Summary:
The city of Mertzon, Texas, is served by two public schools within the Irion County Independent School District (Isd), a small, rural district with about 334 students across grades PK-12. Irion Elementary (PK-6) and Irion High School (7-12) both perform well, but the high school stands out as the district's academic powerhouse. The district itself ranks in the top 8% of Texas districts, earning a 5-star rating, driven largely by the high school's exceptional recent performance.
Irion High School has achieved a remarkable turnaround, jumping from a 3-star rating (69th percentile) in 2023-2024 to a 5-star rating (92nd percentile) in 2025-2026. It boasts a perfect 100% graduation rate and 0% dropout rate, with English I and II proficiency rates (91.3% and 88.46%) far exceeding state averages. The high school also benefits from an exceptionally low student-teacher ratio of 7.1:1 and high per-pupil spending ($17,951), creating an environment for intensive, personalized instruction. In contrast, Irion Elementary is a consistent, high-performing feeder school with a 4-star rating for three consecutive years. While its reading scores are strong—especially 3rd grade at 90% proficiency—the elementary school shows a notable weakness in math, with 4th and 5th-grade proficiency rates (42.86% and 40%) falling below state averages.
The key takeaway for parents is that the district offers a strong, supportive educational path, but with a clear split in strengths. The high school excels in English and history, while the elementary school provides a solid foundation in reading but struggles with math, which could affect students transitioning to high school courses like Algebra I. The district's low percentage of economically disadvantaged students (around 27-30%) and small class sizes (10.3:1 at the elementary, 7.1:1 at the high school) are significant advantages. Overall, Irion High School is the standout, but families should be aware of the elementary math gap when planning for their child's long-term academic success.
