Summary:
The six public schools in zip code 78070 (Spring Branch, TX), all part of the highly-rated Comal Independent School District (Isd), serve students from elementary through high school and present a wide range of performance levels, from nationally competitive to solidly above average.
Bill Brown Elementary is the standout performer, ranking in the 98th percentile among Texas elementary schools with dramatically higher test scores than district and state averages, achieved with a very low free/reduced lunch rate. Smithson Valley Middle is a consistent high-achiever, ranking in the top 10% of Texas middle schools and posting phenomenal Algebra I pass rates near 100%. Smithson Valley High School is a rising star, improving to the 93rd percentile with a 97.6% graduation rate and test scores 20-30 points above state averages. In contrast, Rebecca Creek Elementary and Arlon R Seay Elementary have the lowest state rankings and highest free/reduced lunch rates, while Spring Branch Middle has the highest per-student spending but the lowest ranking among secondary schools.
Key takeaways include that higher spending does not guarantee higher performance, as the top-performing schools spend the least. A consistent "7th grade math slump" appears at both middle schools, where proficiency rates drop significantly compared to 6th and 8th grades. The high school functions as a well-oiled machine, combining top rankings with strong graduation and dropout rates, suggesting effective leadership and school culture across all metrics.
