The reported share sits between 62.5% and 75%, above a simple majority but below the highest descriptive band used here. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.

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.
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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
This district scores well on funding equity, with balanced funding sources and good resource allocation.
