Key Highlights
About Oak Heights
Oak Heights is an established residential neighborhood in San Marcos, Texas, located near the downtown square and Texas State University. Characterized by its mature tree canopy and a casual, "in-town" feel, the neighborhood developed primarily during the mid-to-late 20th century. Its streetscapes feature a mix of modest, single-family mid-century homes and small rental properties. The neighborhood's most prominent historical landmark is the Oak Heights Live Oak Tree, located in the 500 block of Franklin Drive. Recognized for its outstanding cultural, educational, and historical significance, the tree was officially designated as a local historic landmark by the San Marcos City Council under Ordinance 1986-81 in July 1986.

It is well-suited for individuals or small households who prioritize a central, established environment over the quietude of more rural or suburban outskirts.

Oak Heights Rankings
School Districts Serving Oak Heights
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.
