  • We don't charge renewal fees to credential holders in active military status.
  • If the credential holder doesn't submit current orders on the renewal, the credential expires.
  • We'll change a military status to active when the service member:
    • Provides a copy of the discharge papers (DD214).

  • Continuing education hours, if applicable, aren't required upon return to active status.
