The COVID-19 pandemic necessitated a rapid transition to virtual service delivery and supervision. This preliminary study examined acceptability and feasibility of virtual supervision for 94 BCBA/BCaBA trainees during COVID-19, including variables that affected perceived satisfaction, effectiveness, and supervision preference for this sample. Results indicate a decrease in accrual of direct client hours during the pandemic, with a third of participants reporting a decrease in individual supervision. In general, participants were satisfied with virtual individual and group supervision as indicated by high satisfaction domain scores and individual item means, with minimal overall change in satisfaction. Participants indicated preference for in-person or hybrid supervision and considered in-person most effective. In general, participants reported that virtual supervision was feasible and supervisors used best-practice strategies. We discuss variables that affected satisfaction (e.g., length of supervisory relationship), preference (e.g., age, services provided), and perceived effectiveness (e.g., time supervisor was a BCBA). We provide practical implications and recommendations for virtual supervision.
