of 492 Connecticut Elementary Schools

Better than 8% of Connecticut elementary schools

Summary

Gilmartin School is a public PK–8 school in Waterbury, CT, serving 462 students from predominantly low-income families (80% eligible for free/reduced-price lunch) under the Waterbury School District. Located on Wyoming Ave., the school has historically ranked in the bottom 10% of Connecticut elementary schools, but it has shown steady improvement, climbing from the 1st percentile in 2022–2023 to the 8th percentile in 2025–2026.

The most encouraging news for parents is attendance. Chronic absenteeism has plummeted from 39.8% in 2021–2022 to just 14.6% in 2025–2026—now better than the district average (23.1%) and the state average (16.4%). By comparison, nearby Duggan School (25.3%), Woodrow Wilson School (29.8%), and B.W. Tinker School (25.7%) all have significantly higher absenteeism. Only two nearby schools do better: Maloney Interdistrict Magnet School (6.2%) and Roberto Clemente International Dual Language School (6.0%).

Academically, however, proficiency rates remain below district and state benchmarks. For example, 3rd grade ELA proficiency was 17.8% in 2025–2026, versus 21.8% for the district and 47.3% statewide. There are bright spots in upper grades: 7th grade math outpaced the district average (17.8% vs. 14.9%), and 6th grade ELA nearly matched it. Spending per student (~$15,420) and student-teacher ratio (14.6) are mid-range compared with neighbors. Gilmartin is not the lowest-performing school in the area—it outranks Woodrow Wilson and Hopeville School—but it lags far behind the magnet schools, which achieve two to three times higher proficiency. Still, the improved attendance and three consecutive years of rising rankings offer a foundation for future gains.

What people are saying

by a parent
Thursday, January 24, 2019

I cannot day enough about a handful of teacher in that school. They are amazing.

But administration, and many other teachers are not easy to work with. They teach and discipline in a cookie cutter fashion leaving no room for the creative child, and definitely no room for the concerned parent. As a parent I feel alienated, I feel I’m unable to speak up out of repercussions on my children. I’ve tried talking, meetings and going down town but in this city you get nowhere. I’m counting down the days until my children are out of the Waterbury school system. Close Quote
