Getting started as a dental assistant in Washington is straightforward once you know the requirements. You need the right training, knowledge of state rules, and preparation for certification. The first step is choosing a school that will prepare you for the job and help you meet the state's licensing standards.

This guide covers the best dental assistant schools in Washington, what to look for, and the steps you'll take to get certified.

State Requirements for Dental Assistants in Washington

In Washington, dental assistants can start working without formal licensing, but certain advanced duties require additional credentials. Expanded Function Dental Assistants (EFDAs) must complete extra training and pass exams approved by the Washington State Department of Health.

According to the Washington State Department of Health, "Dental assistants may perform basic supportive procedures under the close supervision of a licensed dentist. To place fillings or perform other advanced functions, EFDA certification is required." 1

If you plan to advance in your career, choosing a program that covers these expanded duties will save you time later.

  • State Exam Preparation: If you plan to become an EFDA, the program should prepare you for the Washington state EFDA exam.
  • Scheduling Options: Look for day, evening, or part-time schedules if you're working while in school.
  • Employer Partnerships: Schools with connections to local dental offices often have higher job placement rates.

These skills are important both for entry-level work and for moving into advanced roles like EFDA.

Continuing Education and Career Growth

Once registered, you'll need to keep your training current. The Washington State Department of Health may require continuing education for certain endorsements.

Advanced certifications, like EFDA or dental radiography endorsements, open doors to higher responsibility roles. Some dental assistants also go on to become dental hygienists, office managers, or trainers.

Final Advice

If you want to work in dentistry without spending years in school, dental assisting is a smart path. Washington has many excellent programs that mix classroom learning with real clinic time.

Start by deciding if you'll aim for the EFDA level. Then choose a CODA-accredited program that fits your schedule, budget, and career plans. Contact the admissions departments for details, application deadlines, and financial aid options.

  1. Pick two or three schools from the list above.
  2. Visit their campuses or attend an info session.
