St. Mary's County Public Schools student-counselor ratio is 380:1 — high (typically associated with staffing constraints that limit per-student counselor time; CRDC data shows higher ratios cluster in larger urban systems)

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 Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.

St. Mary's County Public Schools chronic absenteeism rate is 29.5% — near the typical range (US average ~28) — aligned with the national post-pandemic baseline of roughly 28% chronic absenteeism

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 Variation between sub-units within St. Mary's County Public Schools is typically wider than the St. Mary's County Public Schools-aggregate figure suggests.
