During a break in a high school debate tournament not long ago, my 17-year-old son struck up a conversation with a student on the rival team from a New Jersey public school. "Where’s your school?" asked the boy. When my son replied that he was home-schooled, the student probed.

"How do you socialize when you’re at home all the time?" he asked.

"Well, for one thing, I’m here, right?" my son laughed.

My children have gotten used to most of the standard questions from their conventionally schooled peers: Are you super-religious? Do you stay at home in your pajamas and watch TV all day? Is your mom a teacher?

Adults, on the other hand, can be surprising. Like the professor at the community college where one of our sons was taking a course, who went out of her way to pull him aside, sit him down and tell him, "You home-schoolers think you can change the world. But you can’t. Nobody can."

It’s hard to generalize about home-schoolers, but if there’s one thing we know, it’s that we are changing the world, or at least the world of education choices. Others, though, see us as either misguided or threatening — and probably cheered last month’s California appeals court ruling that all children in the state must be taught by credentialed teachers. At least 166,000 California children are home-schooled. And most home-schooling parents don’t have teaching credentials, so the ruling is worrisome, even though Gov. Arnold Schwarzenegger called it "outrageous." The decision will probably be appealed, but the teachers’ unions are applauding in the meantime.
