Unhappy with the “world of mess” school her son was assigned to attend, Morna Atkins was thrilled when he won a spot in a magnet program at another campus. But the Orlando mother, who sent her son to private school for a time, too, doesn’t think parents unhappy with their local school should have to pay tuition bills or rely on the luck of a magnet program’s lottery draw to find something better. She’s delighted that starting in August a new state law will allow parents to transfer their children to any public school in Florida, if there is room.
