What this school's NCES data tells you
Clark H S reports 1,114 enrolled students to the National Center for Education Statistics (NCES) alongside 81.0 full-time-equivalent teachers, producing a 15.8:1 student-teacher ratio. That figure sits 8% above the Texas state mean of 14.6:1, signalling larger average class loads than peers in the same state. Against the national 2024-25 average of 15.9:1, it is 1% lower, a useful calibration for families comparing districts across state lines.
Title I and federal lunch eligibility offer another window into the student body: 34.2% of pupils qualify for free meals, a proxy for household income that federal programs use to direct funding. The free-lunch share is 45% below the Texas average and 34% below the national baseline. The school offers 5 Advanced Placement courses, a stronger academic pipeline indicator than enrollment alone. Counselor coverage works out to roughly 279 students per counselor, above the ASCA-recommended ceiling of 250:1. Chronic absenteeism — missing 10% or more of school days — stands at 28.6% according to the 2021-22 Civil Rights Data Collection.
