Summary:

The Calhoun County Independent School District (Isd) in Texas serves seven schools, including four elementary schools, one middle school, and two high schools, and is ranked in the 73rd percentile statewide with a 4-star rating.

Standout schools in the district reveal a clear "small school" advantage, though it is nuanced. Port O Connor School, with just 64 students, is the district's star performer, earning a 5-star rating and ranking in the 97th percentile, with 100% proficiency in 4th-grade Reading and 3rd-grade Reading. Seadrift School (202 students) is a "diamond in the rough," with low overall rankings but exceptional upper-grade results, including 100% proficiency in Algebra I. In contrast, Hope High School (21 students) spends the most per student ($30,440) yet has critically low academic performance, ranking in the 0th percentile, highlighting that small size alone does not guarantee success when serving high-needs populations. Jackson/Roosevelt Elementary is the most consistently high-performing traditional elementary school, ranking in the 84th percentile with strong scores across all subjects.

Key weaknesses include Travis Middle School, the district's lowest-performing school with a 2-star rating and alarmingly low math proficiency (only 21.95% in 8th-grade Math). Meanwhile, Calhoun High School performs solidly above average, especially in English II, with a 96.3% graduation rate. Spending does not correlate with performance, as Jackson/Roosevelt Elementary spends the least ($9,620 per student) but excels, while Hope High School spends the most with poor results. Overall, the district shows strong graduation rates (96.5% average) and low dropout rates, but parents should note the stark performance gaps between rural elementary schools and the struggling middle school.
