A Registered Behavior Technician is an American paraprofessional credential awarded by the Behavior Analyst Certification Board, sitting at entry level within the wider field of applied behaviour analysis rather than representing an independent clinical qualification.
What the role involves, and its level of supervision
RBTs deliver behaviour intervention plans, most commonly applied behaviour analysis programmes with autistic children, always under the close supervision of a board certified behaviour analyst who holds ultimate clinical responsibility for the plan being delivered. Training to become an RBT is comparatively brief: a forty-hour course, a competency assessment, and an examination, reflecting the entry-level, closely supervised nature of the role.
An American credential, and a contested approach in the UK
This credential is American, and applied behaviour analysis itself is used considerably less in the UK than in the United States, while also being a genuinely contested approach within the autistic community, where views on its appropriateness and methods differ sharply. Anyone considering this kind of intervention for a child would be well advised to look into that wider debate directly.
