What stands out at Clay Hill Public Charter School
Clay Hill Public Charter School is a higher-need, mid-sized charter elementary school in Baltimore, Maryland, enrolling 335 students.
Class loads run heavy: 19.7:1 is larger than about 96% of Maryland schools and 36% above the 14.5:1 state mean, so each teacher carries more students than is typical.
Its free-meal eligibility rate of 56.6% lands close to the Maryland typical range, neither a high- nor low-need campus by this measure.
Enrollment of 335 puts it in the smaller third of Maryland schools by headcount.
Its Resource Investment Index lands in the lower third of 1,382 scored Maryland schools.
Among 193 similarly sized, similarly resourced-need Maryland schools statewide, it ranks #153, in the lower tier once campus size and economic need are matched.
Its student body is led by Hispanic or Latino (75%) and African American (17%) (diversity index 40/100).
Counselor access is stretched at roughly 419 students per counselor, well above the ASCA-recommended 250:1 ceiling.
Chronic absenteeism is elevated: 26.0% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 15.3% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
Among Baltimore's elementary schools, it stands alongside Kipp Harmony Academy (1,399 students): Clay Hill Public Charter School is smaller than that campus by headcount and runs heavier classes (19.7:1 vs 13.7:1).
