Class loads run heavy: 22.7:1 is larger than about 96% of Texas schools and 54% above the 14.7:1 state mean, so each teacher carries more students than is typical.
Its free-meal eligibility rate of 70.9% lands close to the Texas typical range, neither a high- nor low-need campus by this measure.
Enrollment of 704 puts it in the larger third of Texas schools by headcount.
Its Resource Investment Index trails 99% of the 8,960 Texas schools with a score on record, one of the lower results on this measure.
Among 1,811 similarly sized, similarly resourced-need Texas schools statewide, it ranks #1,792, in the lower tier once campus size and economic need are matched.
Its student body is predominantly Hispanic or Latino (91% of enrollment), among the less diverse in the state (diversity index 17/100).

Chronic absenteeism is elevated: 33.8% of students missed 10% or more of school days (2021-22 Civil Rights Data Collection).
