Summary

Jefferson Marine Science Elementary School is a PK–5 school in Norwalk, CT, serving 457 students within the Norwalk School District. After several years near the bottom of Connecticut's elementary school rankings, Jefferson climbed to 298th out of 491 schools statewide (39th percentile, 2 stars) in 2025–2026 — a major jump from 426th place just two years earlier.

The school's recent gains are broad-based. From 2024–2025 to 2025–2026, 5th grade ELA proficiency jumped from 36.0% to 54.3%, exceeding the state average, while 4th grade math rose from 24.3% to 47.6% and 3rd grade math from 31.9% to 45.9%. Science proficiency also climbed to 47.1%, and chronic absenteeism fell from 18.9% to 13.1% — better than both district and state averages. Jefferson outranks its closest neighbors, Kendall College & Career Academy (433rd) and Tracey Magnet School (350th); in 3rd grade math, Jefferson's 45.9% proficiency compares to just 12.5% at Kendall and 20.0% at Tracey. Hispanic students have shown exceptional subgroup progress, jumping from the 21st to 71st percentile statewide over two years.

Challenges remain. Male students continue to lag behind female students (15th vs. 31st percentile statewide), and 5th grade math (32.9%) and science (47.1%) still trail state averages. Jefferson spends less per student ($17,428) than Marvin Elementary School ($19,506) and Fox Run Elementary School ($18,466), while serving a population where 64.55% of students qualify for free/reduced lunch. If the school sustains its momentum and narrows the gender gap, it is well-positioned to keep climbing the state rankings.

Excellent school, no complaints about it. Very science focused- Lots of programmes and collaborations from various companies - eg GE science classes. My 2 kids had a good time here. Lots of field trips/ activities to places like maritime, stepping stones etc. Very good teachers, they have been very patient with the kids. It was blue ribbon winning school 2015-16 and a US bronze health winner this year 2016. Close Quote
