Summary:
Zip code 75481 is home to a single school, Sulphur Bluff Independent School District (ISD), a small, rural public school serving 209 students from Pre-Kindergarten through 12th grade in a tight-knit community.
Sulphur Bluff ISD stands out for its exceptional high school outcomes, boasting a perfect 100% graduation rate and a 0% dropout rate. The school excels in high school humanities, consistently outperforming the state average in English I and II Reading and U.S. History on End-of-Course exams. With a low 10:1 student-teacher ratio, students receive significant individualized attention. However, the school shows a stark contrast between elementary and high school performance. In the 2025-2026 school year, 5th and 6th grade reading scores were significantly below state averages (25% and 27.27%, respectively), while 7th grade reading and math scores jumped to 70% and 60%, well above state averages. This "7th grade bump" suggests a potential shift in instructional effectiveness or student maturation. A persistent weakness is Algebra I, where the school scored just 27.27% in 2025-2026, far below the state average of 54.03%.
Despite spending $12,546 per student—higher than the Texas average—and maintaining small class sizes, the mixed academic results indicate that resources alone don't guarantee success. The school's ability to eventually bring students to proficiency in high school is a testament to its dedicated staff, but the data clearly points to a need for targeted intervention in elementary reading and math, as well as Algebra I. For parents, this school offers a supportive environment with strong high school academics, but they should be aware of the challenges in the lower grades and the need for supplemental support in key areas.
