Obtaining a dental assistant license requires getting certified by the Dental Assisting National Board or DANB which is recognized across the US. To be eligible to do the DANB examinations a prospective examinee needs to complete a course from an accredited institution conducting a dental assisting education program. Entry in to such programs requires the minimum academic level of a high school diploma or equivalent. Specific programs may require the applicant to have studied science (chemistry and biology) and/or computers in high school to be eligible for admission. Alternatively, he/she needs to have relevant working experience as a dental assistant either full time for two years or part time for four years.
