An applicator's certification shall automatically renew under the classification or subclassification for which such applicator is certified; provided, however, reexamination may be required by the Department:
Such reexamination or special examination requirements may be waived by the Department when the applicator can furnish satisfactory evidence of completion of educational courses, programs or seminars approved by the Department relating to the applicator's certification.
