**Short answer:** An RBT (Registered Behavior Technician) is a paraprofessional certified by the Behavior Analyst Certification Board (BACB) who delivers applied behavior analysis (ABA) services directly to clients. RBTs follow treatment plans written by a BCBA or BCaBA, collect data, and must receive ongoing supervision. They don't design treatment or practice independently.

**Key takeaways**
- An RBT **delivers ABA services** directly to clients.
- RBTs follow plans written by a **BCBA or BCaBA** and **don't practice independently**.
- The credential needs **age 18+**, a **high school education**, **40 hours of training**, a **competency assessment** and an **exam**.
- RBTs need **supervision for at least 5%** of their service hours each month.

## What does an RBT do?

RBTs are the people who spend the most time with clients. A typical day might include:[3]

- Running teaching programs from the client's treatment plan
- Using reinforcement, prompting and naturalistic teaching
- Collecting and graphing data during sessions
- Helping with preference and skill assessments
- Writing session notes and reporting changes to the supervisor
- Building rapport and watching for the client's assent

RBTs usually work in clients' homes, clinics, schools or community settings.

## Who supervises an RBT?

A qualified supervisor, usually a BCBA or BCaBA. The BACB requires RBTs to be supervised for at least **5% of the hours** they spend providing behavior-analytic services each calendar month, including **two face-to-face contacts**, at least one of which is individual.[2]

**RBT vs. BCBA in one line.** The BCBA assesses, designs the plan and supervises. The RBT carries out the plan, collects data and reports back. See

## How do RBTs keep their certification?

Starting in 2026, RBTs move to a **2-year** recertification cycle with **12 professional development units (PDUs)** per cycle, earned through in-service training, ACE provider events or university coursework.[2] See [What changed for RBTs in 2026?](https://theautismkit.com/guides/rbt-2026-requirements)

**Ask about growth.** When interviewing, ask how the organization supports RBTs who want to become BCBAs: tuition help, fieldwork
  supervision and flexible schedules make a big difference.

No. RBT applicants need a high school-level education or equivalent, and must be at least 18. Many RBTs are in college or planning graduate school.

### Can an RBT work without a supervisor?

No. RBTs must be supervised by a qualified supervisor for at least 5% of their service hours each month. Without a supervisor, an RBT can't practice.
