Summary:
The San Marcos Consolidated Independent School District is home to two middle schools—Miller Middle and Goodnight Middle—both serving grades 6 through 8 with similar enrollments of around 890 students each.
Miller Middle stands out as the higher-performing school in the district, consistently outperforming Goodnight Middle across nearly all academic metrics. In the 2025-2026 school year, Miller ranked in the 53rd percentile statewide (3 stars), while Goodnight ranked in the 22nd percentile (1 star). The most striking difference is in Algebra I proficiency: Miller achieved an exceptional 95.8% proficiency rate, far exceeding both the district average of 47.56% and the state average of 54.03%. Goodnight also performed well above the district average at 64.66% but remains significantly behind Miller. Despite having nearly identical resources—similar student-teacher ratios (14.6 vs. 15.3) and per-student spending ($10,097 vs. $9,838)—the academic outcomes are vastly different, suggesting that factors like school leadership, teaching quality, and curriculum play a critical role.
Both schools face challenges in mathematics, with proficiency rates well below state averages across all grade levels. For example, Miller's 6th-grade math proficiency was 25.74% and Goodnight's was 16.42%, compared to the state average of 38.57%. However, there is a bright spot in 8th-grade Social Studies, where both schools exceeded the state average of 31.69% (Miller at 38.25% and Goodnight at 30.53%). This suggests a potential area of strength in the district's social studies curriculum that could be replicated in other subjects. Overall, Miller Middle offers a stronger academic environment, particularly for advanced math students, while Goodnight Middle serves a higher-needs population and shows promise in specific subjects.
