What Is the NASW? The National Association of Social Workers Explained
The NASW, or the National Association of Social Workers, is the world’s largest membership organization for professional social workers, with approximately 120,000 members in the United States. Founded in 1955, it sets professional standards, publishes the field’s Code of Ethics, advocates for policy, and offers specialty credentials that help social workers build their careers.
Every licensed social worker in the country is typically held to an ethical framework heavily influenced by the NASW Code of Ethics, which most state licensing boards reference or adopt in their standards. That’s the clearest way to understand what this organization is and why it matters, not as a professional club, but as a major body that helps define what professional social work looks like in practice.
What the NASW Does
The National Association of Social Workers serves its members and the profession in four main ways: setting professional standards, publishing educational and practice resources, advocating for public policy, and offering credentials that go beyond state licensure.
NASW is built on a membership base, but its influence extends well beyond its members. The Code of Ethics informs how licensed social workers are expected to practice and is widely used by state licensing boards in their standards and disciplinary processes. The same is true of NASW’s policy advocacy: when the organization takes a position on mental health funding or workforce conditions, it advocates on behalf of its membership and often represents the broader profession in national policy discussions.
NASW also operates chapters across all 50 states, Washington, D.C., and a small number of international affiliates. These chapters handle continuing education events, local advocacy, and member networking at the state level, giving the organization both a national policy voice and a local professional presence.
The NASW Code of Ethics
The NASW Code of Ethics is the document the profession runs on. First adopted in 1960, it sets out the values, principles, and standards that define ethical social work practice. State licensing boards reference it. Graduate programs teach it. Ethics complaints against licensed social workers are measured against it.
The Code includes a Preamble, a statement of purpose, a set of core ethical principles, and detailed ethical standards covering responsibilities to clients, colleagues, practice settings, the profession, and society. The Preamble summarizes the social work profession’s mission and its core values: service, social justice, dignity and worth of the person, the importance of human relationships, integrity, and competence. The ethical standards section is the most detailed, and it’s the part practitioners and licensing boards consult when specific questions arise in the field.
The Code was revised in 2017 and has been updated since, including additions addressing technology, self-care, and evolving practice standards. It is widely applied across the profession and incorporated into many state licensing standards, with enforcement handled through state boards rather than NASW directly. Licensing in the U.S. is administered state by state through boards overseen by the Association of Social Work Boards (ASWB), which develops the licensing exams and supports regulatory consistency across states.
NASW Credentials and Certifications
State licensure tells an employer that a social worker has met the minimum requirements to practice. NASW credentials go further. They signal specialized expertise in a particular population or practice area, and they’re voluntary, typically requiring a combination of supervised experience, continuing education hours, and application review.
NASW’s credential offerings include certifications for case management at both the BSW and MSW levels, school social work, and practice with military families, among others. The organization also maintains Specialty Practice Sections, member communities organized around specific fields like aging, behavioral health, child welfare, and school social work. These aren’t credentials, but they connect practitioners to field-specific CE resources and peer networks that can support career growth in a particular area.
How NASW Is Governed
NASW is a member-driven organization. Its highest governing body is the Delegate Assembly, made up of delegates elected by the membership across state chapters who set the organization’s overall policy direction and priorities. Day-to-day operations fall to a Board of Directors, also elected by the membership.
This structure matters because it means the positions NASW takes on workforce conditions, mental health funding, social justice policy, and professional standards reflect the priorities of working social workers, not appointed officials or outside interests. When NASW advocates before Congress or issues a policy statement, it does so with a mandate from its membership.
Why NASW Membership Matters for Your Career
NASW membership isn’t required to practice social work. But for practitioners who want to stay current, build credentials, or connect with the field beyond their own workplace, it’s worth knowing what membership actually provides.
Members get access to discounted continuing education credits, the NASW Career Center, and the Legal Defense Fund, a resource that provides consultation and support when practitioners face licensing complaints or workplace legal issues. That last benefit is one many social workers don’t think about until they need it. For students and early-career practitioners, NASW offers reduced membership rates and access to professional development resources that can help bridge the gap between graduate training and full-time practice.
Frequently Asked Questions
Is NASW membership required to practice social work?
No. NASW membership is voluntary. State licensure (through your state’s social work licensing board) is what authorizes you to practice. NASW membership provides professional development resources, credentials, networking, and advocacy, but it isn’t a legal requirement for employment or licensure in any state.
What is the NASW Code of Ethics and who does it apply to?
The NASW Code of Ethics covers how social workers should handle client relationships, confidentiality, professional boundaries, conflicts of interest, and responsibilities to the broader community. It is widely applied across the profession and incorporated into many state licensing standards, though legal enforcement is handled by state boards rather than NASW directly.
How is NASW different from a state licensing board?
NASW is a voluntary professional membership organization. State licensing boards are government agencies that regulate who can legally practice as a licensed social worker in that state. NASW sets professional standards and advocates for the profession nationally. Licensing boards enforce state-level legal requirements. Both matter, but they serve different functions. They’re not the same organization. Licensing exams across states are developed and administered by the Association of Social Work Boards (ASWB).
Does NASW offer continuing education?
Yes. NASW and its state chapters offer continuing education courses, webinars, and conferences that can satisfy CE requirements in many states, depending on state board approval. NASW also runs a CE Approval Program that certifies offerings from outside providers, so courses taken through an employer or third-party trainer may carry NASW CE approval, depending on the provider.
