Frequently Asked Questions

How many licensed preschools are in Ontario?

Ontario has 28 licensed childcare programs that serve preschool-age children (ages 2–5). This includes dedicated preschool centers and family child care homes whose licenses cover this age group.

What's the difference between a preschool and a daycare center?

In California licensing terminology the two overlap significantly — most "preschools" are licensed as Child Care Centers that happen to serve children ages 2–5 with a structured curriculum. Dedicated preschool programs tend to emphasize school readiness, early literacy, and social-emotional development.

How much does preschool cost in Ontario?

Typical monthly tuition for a preschool program in San Bernardino County is about $742 at a center and $858 at a family child care home (based on 2022 benchmark data). Part-day and half-day programs cost less.

What should I look for when choosing a preschool?

Look for a published curriculum or teaching philosophy, low teacher turnover, outdoor play space, a clean inspection history on the facility's page, and caregivers who engage warmly with children during your tour. Ask about ratio (state maximum is 1:12 for preschoolers), transition plans to kindergarten, and how behavior and conflict are handled.
