San Marcos Consolidated Independent School District
Grades K–125/10
11 schools Rating range: 48 / 10

San Marcos Consolidated ISD is a district in transition, currently balancing modest academic gains (improving to a TEA 'C' rating) against severe financial and operational headwinds. While the portfolio features several high-performing elementary schools and a commitment to growth through 'Turnaround' plans and instructional interventions, the district is hampered by a projected $7 million budget deficit and below-average state proficiency scores in core subjects. Significant red flags include a federal hazing lawsuit, community dissatisfaction regarding safety protocols, and a lack of local interest in school board service, which suggests a strain on community trust. The district remains a diverse and supportive environment with strong 'Rattler' pride, but its financial instability and the sharp performance gap between elementary and secondary tiers place it firmly in the 'Mixed' category.
