ABA therapy programs also involve therapists, or registered behavior technicians (RBTs). These therapists are trained and supervised by the BCBA. They work directly with children and adults with autism to practice skills and work toward the individual goals written by the BCBA. You may hear them referred to by a few different names: behavioral therapists, line therapists, behavior tech, etc.
