Teachers union officials will also be closely monitoring the appeal. A.J. Duffy, president of United Teachers Los Angeles, said he agrees with the ruling.
"What's best for a child is to be taught by a credentialed teacher," he said.
While many educators and officials remained unfamiliar with the ruling Tuesday, news about it has been sweeping websites and blogs devoted to home schooling. Organizations have been getting tense phone calls from parents worried that they will be targeted.
Families who home school includethose whose religious beliefs conflict with public schools and those whose children are in the entertainment industry or have other time-consuming activities that require them to study at an individualized pace.
Glenn and Kathleen, a Sacramento-area couple who requested that their last name not be used for fear of prosecution, home school their 9-year-old son Hunter because their Christian beliefs would be contradicted in a public school setting, Glenn said. He is troubled by the idea that his son would be exposed to teachings about evolution, homosexuality, same-sex marriage and sex education .
"I want to have control over what goes in my son's head, not what's put in there by people who might be on the far left who have their own ideas about indoctrinating kids," he said.
If the ruling takes effect, Glenn vowed to move his family out of state. "If I can't home school my son in California, we're going to have to end up leaving California. That's how important it is to me."
