(a) Social workers should make clear distinctions between statements made and actions engaged in as a private individual and as a representative of the social work profession, a professional social work organization, or of the social worker's employing agency.
(b) Social workers who speak on behalf of professional social work organizations should accurately represent the official and authorized positions of the organization.
(c) Social workers should ensure that their representations to clients, agencies, and the public of professional qualifications, credentials, education, competence, affiliations, services provided, or results to be achieved are accurate. Social workers should claim only those relevant professional credentials they actually possess and take steps to correct any inaccuracies or misrepresentations of their credentials by others.
Some of this reads more like human resources than social work (though they often coexist, now that you mention it). Details from an overlong contract. But social media brings some of this to more-relevant-than-it-used-to-be status. Tweeting about your job? Make it clear whether you're tweeting on behalf of your employer or not. "Opinions are my own," is a simple way to clear that up.
But what does that have to do with the social work licensing exam? Not so much, unless a simple question about Twitter disclaimers somehow found its way onto the test. More relevant is the material in (c). A question might reach into some grey area about how a social worker should represent themselves. "A social worker has passed the licensing exam but not yet received his license from the state board. What should the social worker put on his new business cards?" That sort of thing. Remember that you can rarely go wrong with a by-the-book, dotted i's, crossed t's answer. Meaning it may be premature for this imaginary social worker to call himself licensed. Don't misrepresent!
