Summary:

The Irion County Independent School District (ISD) in Texas serves 334 students across two highly-rated schools: Irion Elementary (grades PK-6) and Irion High School (grades 7-12), both of which offer a small, resource-rich learning environment with very low student-teacher ratios.

Irion High School is a standout for academic excellence, boasting a perfect 100% graduation rate and a 0% dropout rate. Its state ranking has skyrocketed from the 69th percentile to the 92nd percentile (5 stars) in just two years, driven by exceptional End-of-Course exam scores—especially in English I Reading (91.3% proficient) and U.S. History (91.89% proficient), which far exceed state averages. In contrast, Irion Elementary excels at building a strong foundation, with 3rd-grade Reading proficiency at 90% and Math at 70%, both well above state norms. The elementary school has maintained a solid 4-star rating for three consecutive years, while the high school’s rapid improvement suggests highly effective recent changes in instruction or leadership.

A key finding is a notable dip in middle school math: 7th-grade Math proficiency at Irion High School is 44.44%, which, while above the state average of 29.41%, is a significant drop from the elementary school’s early math success. Both schools benefit from low student-teacher ratios (10.3:1 at the elementary and an exceptionally low 7.1:1 at the high school) and above-average per-student spending ($12,783 and $17,951 respectively), creating a supportive environment that yields strong results. The district ranks 71st out of 951 in Texas, earning a 5-star rating overall.
