What stands out at Mamaroneck Avenue School

Scale and staffing sit near the state mainstream

Mamaroneck Avenue School is neither an extreme outlier in enrollment nor in student-teacher ratio among New York schools. Its profile therefore turns on the other dimensions rather than on scale alone: economic need, counselor coverage, program access, attendance, and district finance. This middle placement is useful because it prevents the campus from being mislabeled as unusually large, small, crowded, or teacher-dense when the federal comparison does not support that claim.

Need and resources require a component-level read

Mamaroneck Avenue School falls within the wide middle of the New York distribution on both free-meal eligibility and the Resource Investment Index. Neither measure supplies an honest headline by itself. The useful distinctions are in the components: classroom staffing, counselor availability, attendance, gifted-program access, and district spending. Those fields can pull in opposite directions even when the overall percentile looks ordinary.

Attendance is the dominant support signal

Mamaroneck Avenue School's 25.7% chronic-absence rate is more consequential than a generic staffing label: at least one quarter of students missed 10% or more of school days in the 2021-22 collection. That level can affect instruction, counseling demand, and continuity even when other reported resources look ordinary. The dataset records the scale of absence but not its causes, so it should prompt a current-year question rather than a conclusion about school management.

Mamaroneck Avenue School is a mid-sized elementary school in Mamaroneck, New York, enrolling 611 students.

Class sizes run a bit leaner than typical: 9.3:1 puts it in the smaller third of New York schools by student-teacher ratio.

Its free-meal eligibility rate of 46.8% lands close to the New York typical range, neither a high- nor low-need campus by this measure.

Enrollment of 611 puts it in the larger third of New York schools by headcount.

Its Resource Investment Index lands in the upper third of 4,801 scored New York schools.

Against 721 statewide peers matched on enrollment and economic need, it ranks in the upper tier at #178.

Its student body is led by Hispanic or Latino (53%) and White (34%) (diversity index 60/100).

Chronic absenteeism is elevated: 25.7% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).

Mamaroneck Union Free School District also operates Mamaroneck High School (1,764 students) and Hommocks School (1,284 students) alongside Mamaroneck Avenue School.
