Not necessarily.. All you have to do is move to a different zone than the one you were in, you don't have to go to the school in your new address zone. You can choice to any school...BUT in this case I believe no move is required as he doesn't have a choice but to transfer.
2.4.4.1.9 Transfer Due to Change of Residence - The transfer is the result of a change in residence by the custodial parent(s), legal guardian(s) or Relative Caregiver to the attendance zone of a public school that student was not attending. If, as a result of the change of residence, the student could now enroll in a different public school, the student may make a one-time election and select any school including a private school. A change in residence has occurred when all occupancy of the previous residence has ended and a new legal residence has been established. Maintaining dual residency for purposes of athletic eligibility shall render the student ineligible.
Example: You can live in New Castle and move to Newark and choice to Smyrna per rule...
