Who can apply

The Co-Occurring Disorder Specialist is an enhancement available to be added to the license of specific counselors under RCW 18.205.105 (1) which allows them to provide substance use disorder treatment with some limitations. It is not available as a stand-alone credential. Applicants must already possess one of these qualified credential types to be eligible to apply and maintain the credential to continue providing co-occurring disorder services.

Online Application Instructions

See the online application video.

Online application instructions are on our website. Online applications are accessed through Secure Access Washington (SAW) security portal. You'll need to add the Department of Health Online Application 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 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 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.

If you completed the approved education course and are requesting approval to sit for the exam before completing the supervised hours, you'll need to contact the course provider for approval.

Education and Experience


To obtain the co-occurring specialist applicants must complete a 60-hour training course specifically relating to substance use treatment and approved by the department. Other training courses and college courses do not count toward the requirements. It is the completion of a specific individual course. Not an aggregate of courses.

The training course consists of 30 hours in understanding the disease pattern of addiction and the pharmacology of alcohol and other drugs; and 30 hours in understanding addiction placement, continuing care, and discharge criteria including the American Society of Addiction Medicine (ASAM) criteria; treatment planning specific to substance abuse; relapse prevention; and confidentiality issues specific to substance use disorder treatment.

Supervised Experience Requirement

The experience requirement for a Co-Occurring Disorder Specialist enhancement consists of:

  • 80 hours of supervised experience for an applicant with fewer than 5 years of experience under their primary license; or
  • 40 hours of supervised experience for an applicant with more than 5 years of experience under their primary license.

Approved Supervisor

To meet the educational component of the co-occurring specialist, the applicant must obtain experience hours under a licensed Substance Use Disorder Professional or someone who meets the requirements to become an SUDP and would be eligible to take the exam required for certification.

Education Providers

To obtain the co-occurring specialist enhancement, applicants must complete a department-approved 60-hour training course specifically relating to substance use treatment.
