Yong Hao attended the TEACCH advanced topics seminar at Chapel Hill, North Carolina. The course will help professionals further develop their skills as TEACCH practitioner in working with children with Autism Spectrum Disorder and their families. Strategies were also taught to help professionals move beyond the basic implementation of the Structured Teaching concepts and further develop their expertise in topics like program choreography, data collection, program monitoring and consultation in the TEACCH model through lecture, group work and discussion.
