Preparation Formal training is not required for dental assistants. Thus some dental assistants learn their skills on the job. However, many assistants receive training at community colleges, trade schools, or technical institutes. Most programs take less than a year to complete. These programs lead to a diploma or certificate.
Associate degrees are available after completion of a two-year program.
Both types of programs include classroom study and supervised clinical work. A high school diploma or GED is required for admission to these programs. Some programs require that applicants have taken typing or science courses. Suggested high school courses are biology, chemistry, health, and office practices. A few states require assistants who take X-rays to be certified.
