Summary:
Zip code 78133 in Canyon Lake, TX, is home to two elementary schools, Mt Valley Elementary and Startzville Elementary, both serving grades PK through 5 within the highly-rated Comal Independent School District (Isd).
Mt Valley Elementary is the standout performer in the area, earning a 4-star rating and ranking in the top 20% of Texas elementary schools. It consistently outperforms Startzville Elementary in reading, math, and science, with 67.5% of students proficient in reading and 58.3% in math, compared to Startzville’s 56.5% and 45.7%, respectively. Startzville Elementary, a 3-star school, faces greater challenges, including a higher percentage of economically disadvantaged students (64.73% vs. 46.93%) and lower per-student spending ($10,237 vs. $12,050). Despite similar student-teacher ratios (around 13:1), the funding disparity likely contributes to the academic gap, with Startzville’s 5th graders particularly struggling—only 32% were proficient in science, well below the district average of 50.58%.
Both schools exceed the Texas state average in reading, but Startzville often falls short of the district’s high benchmarks. Mt Valley’s math performance is a key strength, though 3rd-grade math scores showed volatility, dropping from 69.49% proficiency in 2024-2025 to 48.31% the following year. For parents, Mt Valley Elementary offers a stronger academic track record and more resources, while Startzville Elementary, despite its challenges, remains part of a top-tier district and may benefit from targeted support in upper elementary grades.
