Laura McIntyre began educating her nine children more than a decade ago inside a vacant office at an El Paso motorcycle dealership she ran with her husband and other relatives.

Now the family is embroiled in a legal battle the Texas Supreme Court hears next week that could have broad implications on the nation's booming home-school ranks. The McIntyres are accused of failing to teach their children educational basics because they were waiting to be transported to heaven with the second coming of Jesus Christ.

At issue: Where do religious liberty and parental rights to educate one's own children stop and obligations to ensure home-schooled students ever actually learn something begin?

"Parents should be allowed to decide how to educate their children, not whether to educate their children," said Rachel Coleman, executive director of the Massachusetts-based Coalition for Responsible Home Education.

Like other Texas home-school families, Laura and her husband Michael McIntyre weren't required to register with state or local educational officials. They also didn't have to teach state-approved curriculums or give standardized tests.

But problems began when the dealership's co-owner and Michael's twin brother, Tracy, reported never seeing the children reading, working on math, using computers or doing much of anything educational except singing and playing instruments. He said he heard one of them say learning was unnecessary since "they were going to be raptured."
