In other parts of the California code, a “private school” is defined as a “person, firm, association, partnership, or
corporation offering or conducting private school instruction on the elementary or high school
level.
As I've read elsewhere, that's a pretty broad definition, and there's nothing in that definition of “private school” that would exclude someone teaching his children at home.
A parent teaching her children at home would be a "person... offering or conducting private school instruction..."
Thus, meaning is given because meaning is provided by the code itself.

I've said it before and I'll say it again. You can make poorly written code say anything that you want it to say. And California homeschooling code is a good example of poorly written code, in my opinion.
