A Registered Behavior Technician (RBT) is a professional who works in the field of psychology and behavior therapy. Their primary role is to provide direct support to individuals in need of behavioral therapy, under the supervision of a Board Certified Behavior Analyst (BCBA).

RBTs assist in implementing treatment plans designed by BCBA to help individuals develop appropriate social, emotional, and behavioral skills. This may include working with individuals with autism spectrum disorders, developmental disabilities, or other behavior-related challenges.

RBTs must complete a training program and pass an exam to obtain their certification. They are also required to adhere to an ethical code and maintain their certification through ongoing education and supervision from a BCBA.

In summary, a Registered Behavior Technician is a trained professional who helps individuals with special needs develop appropriate behavioral skills under the supervision of a certified behavior analyst.
