Which of the following is a requirement to obtain the RBT credential?

Obtaining the Registered Behavior Technician (RBT) credential involves several specific requirements, all of which must be met to qualify. Being at least 18 years old is essential, as this age requirement ensures candidates have reached a minimum level of maturity and legal standing to engage in professional practice. Additionally, a high school diploma or its national equivalent is mandated to ensure that candidates possess a fundamental level of education that provides them with the necessary skills for understanding the principles applied in behavior analysis.

Completing a 40-hour training program is another critical requirement. This training is designed to provide foundational knowledge of applied behavior analysis (ABA) practices and ethics, essential for working under the supervision of a qualified behavior analyst. This comprehensive training helps prospective RBTs develop the skills needed for effective implementation of behavior-analytic techniques.

Since all of these components—age, educational background, and training—are necessary for obtaining the RBT credential, the correct answer encompasses all of the aforementioned requirements. Thus, selecting an option that includes all of these is necessary for a complete understanding of the credentialing process.
