Summary

Mystic River Magnet School is an elementary school (PK–5) in Mystic, CT, serving about 520 students as part of the Groton School District. The district itself is ranked 105th out of 153 Connecticut districts, and Mystic River currently holds a 2-star rating, ranking 316th out of 491 elementary schools statewide. That ranking has slipped from the 45th percentile four years ago to the 36th percentile today. On a positive note, the school maintains a favorable student-teacher ratio of 11.9-to-1.

Academic performance lags behind nearby schools. In 5th-grade math, only 34.3% of Mystic River students are proficient, compared with 68.3% at Northeast Academy Magnet School and 70.7% at Deans Mill School. In 5th-grade English Language Arts, 41.8% are proficient, about 27 points below Northeast Academy and 29 points below Deans Mill. The one relative bright spot is 5th-grade science, with 47.8% proficient, close to the state average of 52.9%. Even Charles Barnum Magnet School, which carries a similar overall state rank, outperforms Mystic River in 5th-grade math.

The school's most pressing challenges are economic and attendance-related. The share of students eligible for free or reduced-price lunch jumped from 43.6% to 81.4% in just two years, a dramatic shift that is now comparable to high-poverty schools in the region. Chronic absenteeism is 17.3%, the highest among Groton's magnet elementary schools and far above Northeast Academy's 6.9%. There are positives to build on, though: low-income students perform near the state median, and the favorable class sizes give teachers a solid foundation. Improving attendance will be the clearest lever to help more students succeed.
