The Central Regional Dental Testing Service, Inc. (CRDTS) is a testing service made up of seventeen State Boards of Dentistry who have joined forces to develop and administer fair, valid and reliable examinations of competency to practice dentistry and dental hygiene. The members of CRDTS are the State Boards of Colorado,  Georgia, Hawaii*, Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, New Mexico, North Dakota, South Carolina, South Dakota, Washington, West Virginia,Wisconsin, and Wyoming.  (For more information on the State Boards, please visit the Contacts Page.)  *Accepts CRDTS Hygiene Only

Part of the initial motivation to form Regional Boards was an effort to keep the responsibility for competency assessment in the hands of dental professionals rather than a government bureaucracy, and to enable State Boards to improve their testing methodologies. By pooling their resources, states are able to secure personnel with more expertise in tests and measurements, broaden the geographic base of the examination and offer the examination in more modern clinic facilities. The advantage to candidates is access to licensure in more states through successful completion of a standardized, objective, valid and reliable examination. More recently, there has been a great deal of national collaboration towards more uniformity in clinical licensure examinations.

CRDTS is one of five regional boards, or regional testing services, in the country: the Northeast Regional Board-NERB ; the Central Regional Dental Testing Service, Inc.-CRDTS; the Southern Regional Testing Agency-SRTA; Council of Interstate Testing Agencies - CITA; and the Western Regional Examining Board-WREB.
