Summary:
Zip code 77982 is home to a single school, Port O Connor School, a small, rural elementary school serving grades PK through 5 with a total enrollment of just 64 students. This school is part of the Calhoun County Independent School District (Isd), which is ranked in the 73rd percentile among Texas districts. The school serves a high-needs population, with 71.88% of students qualifying for free or reduced lunch, and benefits from a very low student-to-teacher ratio of 9.5:1 and a per-student spending of $14,017.
Port O Connor School demonstrates exceptional academic performance, particularly in Reading, where it has achieved near-perfect or perfect proficiency rates. In the most recent data, 4th graders achieved a 100% proficiency rate in Reading, and 3rd graders achieved 87.5%, both significantly higher than district and state averages. Math performance is also strong, with 4th graders at 88.89% proficiency, though 3rd-grade Math at 62.5% shows a notable drop from the previous year. The school's state ranking history is volatile but shows elite-level performance, ranking 121st out of 4,627 (97th percentile) in 2025-2026, after dropping to 1,036th in 2023-2024 and then rebounding from 92nd in 2022-2023.
The most compelling finding is that Port O Connor School achieves top-tier academic results while serving a student population where nearly 72% are economically disadvantaged, indicating a highly effective school overcoming significant socioeconomic barriers. The school's heavy investment in resources, with spending well above the state average and a very low student-teacher ratio, appears to be paying off. However, the volatility in state ranking is likely due to the very small sample size of 64 students, where a single year's cohort can significantly skew overall results. Reading is a clear strength, suggesting a highly effective literacy program, while Math performance, though strong overall, shows a potential challenge in the 3rd-grade curriculum that may warrant attention.
