Summary:
Zip code 77982, serving the rural coastal community of Port O'Connor, Texas, is home to a single elementary school, Port O Connor School, which serves grades PK through 5 and is part of the Calhoun County Independent School District (Isd).
With only 64 students, Port O Connor School is a very small, tight-knit school that delivers exceptional academic results despite serving a high-poverty population where nearly 72% of students qualify for free or reduced lunch. The school's performance is remarkable, achieving a top 3% state ranking (97th percentile) in the most recent 2025-2026 data, earning a 5-star rating. Its standout feature is a powerful literacy program, with 4th graders achieving a perfect 100% proficiency rate in Reading and 3rd graders reaching 87.5% proficiency—both nearly double the state average. Math scores are also strong, with 4th graders at 88.89% proficiency, though 3rd grade math (62.5%) shows room for growth. The school's success is supported by a very low student-teacher ratio of 9.5:1 and high per-student spending of $14,017, which allows for intensive, individualized instruction that helps overcome socioeconomic challenges.
A key takeaway for parents is that this school's small size creates both opportunity and volatility. The dramatic ranking swings—from the 98th percentile down to the 78th and back up to the 97th—are typical for a school with only 64 students, where a single strong or weak class can shift overall performance significantly. However, the consistent pattern of outperforming state averages in core subjects, combined with the high investment per student, suggests that Port O Connor School is effectively leveraging its resources to provide a high-quality education in a supportive, rural environment.
