The board shall prescribe a written examination to determine the proficiency of the applicant. If the applicant passes the examination and meets the other requirements of section 76-542, the board shall issue a certificate of registration designating him or her to be a registered abstracter. If the abstracter has more than one place of employment, the abstracter shall obtain a duplicate certificate of registration for each additional place of employment. A certificate shall be prominently displayed at each place of employment of such abstracter. If an applicant fails the examination, he or she may reapply for registration by remitting the examination fee. The board shall give the examination at least twice a year.
