How many hours of IEBT per week are needed to produce gains?
Most evidence suggests an average of 25-40 hours Intensive Early Behavior Therapy per week is necessary to make major gains. We usually recommend 25-40 hours per week for the first year based on the recommendations of the National Academy of Sciences and the State of New York reviews of best practices in educating young children with autism spectrum disorders, and clinical experience from the various programs working with young children with ASDs. Our experience has been consistent with the research literature in that less than 25 hour per week does not produce optimum gains.
