RBT Exam PrepThe short answer: The RBT (Registered Behavior Technician) is the entry-level credential for behavior technicians, administered by the BACB (Behavior Analyst Certification Board). The exam is 85 multiple-choice questions in 90 minutes, costs $45 plus a $65 BACB application fee, and requires a high school diploma, a 40-hour training, a competency assessment, and a background check.
The RBT credential in plain English
RBT stands for Registered Behavior Technician. RBTs are the frontline professionals who deliver applied behavior analysis (ABA) services directly to clients, most often children with autism and related developmental needs. They work under the supervision of a BCBA (Board Certified Behavior Analyst) or BCaBA, implementing behavior plans, teaching new skills, collecting data, and documenting every session.
Think of it this way: the BCBA designs the treatment plan, and the RBT is the person in the room making it happen, trial by trial, data point by data point. It is hands-on, people-centered work, and the RBT credential is the nationally recognized proof that you know how to do it safely and ethically.
Who administers the exam? Meet the BACB
The RBT exam is administered by the BACB, the Behavior Analyst Certification Board. The BACB is the nonprofit organization that credentials behavior analysts and technicians, sets the ethical standards for the field, and publishes the exam content outline that every RBT candidate studies. In 2025 alone, more than 109,000 people sat for the RBT exam for the first time, which gives you a sense of how large and active this credential has become.
Exam format at a glance
| Detail | What to expect |
|---|---|
| Question count | 85 multiple-choice questions |
| Scored questions | 75 scored, plus 10 unscored pilot questions used for test development |
| Time limit | 90 minutes |
| Exam fee | $45, plus a $65 BACB application fee |
| Where | Pearson VUE testing centers, scheduled after your BACB application is authorized |
| Results | Pass or fail, delivered before you leave the testing center |
Ninety minutes for 85 questions works out to about one minute per question, so pacing matters. The 10 pilot questions do not count toward your score and are not identified, so treat every question as if it counts.
The 6 exam domains

| Behavior reduction | 19% |
| Measurement | 17% |
| Professional conduct and scope of practice | 15% |
| Documentation and reporting | 13% |
