(1) Worker and supervisor certificate renewal is valid for two years from the date of issuance. All worker and supervisor certificates issued after December 1, 2009, will expire on the same day: November 30, 2011, and on November 30th in every odd-numbered year thereafter. Certification fees will be prorated by the month for applications submitted during the two-year period.

(2) Certified workers and supervisors seeking certificate renewal shall submit to the department thirty or more days before expiration of the current certificate:

(a) A completed application form for certificate renewal;

(b) A fee prescribed in WAC 246-205-990; and

(c) Evidence of successful completion of a department sponsored or approved refresher training course.

(3) If a worker or supervisor fails to renew his or her certificate before it expires, the department shall notify the worker or supervisor that the certificate is temporarily valid for sixty days beginning on the expiration date of the worker's or supervisor's certificate.

(4) If a worker or supervisor renews his or her certificate during the sixty-day period, he or she shall pay the full two-year certificate renewal fee.

(5) If the worker or supervisor fails to renew the certificate within the sixty-day period, the certificate is invalid. The department shall notify the worker or supervisor in writing of an invalid certificate.

(6) A worker or supervisor who fails to renew his or her certificate while it is valid may reapply for certification, but must meet the requirements for a previously certified worker or supervisor established in WAC 246-205-071.
