Peer Support Specialist Certification in Washington: Training, Hours and Medicaid Rules

Washington's credential is the Certified Peer Support Specialist, issued by the Department of Health since July 1, 2025, with a Certified Peer Support Specialist Trainee certificate below it.

They replace the certified peer counselor credential the Health Care Authority used to certify.

Becoming certified is voluntary except as RCW 71.24.920 provides: you can practice peer support services without the credential, and the statute forbids using the title certified peer support specialist without holding it, but an entity that uses certified peer support specialists as peer crisis responders may only use those who completed HCA's 40-hour crisis response training course.

The statute defines the practice as interventions delivered by a person in recovery, or a youth's parent or legal guardian, to a person with a similar lived experience.

Certification starts with an attestation, not a diagnosis or a treatment history: you self-identify under a route you choose.

The recovery route is one or more years of recovery from a mental health condition, a substance use disorder, or both.

The family route has no recovery-duration clock: it is for the parent or legal guardian of a youth who is receiving or has received behavioral health services.

The statute's definition of the practice of peer support services mirrors the same two identities, so the attestation is the doorway to the credential rather than a formality attached to it.

The course of instruction is developed and offered by the Health Care Authority, and the statute sets its length as approximately 80 hours.

It builds on HCA's peer counselor curriculum as it existed on July 23, 2023, adds instruction in recovery coaching and suicide prevention, and must be taught by certified peer support specialists.

HCA must offer it in multiple configurations, including an accelerated consecutive-day format and an extended format for students with other commitments.

This course sits inside the chapter's default route: RCW 18.420.050(1) opens 'except as provided in subsections (2) and (3) of this section', and subsection (3) issues the full certificate on completing an apprenticeship program registered and approved under chapter 49.04 RCW — a route the statute does not tie to subsection (1)'s course, exam and hours list; what the apprenticeship itself requires was not in the sources read.

HCA also runs an expedited course covering only the material beyond the old peer counselor training.

The experience requirement is 1,000 supervised hours as a certified peer support specialist trainee, and the statute counts both volunteer and paid practice toward it.

The trainee certificate carrying those hours is valid for one year and may only be renewed four times, so count your hours against that clock before you take a trainee job.

A trainee may practice only under an approved supervisor, and the chapter is explicit that supervision can come through the employer, through a third-party approved supervisor arranged outside it, through distance supervision, or a combination of these.

RCW 18.420.050(1)(c)-(d) requires an oral examination and a written examination upon completion of the education course and names the Health Care Authority as the administrator of both.

The course statute puts the oral exam in different hands: RCW 71.24.920(1)(a) requires the student, upon completing the course, to pass an oral examination administered by the course trainer.

For the written exam, RCW 18.420.070 puts its dates, places and grading with HCA and limits the exam to the minimum skill and knowledge needed to practice competently.

The retake rule is explicit: after a failed first written examination you may take up to three subsequent exams, prepaying an HCA-set fee for each, and after four failures HCA may invalidate the original application and require remedial education.

HCA may also approve a written exam prepared by a private organization that credentials peer counselors.

RCW 18.420, read in full for this page, contains no background-check requirement, no disqualifying-offense list and no look-back period for peer certification applicants.

What the chapter does say is that the uniform disciplinary act, chapter 18.130 RCW, governs uncertified practice, the issuance and denial of certificates, and the discipline of certified peer support specialists and trainees — and chapter 18.130 was not part of the sources read.

DOH's implementing WAC rules were also not read.

That leaves the practical criminal-history question unanswered by the statutory text, so ask the Department of Health how a record affects an application before you apply.

Peer support is an Apple Health (Medicaid) service, and HCA's consumer page says plainly that peer counseling is an approved Medicaid service in Washington.

That page still describes the workforce as certified peer counselors, the pre-2025 wording.

What the sources read do not state is the vehicle: the federal authority behind the benefit and the billing rule were not located, so confirm billing mechanics with HCA rather than assuming them.

When the legislature created the credential, its finding was that peers were limited to serving only Medicaid recipients and working only in community behavioral health agencies — the gap the new chapter is meant to close.

For a trainee, only an approved supervisor counts, and the definition has two routes.

Route one is written to expire: until July 1, 2028, a behavioral health provider as defined in RCW 71.24.025 with at least two years of experience working in a behavioral health practice that employs peer support specialists or certified peer counselors as part of treatment teams.

Route two is the peer-led one, quoted below, which survives the sunset.

Supervision can run through the employer or a third-party arrangement, and distance supervision is allowed.

For billed services, HCA's page describes certified peer counselors working under the supervision of a behavioral health professional as part of a health care team.

DOH must report to the legislature by December 1, 2027 on whether the supervisor supply can meet trainees' needs once the provider route expires.

There is no private board in this credential's chain: the Department of Health issues the certificate directly, so moving to Washington runs through DOH's equivalency power.

The secretary determines which states have credentialing requirements equivalent to Washington's and can issue certificates to applicants credentialed in those states without examination.

That is a state-by-state determination DOH makes; the sources read do not list which states qualify, so ask before you relocate.

Two exemptions sit alongside it: holders of another Washington credential can practice their own occupation without the peer credential, though they may not use the certified peer support specialist title, and people employed by the federal government practicing under federal duties are outside the chapter.

A certificate is valid for two years.

Renewal takes 30 hours of continuing education approved by the department, and inside that requirement sits a six-year cycle, quoted below.

Letting the certificate lapse invalidates it and the privileges it grants, and a lapse longer than three years means demonstrating competence to the department through continuing competency or other standards it sets.

Fees for certification, examination and renewal are set by the secretary of health.

Two session laws built this system: 2023 c 469 created the profession and 2025 c 360 amended it.

Certification opened on July 1, 2025, with title protection from the same date.

Under RCW 18.420.050(2), applicants qualifying on pre-July 2025 peer experience had until July 1, 2026 to complete any standards where they were found deficient; the sources read do not say what applies to such applicants after that date.

Still ahead, the behavioral-health-provider route to approved supervisor ends July 1, 2028, and DOH must report to the legislature on the supervisor supply by December 1, 2027.

DOH's credential page still says more information is coming soon, and its WAC rules were not part of the sources read.
