Academic Role And Professional Identity Development In Counselor Education, Seth Scott
Academic Role And Professional Identity Development In Counselor Education, Seth Scott
Walden Dissertations and Doctoral Studies
Professional identity development occurs during graduate training through mentoring, modeling, and academic training by counselor educators. If counselor educators are to transmit this professional identity, they must possess a robust professional identity themselves. Professional identity development theory suggests that the strength of this professional identity may be threatened by a lack of belonging in academia for nontenured or contingent faculty. A correlational research design using a purposeful convenience sample was used to examine the relationship between academic role, employment status, years of experience, and professional identity among counselor educators. The participants (n=50) were counselor educators who subscribe to the CESNET-Listserv. …
