Schools and their ranking
Public Schools
The performance of Bay Area public schools varies widely. Almost all public schools have attendance zones, usually the immediate neighborhood, which means if you do not live in proximity to the public school, your children will not be able to attend. Typically one has no choice of school; your address determines the school.
Private Schools
There are over 700 private schools in the greater Bay Area, offering parochial, non-parochial and foreign-language education as well as boarding options.
Tuition ranges from an average of $5,000 a year for parochial schools (in-parish student) to an average of $10,000 a year for independent elementary schools and up to $16,000 a year for private high schools.
