The free-lunch share is 47% above the Texas average and 75% above the national baseline. The school offers 1 Advanced Placement course, a stronger academic pipeline indicator than enrollment alone. Chronic absenteeism — missing 10% or more of school days — stands at 100.0% according to the 2021-22 Civil Rights Data Collection.
