Search for an ADHD provider in Washington and you get psychiatrists, psychologists, neuropsychologists, physician assistants, nurse practitioners, primary care physicians, and therapists, with no explanation of how they differ. Most people pick based on which website loaded fastest.
The distinction that actually matters is not the prestige of the credential. It is that diagnosing and prescribing are separate authorities in Washington, and some professions hold one without the other.
Who Can Prescribe
The Washington State Department of Health publishes a list of professions that may prescribe and what limits apply to each. Physicians may prescribe with no restriction. Advanced registered nurse practitioners may prescribe with no restriction. Physician assistants may prescribe as approved by the Medical Commission.1
Psychologists do not appear on that list. In Washington, a psychologist can evaluate you, test you, and diagnose you, and cannot write you a prescription. That is not a comment on their expertise. It is how the licence is drawn in this state. A handful of states have created prescribing pathways for psychologists with additional training. Washington is not one of them.
The practical consequence is worth being clear about, because it costs people months. If you pay for a full neuropsychological evaluation with a psychologist and the conclusion is ADHD, you then need to find a prescriber and, in most cases, be evaluated again by that prescriber before anyone writes anything. That sequence is sometimes exactly right. It is a bad surprise if nobody mentioned it.
What a PA Can and Cannot Do Here
People ask this about Clarity ADHD, and the honest answer is in the rules rather than in reassurance.
Washington's rule on physician assistant prescribing says a PA may "prescribe, order, administer, and dispense legend drugs and Schedule II, III, IV, or V controlled substances consistent with the scope of practice," on two conditions: that the physician assistant holds an active DEA registration, and that all prescriptions comply with state and federal prescription regulations.2 Stimulants are Schedule II. A Washington PA with an active DEA registration can prescribe them. For the narrower prescribing question, see whether a PA can prescribe ADHD medication in Washington.
PAs practise under a collaboration agreement with a participating physician. State law sets out what that agreement has to contain: the duties and responsibilities of both, a limitation that the work fall within the scope and clinical practice of the participating physician, a defined process for communication, availability, and decision making, a named backup physician for when the primary one is unavailable, and an attestation of the PA's postgraduate clinical hours.3
What this does not mean is a physician reviewing each of your visits. What it does mean is a defined clinical relationship, a documented scope, and a named person to consult. If that matters to you, ask any practice who their collaborating physician is. It is a fair question and there is no good reason to dodge it.
What Therapists Do, and Do Not Do
Licensed mental health counselors, clinical social workers, and marriage and family therapists provide therapy, and for ADHD that is often genuinely valuable, particularly for the executive function and organizational side that medication does not touch.
They cannot prescribe in Washington. If you are working with a therapist and medication is the question, you need a prescriber alongside them rather than instead of them. Good ADHD care frequently involves both, and the two should be talking to each other.
So Which One Should You Actually Book?
Work backwards from what you need rather than forwards from the credential.
If you want a diagnosis and, if appropriate, medication managed by the same person over time, you need a prescriber: a psychiatrist, a physician assistant, an ARNP, or a primary care physician who is comfortable with adult ADHD. Many are not, and a PCP who says so is doing you a favor.
If a learning disorder, a memory problem, or something genuinely tangled is in play, or you need formal documentation for accommodations, testing with a psychologist or neuropsychologist is what buys you that, and you will need a prescriber afterwards if treatment follows. What each route costs in Washington differs by more than a factor of ten, which is worth knowing before you choose.
If you are already diagnosed and just need care to continue, what you need is a prescriber who will take a transfer without making you start from zero.
Two Things Worth Checking on Anyone
First, the licence. Washington's Department of Health runs a public credential search, and it takes about a minute to confirm that a provider holds a current Washington credential and to see any disciplinary history. Any legitimate practice will give you their licence number without being asked, and ours is on the about page.
Second, that they are licensed in Washington specifically. For telehealth this is the whole ballgame, because a provider must be credentialed here to treat you while you are located here, with only narrow exceptions for consultation, specialty assessment that does not include treatment, and continuity of care for someone temporarily in the state.4 A national telehealth brand with clinicians spread across the country is not automatically wrong, and it does mean the person you see must still be licensed in Washington.
Beyond that, the letters after someone's name predict much less than how they work. The questions that separate good ADHD care from the other kind are how long the first appointment is, whether anyone screens for the conditions that imitate ADHD, what happens when the first medication does not suit you, and whether you see the same person next time.
