I have two kids at Picasso, a Tigger (the 3 year old class) and a Kinderoo (the 5 year old kindergarten class). The staff is fantastic across the board, which is of course the most important thing. We just had some friends transfer their child to Picasso from one of the other local highly acclaimed preschools and they are blown away by how great the teachers and kids are at Picasso. All the kids get along, there is no fighting, the kids are polite, etc. I have literally spent hundred of hours there over the last few years and am amazed at the kids at Picasso. This is not a coincidence - the kids are great because the direction, care, and instruction they are receiving is top notch.
On a superficial note, I agree with the other reviewer that the facility itself could use some cosmetic upgrades, but the location is hard to beat - the children get to play outside with a view up and down the entire San Mateo coast. I would suggest that if you want to check out Picasso you bring your child there for a few hour trial run and see how they do. Having spent plenty of time on the playground watching kids play I can confirm that the teachers are not helicopter teachers out there because they don't have to be - the kids are well behaved and fantastic - now if I could just get my kids to be as well behaved at home : ).
As a side note, Picasso is a feeder school for many of the top private schools in the area should you want to continue in private school for primary school. I know that both Seacrest on the coast, and Notre Dame in Belmont find Picasso kids to be well prepared. read more
