As we enter the spring home-buying season, relocating parents look for the school districts that will give their children the best education possible. Choosing a top district promotes a bright future as well as a stable childhood. To find the K-12 school districts that provide consistently top-tier education, NerdWallet considered:

  • Do the schools meet standards for excellence? We defined an excellent school as one with an academic performance index (API) above 900.
  • Quality education at every level: Can a child attend excellent schools from kindergarten through high school?
  • Accessible education for all: Does the district promote educational quality for all students in the district?

In sunny Orange County, Laguna Beach High School boasts class sizes under 30; a near-perfect graduation rate; and teacher salaries topping 36% of the state average. LBUSD invests in its students, teachers and staff; that investment clearly pays off.

5. Oak Park Unified School District

Top Schools API
Oak Hill Elementary 960
Medea Creek Middle 934
Oark Park High 924

Ventura County’s Oak Park Unified School District boasts its fair share of accolades: In the past year, it’s won the Golden Bell Award for its Chinese program; the Green Schools award, for the most eco-friendly district in California; and the Five-Star GATE Award for its nurturing of gifted students.

6. Palos Verdes Peninsula Unified School District

Top Schools API
Cornerstone Elementary 974
Ridgecrest Intermediate 958
Palos Verdes Peninsula High 906

Palos Verdes is no stranger to the spotlight: the Washington Post, Newsweek and others listed Palos Verdes Peninsula High School among the best in California and in the nation. Just last week, student Alexander Chen was named the California State Science Fair Student of the Year. The high school’s students speak 47 languages, and 98% go on to postsecondary education. But the PVPUSD commitment to education starts well before then: its top-ranked elementary school, Cornerstone, focuses on a holistic, well-rounded education. By involving parents and community members early on, Cornerstone prepares its young students for the rapidly changing world.

Turtle Rock Elementary boasts a score of 980, putting it squarely in the top 1% of state elementary schools. Northwood High School was among just 218 middle and high schools honored as a California Distinguished School in 2013.

A full 94% of AP test-takers scored a passing grade of 3 or higher, and nearly three in four high school students take at least one rigorous AP course. Students enter into top-tier elementary schools – Herbert Hoover Elementary has the fifth-highest API in California – and graduate with the skills necessary to succeed in college and beyond. The mean SAT score of 1945 simply blows the state average out of the water.

10. Pleasanton Unified School District

Top Schools API
Mohr Elementary 964
Harvest Park Middle 943
Amador Valley High 900

Though an academic powerhouse, Pleasanton is known for far more than test scores. Amador Valley High Schools’ wind ensemble was chosen to perform in the 2013 Midwest Clinic, among the highest honors for a high school music program. Harvest Park Middle School showed significant growth in academic performance, improving its API by 18 points in 2012 and showing robust growth in minority groups. And the opportunities extend beyond the classroom as well: Lawrence Livermore Labs recently granted $100,000 to Amador Valley High and Fairlands Elementary to foster science in the classroom.

Methodology:

Data came from the California Department of Education

  • Each district must have at least one elementary, middle and high school with a 2012 growth API over 900 to be considered
  • We then considered the probability that a student would attend a school with an API over 900 at each level
  • Average API was used as a tiebreaker
