Below, I've included a link to a list of all preschools in San Mateo, CA using our SchoolFinder feature. Each individual school page contains an overview, enrollment information, and contact info. Many of the schools also feature community reviews.
If you are considering teaching your child yourself or with friends take a look at www.myhomepreschool.net. This program provides you with complete lesson plans. Each day is about 2 hours long. I use this with my two kids and they love it!
