Class loads run heavy: 21.3:1 is larger than about 95% of Texas schools and 45% above the 14.7:1 state mean, so each teacher carries more students than is typical.
Its free-meal eligibility rate of 66.6% lands close to the Texas typical range, neither a high- nor low-need campus by this measure.
Enrollment of 680 puts it in the larger third of Texas schools by headcount.
Its Resource Investment Index trails 97% of the 8,960 Texas schools with a score on record, one of the lower results on this measure.
Among 1,708 similarly sized, similarly resourced-need Texas schools statewide, it ranks #1,643, in the lower tier once campus size and economic need are matched.

Chronic absenteeism is elevated: 30.1% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
Its district draws 20.4% of revenue from federal sources, an above-typical federal share that tends to track a higher-need student population.
