Carillon Preschool

What these mean, and where they come from

Small means the smallest quarter of Bay Area’s 439 licensed centers by state-licensed capacity: 8 to 30 children. Medium is 31 to 75; large is 76 to 312.

How they teach

Developmental and academic

“Carillon School offers a faith-based developmental program for children aged 24 months to 5 years as of September 1st.”In their words, July 2026.carillonschool.org

“Our pedagogy is a blend of play and academics.”In their words, July 2026.carillonschool.org

One of 30 Bay Area providers that describe a developmental approach, out of 164 that describe any approach at all.

Who cares for your child

One adult for every seven children

Shortlist has not yet sourced this state’s legal ratio limit, so there is nothing to set this beside yet.

Cara O'Connell (Director) since 2015.

Of 905 Bay Area providers, 29 publish how long a named staff member has been there; the longest tenure at each of those has a median of sixteen years.

What it costs

$1,536 a month for a preschooler

Bay Area comparison hidden: this is a half-day price, and only full-time prices are compared.

Half-day (morning) $236 to $978 a month. Application fee $100. Sibling discount: offers a discount for siblings enrolled. Prices from their website, July 2026.

Shortlist doesn’t have these yet: a typical day, sick and biting policies.
