Final answer:
An RBT can have varying numbers of RCs, depending on the certification board or organization they are affiliated with.
Step-by-step explanation:
An RBT, or Registered Behavior Technician, is a professional who provides services to individuals with autism spectrum disorder or other developmental disabilities under the supervision of a Board Certified Behavior Analyst (BCBA).
In terms of RCs, or Reinforcement Competencies, an RBT is required to demonstrate competency in implementing various types of reinforcement procedures to maintain and increase desired behaviors. The number of RCs an RBT can have may vary depending on the specific requirements of the behavior analysis certification board or organization they are affiliated with.
For example, the Behavior Analyst Certification Board (BACB) requires RBTs to demonstrate competency in at least 16 specific RCs, including types of reinforcement such as positive reinforcement, negative reinforcement, and differential reinforcement.
