The Board will provide you with the new dates once it is clear when the exam can be administered in a safe environment and when travel restrictions are eased for all participants.  We regret that this decision had to be made, but we feel it was necessary for the safety for all involved.  If you would like a refund, please contact the Board at and one will be issued.
