Summary:
The two public schools in zip code 76941, serving the rural community of Mertzon, Texas, are part of the highly-ranked Irion County Independent School District (Isd), which serves 334 students from Pre-K through 12th grade and ranks in the 93rd percentile of Texas districts.
Irion High School is the standout school in this area, ranking in the top 8% of Texas high schools (92nd percentile) for the 2025-2026 school year. It boasts exceptional academic performance, with proficiency rates on End-of-Course exams in English I Reading (91.3%), English II Reading (88.46%), and U.S. History (91.89%) far exceeding state averages. The high school also achieves a perfect 100% graduation rate and a 0% dropout rate, supported by an exceptionally low student-teacher ratio of 7.1:1 and high per-student spending of $17,951. In comparison, Irion Elementary is a solid, above-average school ranking in the 75th percentile (4 stars), with a standout 3rd-grade reading proficiency rate of 90%—nearly 40 points above the state average. The elementary school also benefits from small class sizes with a 10.3:1 student-teacher ratio.
A key takeaway is the effective educational pipeline from elementary to high school, though a persistent "math gap" exists. At the elementary level, 4th and 5th-grade math proficiency (42.86% and 40%) falls below state averages, while at the high school, 7th-grade math (44.44%) is the only subject not dramatically outperforming the state. The high school has shown significant year-over-year improvement, jumping from the 69th to the 92nd percentile, and the district's low economic disadvantage rates (around 27-30%) and high resource investment create an environment for personalized instruction that drives these strong outcomes.
