Yes. Any leave of absence of three weeks or more, requires that you notify the board staff. Use the status change request form through the licensing portal to change your status to inactive. Be sure to renew your CSWA while in the inactive status. If you do not renew, your license to practice will expire and you will not be able to return to practice after your leave.
This also applies if your supervisor is taking a leave, you will need to notify the board to get a temporary supervisor approved, through an online plan change. You may not continue to be in active status if you are not reporting to work, or if you are not being supervised by your approved supervisor.
All leaves of absences result in an inactive status for the time of leave.
