Examinations shall be of such character as fairly to test and determine the qualifications, fitness and ability of competitors actually to perform the duties of the classification for which they seek licenses. Examinations may be assembled or unassembled, written or oral, or in the form of a demonstration of skill, or any combination of these; and any investigation of character, personality, education and experience and any tests of intelligence, capacity, technical knowledge, manual skill, or physical fitness which the Secretary deems are appropriate, may be employed.

A candidate who holds a valid commissioner or sealer license may qualify for the other license by obtaining the appropriate deputy license and passing an oral examination.
