Central Regional Dental Testing Service (CRDTS) is a national testing service that provides dental, dental hygiene and auxiliary testing to candidates from over 100 different dental and dental hygiene programs across the country. The CRDTS exams are recognized by over 40 states as a pathway toward initial licensure. CRDTS has three independent testing sites that allow candidates to schedule an appointment to take a licensure examination outside of the designated school time.
