The Office of Professional Examination Services provides psychometric consulting services for the management of occupational licensure examination programs. OPES’ services include occupational analysis, item writing, examination development, standard setting, program evaluation, and statistical analysis of examination performance. OPES follows the highest technical and professional standards in the industry to ensure that licensing examinations are valid, job-related, and legally defensible. In addition to servicing 30—40 interagency contracts with DCA boards, bureaus, and committees, OPES also oversees the master contract for examination administration at computer-based testing centers throughout the State. In June 2013, OPES implemented a new master contract with PSI Services LLC, resulting in cost savings of 10 percent for its clients that use the contract.
