Why Mountain House Schools Are Among the Best in California
If you're considering a move to Mountain House, the schools might be the single biggest reason to make the leap. The Lammersville Joint Unified School District (LJUSD) — serving approximately 7,949 students across 9 campuses — ranks in the top 5% of all California school districts for academic performance. And the numbers aren't even close.
70% math proficiency. The California state average is 34%. 73% reading proficiency. The state average is 47%. These aren't cherry-picked statistics — they're district-wide CAASPP results that reflect the performance of every student, at every school, across every grade level.
Mountain House High School: National Blue Ribbon 2024
The crown jewel is Mountain House High School, home of the Mustangs. In 2024, MHHS was named a National Blue Ribbon School by the U.S. Department of Education — an honor awarded to less than 1% of public schools in the entire country. With a 9/10 GreatSchools rating, an A grade from Niche, 29 varsity sports programs, and six CTE career pathways (including Biomedical Sciences, Computer Science, and Engineering), MHHS offers the kind of comprehensive education that rivals many private schools.
The Early College Pathway Program with San Joaquin Delta College allows motivated students to earn an Associate degree alongside their high school diploma — tuition-free.
Elementary Excellence: Cordes Leads the Way
At the K-8 level, Julius Cordes Elementary (Cheetahs) is the standout, ranking in the top 2% of California elementary schools with 84% math and 85% reading proficiency. That's more than double the state average.
But Cordes isn't an outlier — it's part of a pattern. Altamont Elementary posts 68% math and 76% reading. Evelyn Costa Elementary, which only opened in 2023, already ranks in the top 6.3% statewide. Bethany, Questa, Hansen — each carries an 8/10 GreatSchools rating. Even Wicklund Elementary, the original school that opened with the community in 2005, maintains a solid 7/10.
What Makes LJUSD Different?
Three things set Lammersville apart:
1. Project Lead The Way (PLTW) — Every school in the district offers PLTW STEM curriculum, giving students hands-on experience in engineering, computer science, and biomedical sciences starting in elementary school.
2. Village-Centered Design — Each Mountain House neighborhood is built around its K-8 school, creating walkable, community-centered campuses where families know their teachers and neighbors.
3. Investment in Growth — The 10th school, Pombo Elementary, breaks ground in 2025 to serve The Lakes development, with capacity for 950 students on a 16-acre campus.
The Bottom Line
Mountain House families don't have to choose between affordable housing and great schools. They get both. For families relocating from the Bay Area — where comparable school quality often comes with a $2M+ price tag — Mountain House offers something remarkable: top-5% academics at a fraction of the cost.
