Truancy laws already exist, and that's how they'd go about it. By making public education the only option, thereby mandatory, then hitting you with truancy violations. At that point, they don't need to define anything. Just a straight computer check of "if X child is old enough, are they enrolled and have they missed more than Y amount of days." Everything else wouldn't count and leave you in violation.
And I can speak from experience that cops love to go cowboy and turn a simple 30 day civil violation arrest into a dramatic raid and dragged out spectacle. Which would unfortunately break a lot of people into compliance.
