Summary

San Marcos High School is a large public high school in San Marcos, TX, serving 2,371 students in grades 9-12 and is part of the San Marcos Consolidated Independent School District, which ranks in the 32nd percentile statewide. The school has a history of low performance, currently sitting at the 36th percentile (2-star rating) for the 2025-2026 school year, though this marks an improvement from a low of the 21st percentile in 2022-2023. Over 73% of students qualify for free or reduced lunch, indicating a high level of economic disadvantage that is a key context for understanding the school's academic challenges.

When compared to nearby schools, San Marcos High School stands out for its persistently low academic achievement, particularly in Algebra I. In the 2025-2026 school year, only 11.74% of students scored proficient on the Algebra I End-of-Course exam, dramatically lower than the state average of 54.03% and far behind schools like Navarro High School (53.89%) and Lehman High School (37.24%). This "Algebra I crisis" has been a multi-year trend, with proficiency rates of 10.43%, 6.36%, and 7% in prior years. The school also has a higher dropout rate (2.5% in 2023-2024) compared to surrounding standard high schools, such as Canyon High School (0.7%) and Navarro High School (0.9%). However, there is a bright spot: U.S. History proficiency is relatively strong at 67.98%, close to the state average of 70.17% and competitive with Lehman (70.42%) and Canyon (71.33%).

An interesting finding is the stark contrast in performance between student subgroups. While White students at San Marcos High School rank in the 69th percentile statewide, Hispanic students rank in the 32nd percentile, and low socio-economic status students rank in the 29th percentile, indicating a significant achievement gap within the school. Nearby, Memorial Early College High School (a 5-star, 97th percentile school) demonstrates what is possible with a focused college-preparatory model, achieving near-perfect proficiency rates while serving a much more affluent student body (27% free/reduced lunch). The graduation rate at San Marcos High School has shown improvement, rising from 78.8% in 2020-2021 to 89.2% in 2023-2024, though a reported 39.2% rate for 2021-2022 appears to be a data error. Overall, the school faces significant challenges, but its recent upward trend in state ranking is a positive sign, though overcoming the deep-seated math deficit will require focused intervention.
