ABSTRACT The Innovative Mentoring and Professional Advancement through Cultural Training (IMPACT) program is a multi-dimensional, inter-institutional, collaborative mentoring program for students who identify with historically underrepresented groups and who are interested in communication sciences and disorders (CSD). This program is a collaboration between Case Western Reserve University, a top US research university, and Hampton University, a top-ranked Historically Black College and University (HBCU). Currently, the program supports 21 undergraduate students in CSD and clinical speech-language pathology graduate students. This supplement has two aims. The first is to further enhance the students’ self-sufficiency and prospects for success by adding group and individual coaching sessions that foster the development of robust professional identities and life skills (including time management, organization, and stress management). This supplement will support a carefully structured approach to cultivating these identities and skills in our current target population. The second aim is to enhance the knowledge, self-efficacy, and sense of belonging of underrepresented Doctor of Audiology (AuD) students. Because AuD programs tend to be small (an average of 10 students), underrepresented AuD students often find themselves in cohorts where none of their peers share their background. Through this supplement, AuD students will have access to the entire IMPACT curriculum and will participate in clinical case discussions, grand rounds, and journal groups, activities that will help build a sense of community and social belonging. They will also have the opportunity to practice and enrich their academic skills. Both coaching and mentoring will be delivered by program faculty who identify with historically underrepresented groups. The supplement will enable us to assess the benefits of coaching paired with our robust mentoring program for the students we currently serve as well as the effectiveness of our expanded model for an online cohort of AuD students.
