Quick answer
A Registered Behavior Technician (RBT) delivers behavior-analytic services directly to students under supervision; a Board Certified Behavior Analyst (BCBA) assesses behavior, designs intervention plans, and supervises RBTs. RBT certification requires a high school diploma, 40 hours of training, a competency assessment, and an exam. BCBA certification requires a master's degree, specific coursework, supervised fieldwork, and an exam.
Key takeaways
- RBTs deliver services; BCBAs assess, design plans, and supervise.
- RBT is an accessible entry point — no college degree required.
- BCBA requires a master's, coursework, supervised fieldwork, and an exam.
- Many BCBAs started as RBTs or paraprofessionals.
Applied behavior analysis (ABA) has become a familiar part of school support for many students, particularly students with autism and students with significant behavioral needs. Two certifications from the Behavior Analyst Certification Board (BACB) show up most often in schools: the RBT and the BCBA.
The two roles side by side
RBT
Direct support, under supervision
Works directly with students, implements teaching and behavior plans, and collects data.
BCBA
Assessment, design, supervision
Conducts assessments, writes behavior plans, trains staff, and supervises RBTs.
What an RBT does in a school
- Provides 1:1 or small-group support following the BCBA's plan
- Runs teaching programs and practices skills with students
- Supports behavior intervention plans consistently across the day
- Records data accurately so the BCBA can make decisions
- Communicates with teachers and classroom staff
What a BCBA does in a school
- Conducts functional behavior assessments (FBAs)
- Writes and revises behavior intervention plans (BIPs) with the IEP team
- Supervises and coaches RBTs, paraprofessionals, and classroom staff
- Analyzes data and adjusts plans
- Consults with teachers, administrators, and families
RBT requirements
- Be at least 18 years old with a high school diploma or equivalent
- Complete 40 hours of approved RBT training
- Pass an initial competency assessment with a qualified supervisor
- Pass a background check
- Pass the RBT certification exam
- Receive ongoing supervision while practicing
BCBA requirements
- A master's degree (or higher) from a qualifying program
- Approved coursework in behavior analysis
- Supervised fieldwork — a substantial number of hours under a qualified supervisor
- Passing the BCBA certification exam
- Ongoing continuing education to maintain certification
- A state license where your state requires one
From RBT to BCBA: a common path
- 1
Start as an RBT or paraprofessional
Get hands-on experience supporting students and learning ABA in practice.
- 2
Enroll in a master's program
Choose one that includes the required behavior-analytic coursework. Many are designed for working professionals.
- 3
Complete supervised fieldwork
Your RBT role can often count toward fieldwork when it includes the right activities and supervision.
- 4
Pass the BCBA exam
Then apply for a state license if your state requires one.
Working in schools vs. clinics
School-based ABA looks different from clinic or home-based ABA. You work on the school calendar, inside classrooms with other staff, and in support of IEP goals. Collaboration with teachers matters as much as technical skill — the best school-based plans are ones the whole classroom team can carry out.
“In schools, a behavior plan only works if everyone in the room can follow it on a busy Tuesday.”
Frequently asked questions
What is the difference between a BCBA and an RBT?
An RBT works directly with students to carry out behavior-analytic plans under supervision. A BCBA conducts assessments, designs those plans, and supervises RBTs. BCBA certification requires a master's degree; RBT certification does not.
Do you need a degree to become an RBT?
No. You need a high school diploma or equivalent, 40 hours of approved training, a competency assessment, a background check, and a passing score on the RBT exam.
Can RBT hours count toward BCBA fieldwork?
Often, yes — when the work includes the activities and supervision the BACB requires. Confirm the current fieldwork rules with the BACB and your supervisor.
