People in Arlington either send their kids to public school or to school in DC (or Potomac or some in MD). The only mainstream private in Arlington is Catholic.
Again, if you want to send your kid to a private school, move to DC, Montgomery County or Arlington where they can easily commute. If you’re moving to Fairfax, Loudon or west, choose a neighborhood based on great publics, of which there are plenty.
