Drawn on the theoretical principles of sociocultural theory and constructivism, the aim of this multiple case study was to explore and understand the experiences of interpreting students, interpreter graduates, and pre-certified working interpreters after receiving ASL mentoring for at least 3 months to a year and to learn about the roles and impacts that ASL mentoring had on those groups of people as ASL mentees. Graduated from their respective 4-year universities for a bachelor's degree related to the field of interpreting, participants included one interpreting student and one interpreter graduate, both of whom were from southern California, and one pre-certified working interpreter who was from Oregon. To triangulate (Maxwell, 2013) data across participants, methods included as follows: one-time virtual Zoom meetings, initial email interviews, follow-up emails, and artifacts. Data processing and analysis included a first cycle of process coding, a second cycle of pattern coding, and an in-vivo coding.
