Examinations of applicants for a license to practice psychology shall be conducted by the board at least once a year. The examinations shall be written or oral or both. In any written examination such applicant shall be designated by a number instead of his name so that his identity shall not be disclosed to the members of the board until the examination papers have been graded. The board shall establish a passing score for the written examination. A candidate shall be held to have passed the oral examination upon the affirmative vote of a majority of board members currently serving. Any unsuccessful candidate shall receive written evaluation of his performance on the oral examination.
