Book excerpt: The RBT Book is a comprehensive manual for Registered Behavior Technicians(R) (RBT(R)) and RBT(R) Candidates. It covers all competencies in the RBT(R) Task List, includes concepts, examples, visuals to prepare the RBT(R) Candidate to pass the RBT(R) Exam and master the skills necessary to provide effective and ethical services to ABA clients. The RBT(R) Book is unlike any other; it focuses on both content and exemplars of what it means to be an RBT(R), the use of visuals explaining the material further than any other book, and task analyses on "how-to" do the work of an RBT(R). Each chapter includes summaries and tips to better prepare future RBTs(R). Registered Behavior Technician(R) (RBT(R)) is owned by the Behavior Analyst Certification Board, Inc.(R) (BACB(R)).
