Summary

John S. Martinez Sea and Sky STEM School is an elementary school serving grades PK-8 in the New Haven School District in Connecticut, with 483 students enrolled.

The school faces significant challenges in terms of academic performance, with consistently low rankings among Connecticut elementary schools and proficiency rates well below state and district averages in subjects like English Language Arts, math, and science. For example, in 2024-2025, only 24.4% of 4th graders were proficient in ELA, compared to the state average of 51.4%. The school also struggles with high chronic absenteeism rates, ranging from 17.7% to 37.5% over the past few years.

While the school serves a high percentage of economically disadvantaged and Hispanic students, its performance lags behind nearby magnet schools like Celentano BioTech Health and Medical Magnet School and Worthington Hooker School, as well as the local Booker T. Washington Academy, which serve similar student populations but achieve significantly better academic outcomes.
