An examination of each applicant for a master plumber's journeyman or apprentice plumber's
license shall be conducted by the board of plumbing examiners and appeals at a time
and place determined by such board. The examination may be written or oral or a combination
of both, at the discretion of the board, and shall, in each instance, be of such nature
as to satisfy the board as to the applicant's proficiency in the art of plumbing and
plumbing installations and his knowledge of the provisions and material requirements
of this chapter, Chapters 2.92 and 16.12, and any subsequent amendments made thereto, as such are related to the applicant's
request for licensing; except, that no written examination shall be required of any
applicant for a metropolitan apprentice plumber's license.
B.
Notwithstanding any other provision to the contrary, any person who is unable to read
and write shall be given an oral examination for master plumber, journeyman, or apprentice
plumber's license.
