is home to one middle school, Long River Middle School, serving grades 6–8 in Prospect, CT, with an enrollment of 434 students. Because this is the district’s only middle school, its performance directly reflects the district’s overall standing, and the district ranks 27th out of 153 in Connecticut. Long River Middle School stands out as a high-performing school, ranked 49th out of 258 middle schools statewide (81st percentile) with a 4-star rating for the 2025–2026 school year.
Long River consistently outperforms Connecticut state averages across every subject and grade level. In 2025–2026, the school posted proficiency rates of 54.6% to 73.7% in ELA, 59.0% to 64.7% in math, and 71.7% in 8th grade science, compared to state averages of roughly 51%, 42–44%, and 51% respectively. The school’s chronic absenteeism rate is exceptionally low at 4.3%, versus 16.4% statewide, indicating strong student engagement and a positive school climate. The school has also improved its state rank steadily over three years, climbing from 81st to 60th to 49th.
However, not all results are uniformly improving. While 8th grade ELA and math saw strong year-over-year gains of 11.5 and 12.5 points, 6th grade ELA and 7th grade math declined. These early-middle-school subjects appear to be relative weak points compared to the upper grades, with 6th grade ELA at 54.6% and 7th grade math at 59.0% in 2025–2026. Notably, about 29.7% of students qualify for free or reduced-price lunch, yet the school still achieves top-quartile results. Overall, Long River Middle School is a strong, improving school that clearly exceeds state averages, with its low absenteeism and rising rank being especially encouraging for parents seeking a well-rounded middle school experience in Regional School District 16.
