Parent training is one of the most important drivers of progress in autism intervention because parents are with their children far more than therapists are. Dr. Mary Barbera and Leanne Page explain how autism professionals can improve parent training by keeping strategies simple, using clear language, showing empathy, modeling skills, practicing together, and ending each session with a realistic plan. When parents feel supported and empowered instead of overwhelmed, they are more likely to follow through and help their child make meaningful progress across everyday routines.
