The New Hampshire State Supreme Court has agreed to hear the case of a 10-year-old Christian girl who was forced to attend public school.
A lower court had ruled that the girl could no longer be home-schooled by her mother.
The girl's parents are divorced.
The court cited the father's concerns about the child's strong religious beliefs, saying public school would expose her to other points of view.
"Courts can settle disputes, but they cannot legitimately order a child into a government-run school on the basis that her religious views need to be mixed with other views," the attorneys representing the girl's mother said. "That's precisely what the lower court admitted it is doing in this case."
The lower court also said the girl's mother has "more than kept up" with the public schools in teaching her daughter.
