Summary

Jefferson Marine Science Elementary School is a public magnet elementary school in Norwalk, Connecticut, serving grades PK-5 with a total enrollment of 465 students. The school is part of the Norwalk School District, which is ranked 118 out of 156 districts in the state.

Despite the school's focus on marine science, it has consistently ranked in the bottom half of Connecticut elementary schools, with proficiency rates on standardized tests well below the district and state averages across all grade levels and subject areas. For example, in the 2024-2025 school year, only 29.2% of 3rd graders, 35.7% of 4th graders, and 36% of 5th graders were proficient or better in English Language Arts, compared to 46.9%, 51.4%, and 52.5% at the state level, respectively. Similarly, in mathematics, only 31.9% of 3rd graders, 24.3% of 4th graders, and 30.3% of 5th graders were proficient or better, compared to 52.2%, 51.4%, and 44.9% at the state level.

The school's challenges may be related to its high percentage of students from low socioeconomic backgrounds, with 67.74% of students qualifying for free or reduced-price lunch in the 2023-2024 school year. Additionally, the school has a relatively high percentage of English Language Learner (ELL) students, who ranked 5th out of 6 Connecticut elementary schools in the 2022-2023 school year. Despite the school's relatively low student-teacher ratio and high per-student spending, it has also struggled with high chronic absenteeism rates, ranging from 17.2% to 19.8% over the past few years, which is significantly higher than the state average.

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
