When you check rehab staff qualifications, look at each person's credentials. Make sure they fit the job that person will actually do. A license, a certification, and a degree are not the same thing. Ask what each one covers. Then check any license with the state board or official source that issued it.
You also need to know who will evaluate and treat you. Find out who supervises trainees. Ask who is there if medical problems come up. Credentials and accreditation are helpful signs. But they do not prove a program is right for you.
This guide compares roles one by one. It also gives you a checklist for checking staff credentials yourself. For advice on weighing cost, location, and treatment approach, see our guide to comparing drug rehab programs.

What Kind of Staff Works at a Rehab Center?
When you compare treatment programs, it helps to know who is on the team. The staff mix depends on the services a program offers. A job title alone does not prove that someone holds a specific license.

credential categories to distinguish: license, certification and degree (guide framework, not workforce data)
5
common role groups shown below (guide framework, not workforce data)
2
separate checks to make: the individual's credential and the facility's accreditation (guide framework, not workforce data)
Use this table as a starting point. Requirements for some roles depend on your state and the exact job duties.
| Staff role | Credential or license to ask about | How to verify |
|---|---|---|
| Physician | State medical license; board certification if claimed | State medical board license lookup. Physicians in hospitals must be legally authorized to practice in that state.[1] Board certification is a specialty credential distinct from the state license.[2] |
| Other medical clinicians (e.g., Nurse Practitioner, Physician Assistant) | State license for that specific profession (e.g., nursing board for NPs) | State licensing board for that specific profession. Do not assume a medical board covers all clinicians. |
| Nurse | State nursing license (RN or LPN/LVN); specialty certification if claimed | State board of nursing license lookup |
| Licensed therapist, counselor or social worker | State clinical license (for example, LCSW, LPC, LMFT or psychologist license) | State licensing board website; often searchable by name. State rules define practice and supervision requirements for these roles.[3][4] |
| Addiction counselor | State credential such as LADC or LCDC; national certification like CADC or CCJP if listed | State addiction counseling board. For certifications like CADC, confirm the exact credential, issuing body, and jurisdiction, as requirements can vary. Note that national certifications (like NBCC's NCC) are voluntary additions to licensure, not replacements for a state license.[5] |
| Peer-support worker | State peer-support certification or training completion certificate (nonclinical role) | Program's stated training standards; state peer-support registry if available |
Organizations should have standards for staff qualifications based on the services they provide.[6] You can also check if the facility itself is accredited. CARF accredits behavioral health services using specific standards,[7] and The Joint Commission allows the public to search for accredited organizations.[8]
Licenses, Certifications, Degrees and Accreditation Are Different
When you compare treatment teams, you'll see several kinds of credentials. They aren't interchangeable. Knowing what each one means helps you ask better questions.
A professional license comes from state law. It allows a specific profession to practice. It also sets the scope of practice. For doctors, licensing is mandatory under state laws. It focuses on general requirements and basic competence.[2]
A certification is different. It usually shows that someone met a credentialing organization's standards. For physicians, ABMS board certification is a specialty credential. It stands apart from the state license needed to practice medicine.[2] A certification does not replace a license. Always check whether your state also requires a license for the role you're asking about.
A degree documents education. It tells you where someone studied and what they earned. A degree alone does not prove that the person holds a required professional license. You still need to confirm licensure separately.
Accreditation applies to a facility, program or service, not to an individual clinician. It signals that an outside body reviewed the organization against certain standards. To learn how to check this for a facility, see our guide to verify a rehab center's accreditation.
Certified Addiction Counselor Credentials
Addiction counselor titles and certification levels are not one nationwide license category. Requirements vary by state and by credentialing body, so the same job title can mean different things in different places.
For example, some states use titles like Licensed Professional Counselor (LPC) or Licensed Clinical Professional Counselor (LCPC) for independently licensed counselors, while others may use different acronyms or require additional steps for provisional licenses.[5] In some jurisdictions, a national certification like the National Certified Counselor (NCC) is a voluntary addition to licensure, whereas in others, specific state licenses are mandatory to practice.[5] These examples illustrate why you must check local rules; they are not universal standards.
When someone is described as a certified addiction counselor, ask for three details: the exact credential name, the issuing body, and the state or jurisdiction where it was awarded. That information lets you look up the record directly rather than relying on a job title alone.
Degrees and Specialty Certification
Consider a counselor who holds a master's degree in counseling and also lists a specialty certificate in trauma-informed care. Those credentials add useful information about their training and areas of focus. Still, they do not automatically confirm that the person holds any license your state requires for providing counseling services. Verify any required professional license separately through your state licensing board before you rely on it as proof of authorization to practice.
How to Verify Rehab Staff Credentials
Checking a single person's background takes a few minutes. It also protects your peace of mind. Don't rely only on a program's website. Also, don't trust just a bio the clinician sends you. Go directly to the source that issued the license or certification.
Start by asking the program for details. Ask for the staff member's full professional title. Ask for their credential type and the state or organization that issued it. Finally, ask what role this person will have in your care.
Once you have those details, visit the official website of the relevant state licensing board or credentialing body. Each profession has its own regulator, so there is no single database for everyone. For physicians, you can check the Federation of State Medical Boards directory or the specific state medical board. For nurses, use the Nursys license verification tool. For counselors and social workers, search the specific state board for professional counselors or social work in the state where the facility operates. National certifications, such as those from the NBCC, are distinct from state licenses and can be verified through the issuing organization's website.[5] Use their public licensee lookup tool to search for the person by name.
Compare the results carefully against what the program told you. Look for the correct credential type and ensure the status is active. Some boards also publish disciplinary actions or complaints, though these fields vary by state and profession.
If a record looks unclear or you cannot find the person, contact the issuing board or credentialing organization directly. They can confirm whether a license is valid and explain any public actions. Keep a note of where you looked and when you checked it. This simple record helps if questions come up later with your insurer or another provider.
While verifying credentials is important, it is just one part of choosing care. You should also look at other factors that affect quality and safety. Read our guide on warning signs of a bad rehab to see what else to watch for during your search.

Ask Who Provides, Supervises and Covers Your Care
Knowing a staff member's credential is only half the picture. You also need to know who will actually deliver your care. You need to know how trainees are supervised. And you need to know who covers after hours. Human-resources standards in healthcare settings generally expect organizations to determine the qualifications and competencies for all staff positions based on the type of care provided.[6]
- Ask who does each piece of your care. Find out who completes the check-in, who leads therapy, and who makes clinical decisions. Write down names and roles.
- Check each person's role and credential. Ask if the person giving your care is fully licensed or holds an associate or provisional credential.
- Ask who supervises trainees or provisionally licensed staff. If someone is working toward licensure, ask who oversees their work. Ask if that supervisor meets state requirements.[4] Some states require extra credentials before a clinician can supervise trainees.[4]
- Clarify after-hours coverage. Ask how to reach the right medical or clinical contact outside business hours. Ask what happens if your usual contact is unavailable. Get a phone number you can call at any hour.
These questions focus on care arrangements, not medical advice. For more conversation starters about working with your treatment team, see our guide to questions to ask rehab therapists.
What Facility Accreditation Can—and Cannot—Tell You
Accreditation reviews a whole organization, program or service. It checks the place against a set of rules. It does not check one person. For example, CARF accredits programs and services, including behavioral health services, using standards that apply to the program itself.[7]
Accreditation looks at the whole facility. It can show that the organization has rules for hiring, training and supervision. But it does not tell you if your specific nurse or counselor has a current license.
To verify a treatment center’s accreditation, ask two things. First, which group reviewed the site? Second, does that review cover the exact location and service you want?
Then, check each person’s credentials on your own. Look up each clinician in your state’s licensing database. This two-step process helps you see both the system around care and the people giving it.
Neither accreditation nor one credential guarantees good results. It does not promise quality or a good fit for you. Accreditation shows a facility meets certain benchmarks. Your comfort with the staff matters just as much. Their approach to your needs is key, too. Use accreditation as one piece of information, not the final answer.
Use Clear Answers to Compare Programs
Look for programs that can name who will treat you. Ask for their exact credentials. Find out who issued them. You need to know who supervises trainees. Also, ask how to reach staff after hours.
If a program cannot answer these questions, keep looking. You can compare drug rehab programs side by side. This helps you see which ones meet your standards.

This guide focuses on addiction treatment. The term "rehabilitation" is used in several fields, such as physical therapy or vocational training. Always check what kind of care a facility provides. The FAQs below briefly touch on employment questions, but this page is for people choosing treatment, not a careers guide.
Has the Program Answered Your Credential Questions?
This self-check is a planning tool only. It is not a quality rating or guarantee of care.
Frequently Asked Questions
How can I check whether a rehab therapist is licensed?
Ask for the exact title and license type. Then use the official lookup on your state board's website. If the title is psychologist, use your state's psychology board. Don't assume a general counselor lookup applies.
What is the difference between an addiction counselor certification and a clinical license?
A certification shows that a person met a credentialing body's requirements. It is not a state license to practice.[5] A clinical license comes from state law. It lets a person work within a set scope. Ask if the role needs both, and check each one with its issuing group.
Who provides medical care at a drug rehab?
This depends on the program's services and staff. Ask which licensed medical pros provide care, and how to reach them. For opioid treatment programs, federal rules require a medical director.[10] This person handles all medical services at the program.
Does accreditation prove that every staff member is licensed?
No, it does not. Accreditation looks at the whole organization or program, not each worker. Always check an individual's license with your state board. You can also look up the facility's accreditation status directly with the accreditor. The Joint Commission offers a public search called Quality Check for this purpose.[8]
What certifications or degree do you need to work at a rehab, and can you work there without a degree?
It depends on the job, employer, state, and whether the role gives clinical care. There is no single degree or certification needed for every job at a rehab center. Check the rules for that specific job and location instead of guessing.
What qualifications are required to become a rehabilitation specialist?
This title covers different jobs in different places, so first find out which occupation you mean. Then compare education needs for that specific role and setting. For addiction treatment, look at counselor, clinical, medical or peer-support rules instead of assuming one general title applies everywhere.
What are the four main types of rehabilitation?
Classifications vary by field, but common categories include physical, occupational, speech, and cognitive rehabilitation. These focus on restoring function after injury or illness. Addiction treatment is distinct from these medical rehabilitation types, though it is often referred to colloquially as "rehab." This guide uses "rehab" to mean addiction treatment only.
