Post High School

Post High School is a small, rural high school in Post, Texas, serving 233 students in grades 9-12 within the Post Independent School District (Isd), where over 65% of students come from low socio-economic backgrounds.

Post High School presents a notable paradox: it boasts an exceptional graduation rate of 97.6% and a near-zero dropout rate, suggesting a supportive environment that keeps students on track to earn diplomas. However, its academic proficiency on state assessments has declined sharply over the past four years, dropping from the 78th percentile statewide to the 19th percentile. For example, Algebra I proficiency fell from 57% in 2022-2023 to just 5.36% in 2024-2025, though it rebounded to 22% in 2025-2026—still far below the state average of 54%. This pattern indicates the school excels at retention but may struggle to ensure students master grade-level content. Compared to the nearby Garza County Rjc, an alternative campus with only 23 students, Post High School significantly outperforms in academic metrics, such as Biology proficiency (57.14% vs. 21.43%) and English I Reading (43.14% vs. 11.11%), while maintaining a favorable student-teacher ratio of 10.3:1.

The school’s decline appears systemic, affecting most student subgroups, but support for vulnerable populations has been especially volatile. English Language Learner (ELL) students ranked in the 85th percentile in 2021-2022 but fell to the 2nd percentile in 2023-2024, while At-Risk students dropped from the 89th percentile in 2020-2021 to the 51st percentile two years later. This inconsistency suggests that programs for these groups may depend heavily on specific staff or resources that have changed. For parents, Post High School offers a tight-knit, personalized learning environment with strong graduation outcomes, but the recent academic slide and erratic test scores warrant close attention to how the school addresses core instruction and supports its most vulnerable learners.
