A Behavior Analyst is a professional who studies and applies the principles of behavior analysis to understand and modify behavior. They often work with individuals who have developmental disorders, such as autism, using techniques based on the science of behavior to improve communication, social skills, and daily living activities. These specialists typically hold a graduate degree in behavior analysis or a related field and are certified by the Behavior Analyst Certification Board (BACB). Their work may involve conducting assessments, developing treatment plans, and training caregivers to implement effective strategies for behavior change.
