State License CA RBT-25-481176

The behavior technician is a paraprofessional who practices under the close, ongoing supervision of a behavior analyst or assistant behavior analyst certified by the Behavior Analyst Certification Board and/or credentialed by a state (such as through licensure). The behavior technician is primarily responsible for the implementation of components of behavior-analytic treatment plans developed by the supervisor. That may include collecting data on treatment targets and conducting certain types of behavioral assessments (e.g., stimulus preference assessments). The behavior technician does not design treatment or assessment plans or procedures but provides services as assigned by the supervisor responsible for his or her work.
