In Mississippi, lawmakers have rejected a plan that would have allowed home-schooled students to participate in extracurricular activities in the school districts where they live. Legislators said that they feared good athletes with bad grades who were dismissed from a team might leave public school to become home-schooled, and then play sports.
A similar law in Florida allowed former college quarterback Tim Tebow to play ball while he was home-schooled, so Mississippi had called it, "the Tim Tebow Rule".
Ohio has a better system. It has allowed home-school students to participate in school activities since 2013, but the students are required to keep their grades at the same standards as students who do attend the public schools.
