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

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.
