So, you are looking for information about San Fran school systems? The public or private systems? Usually the public school choice in the US is determined by the location of your house. Any realtor can tell you which school districts are good, not so sure if they can tell you which ones are bad. But the bad ones are the ones that aren't mentioned on the good list. Also, the district is usually defined by the quality of its high school (ages 14-18). Used to be that CA had a great reputation for schools, but now the state is a fiscal mess and who knows if they will even have public schools next year (okay, I am stretching the truth).
