I found some stats on the Calif Dept of Education web site that may add to this discussion:

There are 9.674 public schools in Calif with an enrollment of approx 6.3 million students

There are 294,366 public school teachers
The average teacher-pupil ratio is 1 teacher to 21.4 students. (that's an average, obviously some classes are much larger, with the largest classes in grades 4, 5 and 6 at about 1 teacher to 35 students.)

Of those 9674 schools, 585 are charter schools enrolling about 223,000 students.

There are 3506 private schools in Calif enrolling 584,983 students. The majority of children in private schools are in grades K-8, only 159,736 students are enrolled in private high schools. Among the private schools, about 1/3 are very small with just 6-36 total students.

My local newspaper reported earlier in the week that they don't keep records on just how many students in Ca are home schooled, but it's estimated at about 200,000 statewide.
