The Washington State Department of Health requires that only the applicant or licensee may complete an attestation for an application, or for continuing education. This is a legal attestation. Completion of the attestation by anyone other than the applicant may constitute a reportable felony offense. The Department of Health can take action against people for perjury or for making a false statement they know to be false.

For further information please see:

Washington State law authorizes the Department of Health to obtain fingerprint-based background checks for licensing purposes. This check may be through the Washington State Patrol and the Federal Bureau of Investigation. We may require this if you have lived in another state or if you have a criminal record in Washington State. This would be at your own expense.

You must pay the application fee at the time you apply. You may use a credit or debit card with a VISA or MasterCard logo, or pay by ACH/E-Check. Please make sure your address on the payment information screen matches the address your financial institution has on file for you. This fee is non-refundable. There is a convenience fee to apply online.

If we need additional documentation, we'll notify you by email.

Getting started

Online Application Instructions

Online application instructions are on our website.

Online applications are accessed through SecureAccess Washington (SAW) security portal. You'll need to add the Department of Health Online Application Portal - Healthcare Enforcement and Licensing Management System (HELMS) Portal service to access the online applications. The first time you add the service, you'll be prompted to answer several questions to verify your identity. The questions will match the name and address you provide with the existing public record information. Because the questions come from public record, you need to provide a complete address and your full legal name as it appears on your driver's license or birth certificate. You may find you have to enter a former address, especially if your address has changed recently (within the past one or two years) to get the right questions that pertain to your identity. If you don't have sufficient information in the public record to verify your identity and aren't currently credentialed by the Department of Health, then you'll need to submit a paper application, as you won't be able to access the Online Application Portal.

Once you have completed the process, and submitted your application, you will receive an email with your pending credential number, or you may look on Provider Credential Search. Refer to this credential number any time you contact Department of Health or submit paperwork.

State license verification

Applicants must list all states where they do or did hold credentials. This list must also include when the applicant has applied for a credential, even if a credential was not granted. The jurisdiction where the applicant is or was credentialed must complete and submit the verification form (PDF). The jurisdiction must send the completed form directly to the department.

Personal data questions

Each applicant must answer the personal data questions. An appropriate explanation and required documentation must be sent with positive answers. If there is a positive answer to the professional liability claims history question, the applicant must send an explanation of the nature of the case, data and summary of care given, copies of the original complaint, and the settlement or final disposition. If the case is pending, applicant must indicate status.

Process for approving/denying applications

We finish final review for approval after a credentialing specialist verifies that the application is fully complete, and complies with requirements in chapter 18.260 RCW and chapter 246-817 WAC. We complete background checks and make sure applicants have submitted required fees. Credentialing supervisors and lead workers have the authority to approve routine applications. The disciplining authority may conduct further review if the credentialing supervisor can't verify the applicant meets all requirements. We'll formally notify applicants of a denial. Those applicants may request a hearing to appeal the decision.

Renewal requirements

Expanded function dental auxiliaries must renew their license every year. Credentials expire on the credential holder's birthday and may be renewed within 90 days of the expiration date. A courtesy renewal notice will be mailed to your address on record. You must keep your address current with us. Any renewal postmarked or presented to the department after midnight on the expiration date is late.

Continuing education requirements

There are no continuing education requirements.
