How to Verify a Social Worker License

Understanding social work license levels

Social work licensing is state-regulated and varies in structure and title across jurisdictions. However, most states recognize a multi-tier system based on the ASWB (Association of Social Work Boards) licensing examinations:

• LSW / Associate (LBSW, LGSW) — entry-level, based on a bachelor's or generalist-level master's degree. Scope of practice is supervised and limited.
• LMSW (Licensed Master Social Worker) — requires an MSW from a CSWE-accredited program and passing the ASWB Master's examination. May practice under supervision.
• LCSW (Licensed Clinical Social Worker) — requires an MSW, postgraduate supervised clinical hours (typically 2–3 years), and passing the ASWB Clinical examination. Authorized for independent clinical practice, psychotherapy, and diagnosis.
• LCSW-C / ACSW / advanced designations — additional specialty or advanced certifications issued by some states or the National Association of Social Workers (NASW). These are supplemental to, not substitutes for, state licensure.

Verify that the license level matches what the role requires. A candidate holding an LMSW cannot independently practice clinical social work in most states — roles requiring independent clinical practice or psychotherapy require LCSW-level licensure.

Step 1: Search the state licensing board

Each state's social work licensing board maintains a public license lookup that shows current license status, level, and expiration. This is the authoritative source for confirming active licensure.

How to find the right state board

Search "[state name] social work licensing board license lookup" or visit the ASWB member board directory at aswb.org/licensees/member-boards for direct links to every state's licensing board. Most state boards offer free public name searches that display license type, expiration date, status, and any disciplinary actions.

What to confirm in the state board lookup

1. License is active, not expired, suspended, or revoked
2. License level matches what the position requires (LSW vs. LMSW vs. LCSW)
3. Expiration date is current (most states renew every 2 years)
4. No disciplinary actions, conditions, or supervisory requirements attached
5. License number matches the documentation the candidate provided

Step 2: Understand ASWB's role in licensing

The Association of Social Work Boards (ASWB) develops and administers the licensing examinations used by the vast majority of US states and Canadian provinces. Passing an ASWB exam is required for licensure — but ASWB does not issue licenses. Licenses are issued by state boards.

ASWB does not maintain a public verification database of licensed social workers. Some candidates may present ASWB exam pass letters as evidence of qualifications — these confirm exam passage only, not that a license was actually issued. Always verify the license directly with the state board.

NASW membership vs. state licensure

The National Association of Social Workers (NASW) offers voluntary membership and credentials including the Academy of Certified Social Workers (ACSW) and Certified Clinical Social Worker (CCSW) designations. These are supplemental credentials — they demonstrate professional involvement and meet additional standards, but they are not substitutes for state licensure. Verify the state license regardless of NASW designations.

Step 3: Verify the social work degree and program accreditation

Social work licensure requires a degree from a program accredited by the Council on Social Work Education (CSWE). CSWE accreditation is the standard for both BSW (bachelor's) and MSW (master's) programs in the United States. A degree from an unaccredited program will not satisfy state licensure requirements in most jurisdictions.

Verify CSWE accreditation

Check CSWE program accreditation at cswe.org/accreditation/directory. The directory lists all accredited BSW and MSW programs by institution. As with other professional accreditors, CSWE accredits specific programs — not entire universities. A school may be regionally accredited without having a CSWE-accredited social work program.

Degree conferral verification

Verify the actual degree award via the National Student Clearinghouse DegreeVerify or directly with the institution's registrar. Confirm degree title (BSW or MSW), conferral date, and that the program attended was CSWE-accredited at the time of graduation — some programs lose accreditation after students have already enrolled.

7 red flags in social work credentials

1. License not found in state board lookup — active licenses appear in public databases. A candidate who claims licensure but cannot be found in the state board system should not proceed until the discrepancy is resolved.
2. License level doesn't match the role — LMSW and LCSW are substantively different. An LMSW cannot independently provide clinical services in most states. Confirm the level, not just that a license exists.
3. Expired license presented as current — social work licenses expire every 1–2 years depending on state. An expired license means the candidate has either let continuing education lapse or has not maintained active status. Verify the expiration date directly in the state board lookup.
4. Disciplinary action or supervisory conditions — state boards publish enforcement actions. A license with conditions (required supervision, restricted scope of practice, probation) affects what the candidate can legally do in your setting.
5. Degree from a non-CSWE-accredited program — an MSW from an unaccredited online school does not qualify a candidate for clinical licensure. Verify CSWE accreditation before treating the degree as meeting licensure requirements.
6. Presenting NASW credentials as equivalent to state licensure — ACSW, CCSW, or other NASW designations are supplements to state licensure, not substitutes. A candidate without a state license who presents only NASW credentials is unlicensed regardless of those designations.
7. Gaps in supervised hours for LCSW candidates — LCSW candidates are required to complete 2–3 years of postgraduate supervised clinical hours. Verify with prior employers that the supervision actually occurred under a qualified LCSW or equivalent.
