Summary

School 21 is an elementary school in Yonkers, NY, serving 306 students in grades PK-6. It is part of the Yonkers City School District, which is ranked 663 out of 874 districts in New York and has a 1-star rating from SchoolDigger. Over the past 10 years, School 21 has consistently ranked in the bottom half of New York elementary schools, with a 1-star rating for most years.

School 21's student performance on state assessments is generally lower than the Yonkers district and New York state averages across English Language Arts, Math, and Science. For example, in 2024-2025, only 51.92% of 3rd graders at School 21 were proficient in ELA, compared to 48.59% for the Yonkers district and 54.15% for New York state. The performance gap is particularly wide in Math, where School 21's proficiency rates trail the district and state by 5-10 percentage points across grade levels. The school's performance on Regents exams is also below the Yonkers district and New York state averages.

Interestingly, the nearby Las Hermanas Mirabal Community School, Montessori School 27, and Pearls Hawthorne School generally outperform School 21 on state assessments, with higher proficiency rates and better student subgroup performance. This suggests that the magnet school model may be more effective in improving student outcomes in the Yonkers district. Additionally, School 21 has a high percentage of students from low-socioeconomic backgrounds, which likely contributes to its overall academic underperformance.
