Summary:
In zip code 76941, there is a single elementary school, Irion Elementary, serving 200 students from Pre-Kindergarten through 6th grade in the rural community of Mertzon, Texas.
Irion Elementary is the sole elementary school within the highly-rated Irion County Independent School District (Isd), which ranks in the top 8% of all Texas districts. The school itself has consistently ranked in the top 30% of Texas elementary schools over the past three years, peaking in the 82nd percentile. A standout feature is its very low student-teacher ratio of 10.3:1, which, combined with high per-student spending of $12,783, suggests small class sizes and strong resource availability. Academically, the school's greatest strength is Reading, where students across all tested grades significantly outperform the state average (70% proficient vs. 54% statewide). Science performance is also a notable bright spot, with 5th graders scoring 40.7% proficient compared to the state average of 29.6%.
While the school excels in Reading and Science, its Math performance is more inconsistent, with some grades showing dramatic year-over-year swings. For instance, 3rd-grade Math jumped from 33.3% to 70% proficiency, while 5th-grade Math dropped from 59.3% to 40%. A common "4th grade slump" is also evident, with 4th-grade scores in both Reading (61.9%) and Math (42.9%) representing the lowest scores for the 2025-2026 school year. Despite its excellent resources and strong district reputation, the school's ranking has fluctuated between the 71st and 82nd percentile, indicating that while it is a very good school, it has not yet achieved elite status. Overall, Irion Elementary offers a high-quality, well-funded education with a clear emphasis on reading, though families should be aware of the variability in math performance across different grade levels.
