Here’s a Y! map of all San Francisco K-8 schools. I put this together several months ago but I decided not to release it until my kid got into kindergarten. (We are just that competitive with our four-year-old.)
We found this map to be very helpful last year when we were trying to figure out where to apply for Celeste. We obviously wanted her to get in somewhere "good" but we also didn’t want to have to drop her off in north beach every morning before turning around and commuting down the peninsula. We’re very excited that we got our first choice, which is the Spanish immersion program at Fairmount Elementary, about five minutes drive from our house. Muy bueno!
