Let’s take an easy, kid-friendly tour across California to see what makes these schools shine and how they help students do their very best every day!
What Makes a Private School Special?
A private school is different from a regular neighborhood school. Instead of receiving tax dollars from local cities, private schools are run independently and funded directly by tuition and community donations.
Because they make their own plans, private campuses offer special benefits:
Smaller Class Sizes: Instead of 30 kids in a room, you might only have 12 to 15 classmates. That means teachers have plenty of time to answer every question.
Hands-on Learning: Many private schools have maker labs, giant telescopes, black-box theaters, and coding studios.
Unique Ways to Learn: Some focus on foreign languages, some follow Montessori or Waldorf styles where you learn by creating things, and others focus heavily on college preparation.
Caring Communities: Teachers, students, and parents often get to know each other really well, creating a warm, supportive team.

| Class Size | Usually very small (often 10–18 students) | Usually medium to large (20–30+ students) |
| Curriculum | Can design unique programs, arts, and STEM | Follows statewide educational standards |
| Admission | Requires an application, test, or interview | Automatic enrollment based on where you live |
