That concentration means South Texas Isd-wide averages can mask substantial variation outside the dominant entity. Grade band: high. A single dominant campus often anchors a district's program offerings and staffing patterns; the share helps explain why district-wide averages may not reflect the typical neighbourhood-school experience. When one entity dominates a region's footprint, its programmatic and budget decisions effectively set policy for a majority of the affected population.

South Texas Isd student-counselor ratio is 249:1 — low (typically associated with meeting or exceeding the American School Counselor Association (ASCA) recommended 250:1 benchmark, which correlates with stronger college and career counseling capacity)

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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.

South Texas Isd chronic absenteeism rate is 28.1% — 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 South Texas Isd is typically wider than the South Texas Isd-aggregate figure suggests.
