Summary

Mystic River Magnet School is an elementary school serving grades PK-5 in the Groton School District in Mystic, Connecticut, with 511 students. While the school has consistently ranked in the bottom half of Connecticut elementary schools, receiving a 2-star rating from SchoolDigger, a closer look at the data reveals some interesting insights.

Academically, Mystic River Magnet School's performance, as measured by SBAC test scores, is generally below the Groton School District and Connecticut state averages. For example, in 2024-2025, the school's 3rd grade English Language Arts proficiency rate was 37%, compared to 42.6% for the district and 46.9% for the state. The school's 5th grade Math proficiency rate was also lower at 34.5%, compared to 47% for the district and 44.9% for the state. Additionally, the school's performance for its White student subgroup is particularly concerning, ranking in the bottom quarter of Connecticut elementary schools for this group in recent years.

Interestingly, Mystic River Magnet School's performance lags behind other magnet schools in the Groton School District, such as Thames River Magnet School and Northeast Academy Magnet School, which have higher academic proficiency rates, higher SchoolDigger rankings, and lower chronic absenteeism rates. This highlights the significant variation in performance among the magnet schools in the Groton and New London districts.
