The purpose of this study was to examine the psychometric properties of the Identify as a Professional Social Worker Subscale, which assessed the Council on Social Work Education--prescribed competency "identify as a professional social worker and conduct oneself accordingly." The results of confirmatory factory analysis indicated that the items on the measure assessed the underlying latent construct of identification as a professional social worker. The item response theory analysis indicated that the measure could be shortened to a four-item measure, and the item "demonstrate professional demeanor in behavior, appearance, and communication" was the highest discriminating item, whereas "advocate for client access to the services of social work" was the lowest discriminating item. Implications for research, measurement development, and the 2015 Educational Policy and Accreditation Standards are discussed.
