Las Hermanas Mirabal Community School, Yonkers NY

Original Research by School Decision on Las Hermanas Mirabal Community School

Las Hermanas Mirabal Community School serves prekindergarten through 8th grade in Yonkers, a dense and revitalizing city in lower Westchester County where historic waterfront and downtown redevelopment have brought sustained investment and housing growth. The school is situated in an urban neighborhood and serves a highly economically disadvantaged population. A substantial share of students qualify for free or reduced-price lunch, and the student body is predominantly Latino, with a smaller share of Black students and Asian students.

State assessments for 2024-25 reveal a profile that requires close attention. In mathematics, proficiency varies sharply by grade. Fourth-graders achieved solid proficiency, while third, fifth, sixth, seventh, and eighth graders all fell well below that level, with particularly low results in third and sixth grade. English language arts results similarly range from quite low in sixth grade to more moderate performance in seventh and eighth grade, with third through fifth grades showing results below the middle range. Science proficiency in fifth grade was low; the school did not administer the eighth-grade science assessment, so no data is available for that grade. A standardized comparison across tested subjects and grades places the school in the bottom quartile among Westchester County districts. Parents may want to look into this further with the school, including what supports are in place for students, what the school sees as drivers of these results, and what interventions or curriculum changes are underway.

The school is a regular public school and is not charter or magnet. It is part of the Yonkers City School District, which is currently executing sustained modernization. The district opened its first new school in over two decades in September 2024, a dual-language community school, and has announced a second Pre-K-8 school for the Grant Park neighborhood. This growth reflects the district's effort to add capacity and update aging infrastructure as Yonkers itself sees substantial residential development. At the same time, the district closed Museum School 25 at the end of the 2024-25 school year due to low enrollment and high repair costs, so families in the district are navigating both openings and closures. Las Hermanas Mirabal itself is established and operational, and serves roughly a mid-sized student population for its grade band.

Yonkers itself is a mixed-income city in transition. Downtown has seen substantial private investment, including major residential towers, a revitalized waterfront esplanade, and the arrival of a major film studio complex expected to bring significant employment. The city is walkable, with strong transit access via Metro-North and extensive bus service, and anchors civic life around parks, libraries, and waterfront green spaces. Housing costs have risen with recent growth and revitalization, and rental costs have grown as well. The local employment base is broad, with health care, education, and retail forming the foundation alongside newer entertainment and media sectors.

The school district operates under mayoral control rather than an elected school board, a governance structure that affects parental voice and district decision-making and has drawn state scrutiny in recent years.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
