Primary Source Verification
PSVHealthcare credentialing, staffing agencies
Confirming a professional's credentials directly with the issuing authority (state board, certification body, or institution) rather than relying on self-reported documents. Required by accreditation bodies including The Joint Commission (TJC) and NCQA. Typically performed via the state board's public license lookup portal.
Social work license tiers
Licensed Bachelor Social Worker
LBSWSocial work
The entry-level social work license issued to graduates of a CSWE-accredited bachelor of social work (BSW) program. Scope of practice is limited compared to master's-level licenses — LBSWs typically cannot provide independent clinical services or bill insurance for therapy. Not all states offer the LBSW credential.
Licensed Social Worker
LSWSocial work
A social work license issued to graduates of a CSWE-accredited master of social work (MSW) program who have passed the ASWB bachelor or master examination. LSWs can provide non-clinical social work services but typically cannot independently provide clinical therapy or bill insurance for mental health services. Scope and title vary by state (some states use LMSW).
Licensed Clinical Social Worker
LCSWSocial work, mental health
The highest clinical social work license, requiring an MSW degree, passage of the ASWB clinical examination, and typically 2–3 years (3,000–4,000 hours) of post-MSW supervised clinical experience. LCSWs can independently diagnose and treat mental health conditions and bill insurance for clinical therapy. Billing compliance requires an active LCSW license — a lapse stops Medicaid and insurance billing immediately.
Supervision Hours
Social work, clinical mental health
Post-degree supervised clinical hours required before a social worker can apply for clinical licensure (LCSW). Requirements typically range from 2,000 to 4,000 hours depending on state, with a minimum number of hours in direct client contact and a minimum under individual (not group) supervision. Supervision must be provided by a qualified licensed supervisor. Hours must be documented contemporaneously — retroactive documentation is not accepted.
