Summary:
Zip code 76455 is home to a single school, Gustine School, a small, rural PK-12 alternative campus within the Gustine Independent School District (Isd) that serves 136 students and is notable for its perfect graduation rate and exceptionally low student-teacher ratio.
Gustine School presents a compelling paradox for parents. On one hand, it excels in student support and retention: the student-teacher ratio is an impressive 7:1, the graduation rate is a perfect 100%, and the dropout rate is 0%. This suggests a highly personalized, nurturing environment where students are closely guided to completion. However, academic proficiency in core subjects for grades 3-8 is a significant concern, with scores in reading and math consistently falling 20-40 percentage points below state averages. For instance, 6th-grade math proficiency was 0% in the 2025-2026 school year. This indicates that while the school is effective at keeping students enrolled, it may struggle to deliver high-level academic instruction in the lower grades.
Interestingly, the school shows a stark contrast in upper-grade performance. In the same year, Gustine School exceeded state averages on the Algebra I (64.29%) and English I (61.54%) end-of-course exams, suggesting a stronger high school program or a particularly capable cohort of test-takers. The school also spends a high $16,866 per student, likely due to the fixed costs of running a full PK-12 district for a small population. A bright spot was 8th-grade science in 2024-2025, which scored 12 points above the state average. Parents should be aware that the small student body leads to extreme year-to-year volatility in test scores, making single-year data unreliable for long-term trends.
