I live and work in Ross, and my children attend Ross School. Much of the advice you have received is correct. However, Steve of Fremont mistakenly sent you the incorrect school district for Ross. We are Ross School District, NOT Ross Valley School District. Ross School District is for Ross residents and residents of certain parts of Kentfield. It does not have an enrollment crisis. In fact, we just built a beautiful new school. It is a single school district, K-8 on one campus, and a California distinguished school. Ross Valley School District covers San Anselmo and Fairfax and some smaller communities in West Marin.
In Mill Valley, you are not guaranteed your nearest school, but it is a factor used in determining placement. And my friends and clients who have children in Mill Valley schools tell me that most children eventually are able to transfer to their nearest school even if it is initially full.
I recommend the website http://www.greatschools.net
-- very useful school information. On my website, http://www.stephanielamarre.com,
I have links to that site and many others to guide you in your school search.
As a specialist in Ross and Mill Valley, I would be happy to answer any questions you have or assist you in your home search. Kind regards,
