Port O Connor School
Summary:

The Calhoun County Independent School District (Isd) in Texas serves four elementary-level schools, ranging from a small rural campus of 64 students to a larger school of 836, all within a high-poverty area where free and reduced lunch rates hover between 65% and 74%.

The standout school is Port O Connor School, a tiny school of just 64 students that earns a 5-star rating and ranks in the 97th percentile statewide. It achieves 100% proficiency in 4th-grade Reading and 89% in Math, despite a 72% poverty rate, proving that small class sizes and high spending per student ($14,017) can overcome economic challenges. In contrast, Jackson/Roosevelt Elementary is the district's largest school (836 students) and a consistent 4-star performer, ranking in the 84th percentile and reliably exceeding state averages across all grades. Harrison/Jefferson/Madison Elementary earns a 3-star rating (59th percentile), while Seadrift School presents a paradox: its overall 2-star rating (42nd percentile) is dragged down by weak early elementary Math scores, yet its 8th graders achieve 78% proficiency in Reading and a perfect 100% pass rate on Algebra I exams, far exceeding district and state averages.

Key metrics show the district ranks 256th out of 951 in Texas (73rd percentile). Spending per student is inversely tied to school size, with Port O Connor spending the most ($14,017) and having the lowest student-teacher ratio (9.5:1), while Jackson/Roosevelt spends the least ($9,620) with the highest ratio (16.8:1). A district-wide weakness is 5th-grade Science, where scores range from 50% at Jackson/Roosevelt to a concerning 0% at Seadrift, despite the district outperforming the state average overall. For parents, Port O Connor offers exceptional results in a small setting, Jackson/Roosevelt provides reliable consistency, and Seadrift shows remarkable upper-grade strength despite early struggles.
