Commencing in 1968, the Director of the Division of Taxation shall, annually, in March and September of each year, hold examinations of applicants for certification as tax assessor.

An applicant who does not meet the college education requirement may substitute full-time experience in real estate appraisal work or experience in property tax assessment work on a year-for-year basis. Such application shall not be considered by the director unless accompanied by payment of a fee in the sum of $10.00 to the order of the State Treasurer. Examinations shall be written, or both written and oral, shall be of such character as fairly to test and determine the qualifications, fitness and ability of the person tested actually to perform the duties of assessor, and shall be weighted in a manner to be prescribed by the director.
