West Islip Union Free School District student-counselor ratio is 981:1 — well above typical (typically associated with unusually large scale or acute resource constraints)

student-counselor ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE counselors against total enrollment, districts that contract intervention or social-emotional staff outside the counselor classification may be under-counted Values this far above typical often signal acute resource constraints or a structurally different scale than most peers — worth reading alongside the underlying counts, not the ratio alone.

West Islip Union Free School District chronic absenteeism rate is 10.0% — low (typically associated with lower-than-average attendance disruption; districts in this range often have attendance interventions, robust transportation, or smaller catchments that reduce barriers)

chronic absenteeism rate is the simplest comparative metric but it does not capture the full picture: a student is chronically absent if they miss ≥10% of enrolled days for any reason, illness, family obligations, or disengagement Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
