Va. Code § 24.2-604.6
Minors may be permitted to enter a polling place on the day of the election to vote in a simulated election at that polling place, provided that the local electoral board or general registrar has determined that such polling place can accommodate simulated election activities without interference or substantial delay in the orderly conduct of the official voting process. Persons supervising or working in a simulated election in which minors vote may remain within such polling place. The local electoral board or general registrar and the chief officer for the polling place shall exercise authority over, but shall have no responsibility for the administration of, simulated election related activities at the polling place.
