Summary:
Zip code 76233, serving the Collinsville, TX area, is home to two public schools within the Collinsville Independent School District (Isd), a small district ranked in the 65th percentile statewide with a 3-star rating and approximately 600 students.
The standout school in this area is Collinsville High School, which serves grades 6-12 and demonstrates clear strengths. It has shown a strong upward trend in state ranking, climbing from the 50th to the 69th percentile over three years. The high school excels in End-of-Course exams, significantly outperforming state averages in Biology (80.56% vs. 70.51%), English I Reading (73.68% vs. 55.43%), and English II Reading (75.47% vs. 59.88%). It also boasts a high graduation rate of 96.8% and a low dropout rate of 0.4%, with a favorable student-teacher ratio of 11.1:1 and higher per-student spending of $13,499. In contrast, Collinsville Elementary (PK-5) shows more mixed results, with a slower rate of improvement and a notable weakness in 5th-grade reading proficiency (44.44% vs. state 58.47%), though it excels in 5th-grade math (61.11% vs. state 47.38%).
A key finding is the "Collinsville Paradox," where the high school is a clear outperformer while the elementary school is more average, suggesting resources may be concentrated at the secondary level. Science is a strength at the high school but a weakness at the elementary level, with 5th-grade science proficiency at just 21.15% (state: 29.57%). The most critical challenge is a "middle school math dip," with 6th-grade math proficiency alarmingly low at 19.35% (state: 38.57%), indicating a gap in foundational math skills that appears to be addressed by the time students reach Algebra I. Overall, families can expect a high-performing high school with strong literacy and science programs, but should be aware of inconsistent elementary results and a significant math challenge in the middle grades.
