Summary:
The Columbia-Brazoria Independent School District (Isd) is served by a single high school, Columbia High School, which enrolls 885 students in grades 9 through 12 and is located in a rural area of Texas.
Columbia High School presents a mixed picture for parents. On the positive side, the school boasts a very high graduation rate of 96.4% and a low dropout rate of 0.5%, indicating it is effective at keeping students on track to earn a diploma. However, the school's state ranking has been in a steady decline, dropping from the 48th percentile (2 stars) in 2023-2024 to the 29th percentile (1 star) in 2025-2026. The most critical concern is in Algebra I, where only 5.99% of students were proficient in the most recent testing year, compared to the state average of 54.03%. Performance in other subjects is mixed: the school nearly matches the state average in English II Reading (59.18% vs. 59.88%) and is close in Biology (64.84% vs. 70.51%), but it falls significantly behind in U.S. History (55.97% vs. 70.17%) and English I Reading (40.63% vs. 55.43%).
This creates a notable paradox: the school excels at graduating students but struggles to achieve academic proficiency in core subjects, particularly math. With a student-teacher ratio of 15.5:1 and per-student spending of $10,336, the school's resources appear adequate, which raises questions about why academic outcomes, especially in Algebra I and U.S. History, are not stronger. The data strongly suggests that targeted interventions in mathematics instruction and curriculum are urgently needed to reverse the school's downward trend and better prepare students for state standards.
