Due to the coronavirus (COVID-19) pandemic, around the middle of March 2020, in-clinic intervention services based in applied behavior analysis provided to children had to be stopped abruptly in India. This qualitative and quantitative case study details how Behavior Momentum India (BMI), an organisation providing ABA-based interventions, transitioned services from in clinic to telehealth while continuing to target each student’s skill acquisition goals in language and communication domains. A cohort of 92 students diagnosed with autism or other learning disabilities participated in this study; 51 therapists, 9 behavior supervisors, and a doctoral-level Board Certified Behavior Analyst collaborated with parents; 78% of the students and 82% of the therapists used smartphones; and only a few used iPads and laptops. Therapists conducted direct sessions and parent-mediated sessions with 82 students. With 10 students, behavior supervisors trained parents to implement interventions with their children. The critical transition decisions, logistics, and ethical challenges were identified using qualitative methods. Despite significantly reduced session durations, all students continued to acquire targeted skills, and 52% of the students acquired more skills in telehealth compared to in clinic. A parent satisfaction survey returned high ratings onour organization’s initiative, and 72% of the parents reported that their familiarity and confidence with the science of applied behavior analysis had increased.
