Examinations for a license shall be given as often as deemed necessary by the real estate commission, but no less than one time per year. Each applicant for a license must pass an examination authorized by the commission and administered by the commission or persons designated by the commission. The examination shall be of scope and wording sufficient in the judgment of the commission to establish the competency of the applicant to act as a real estate broker or salesperson in a manner to protect the interests of the public. An examination for a real estate broker shall be of a more exacting nature than that for a real estate salesperson and require higher standards of knowledge of real estate. The identity of the persons taking the examinations shall be concealed until after the examination has been graded. A person who fails to pass either examination once may immediately apply to take the next available examination. Thereafter, the applicant may take the examination at the discretion of the commission. An applicant who has failed either examination may request in writing information from the commission concerning the applicant’s examination grade and subject areas or questions which the applicant failed to answer correctly, except that if the commission administers a uniform, standardized examination, the commission is only required to provide the examination grade and other information concerning the applicant’s examination results which is available to the commission.
