If the home instruction meets the necessary academic standards, and legitimate cause exists for remaining out of public school, then I would agree. I wouldn't support public funding of home schooling.
Should child home schooling be supported as a viable option by the government?
For reasons other than religious, yes.
Coming from a military lifestyle, I have to say yes. I know several families that home schooled their kids. That way they knew everything was not only covered, but consistant. While it is not for everyone, there are definitley circusatnces where it is the best option.
