Providing evidence-based and affirming service to Individuals with complex communication needs (CCN) is the responsibility of all speech-language pathologists, regardless of practice setting or professional season. Clients with complex and varying profiles bring unique strengths and needs to the therapeutic relationship, demanding additional supervision focus for graduate clinicians and clinical fellows beyond what might be provided in more ‘traditional’ practice scenarios. Although the nature of supervision in AAC practice may flex as novice clinicians become more experienced and self-reflective, bringing effective and affirming practices into perspective can and should start as early as pre-service training and continue throughout graduate clinical experiences, post-graduate fellowship, and life-long practice. Ensuring that graduate students and clinical fellows are well-prepared to provide AAC services is essential for promoting the well-being of people with CCN. This training outlines key principles for the effective supervision of graduate students and clinical fellows in the field of speech-language pathology when working with individuals with CCN who communicate with AAC. Borrowing from ASHA supervision guidelines and integrating a lens of reflective practice and reflective supervision, this session will explore the importance of ‘ways of knowing,’ ‘ways of doing,’ and ‘ways of being’ to foster a supervision relationship that encourages career-long evidence-based and reflective practice.
