At 3 months from January virtual sessions: Dr. Minshawi and participants will watch an ADOS administration video conducted by a participant or from training video archives. Dr. Minshawi will lead an interactive discussion on coding and provide participants with feedback on their scoring of the protocol. Format of these sessions will be individualized based on organization and participants’ needs and training goals. (Please note this booster session is part of the main ADOS-2 training beginning in January 2021)
