Schools in Zip Code 06340

Zip code 06340 in Groton, Connecticut includes 7 schools — 3 elementary, 1 middle, and 3 high — enrolling about 3,999 students across the Groton School District, Connecticut Technical Education and Career System, and LEARN consortium. Most students come from low-income households; the estimated weighted free/reduced-price lunch rate is 64%, ranging from 30.7% at Marine Science Magnet High School to above 80% at Groton Middle School and Catherine Kolnaski Magnet School.

The academic standout is Marine Science Magnet High School, ranked 23rd of 141 Connecticut high schools with 77.8% SAT ELA proficiency, 77.4% science proficiency, and a 98.4% graduation rate. Robert E. Fitch High School, the area's largest, is near state averages in ELA and science and has improved its ranking, but chronic absenteeism of 25.4% is a concern. Ella T. Grasso Technical High School graduates 98.7% of students but only 9.1% reach proficiency in SAT Math. Among elementary schools, Catherine Kolnaski Magnet School leads with 66.1% 5th-grade science proficiency despite its 80.3% poverty rate, while Thames River Magnet School posts strong 5th-grade ELA and math scores.

The biggest vulnerability is secondary math; even Marine Science posts just 49.2% SAT Math proficiency. Science is a clear strength across multiple schools. All three high schools exceed the state's 91.2% graduation rate, though Grasso's high completion coexists with weak test scores. Chronic absenteeism ranges from 9.4% at Charles Barnum Magnet School to 25.4% at Fitch, yet Barnum's strong attendance does not translate into achievement — its 4th-grade ELA proficiency is just 32.8% versus 50.9% statewide. District rankings can be misleading: the Groton School District sits in the 31st percentile, but school-level rankings span from the 36th to the 84th percentile.
