Step-by-step guide to becoming an RBT or Behavior Therapist in California, including requirements, costs, job outlook, and how to start your career at ABA Works.
If you’re looking for a meaningful career working with children, exploring Behavior Therapist (BT) or Registered Behavior Technician (RBT) jobs in California is a great place to start. Across Los Angeles County, especially in South Bay, Lomita, Torrance, Long Beach, and Anaheim, the demand for compassionate, reliable behavior therapists continues to grow.
Whether you’re brand new to ABA or considering your next career move, this guide explains what an RBT is, how many professionals start as BTs, what the requirements look like in California, and why ABA Works is an excellent place to launch your career.
What Is an RBT?
A Registered Behavior Technician (RBT) is a trained paraprofessional who works directly with clients under the supervision of a Board Certified Behavior Analyst (BCBA). RBTs implement treatment plans using Applied Behavior Analysis (ABA) strategies to teach communication, social, academic, and daily living skills while reducing challenging behaviors.
Most professionals do not start as RBTs on day one. Instead, they begin as Behavior Therapists (BTs)—a role that allows you to learn ABA from the ground up while gaining hands-on experience with clients.
Requirements in California
California follows national certification standards set by the Behavior Analyst Certification Board (BACB).
To work as a BT or pursue RBT certification, you generally need:
- To be 18 years or older
- A high school diploma or equivalent
- A clean background check
- Willingness to work directly with children and families
- Availability for consistent weekly schedules
There is no separate state license required to work as a BT or RBT in California, making this an accessible entry point into the ABA field.

How to Become a Behavior Therapist (BT) in California
Many successful RBTs and BCBAs begin their journey as Behavior Therapists. This role is ideal if you’re new to ABA and want paid, hands-on training while learning the field.
Here’s how to set yourself up for success as a BT:
Learn the Basics of ABA Before Applying
You don’t need prior experience, but familiarizing yourself with ABA concepts can help you feel confident during interviews and early training. Learn basic terms such as:
- Reinforcement
- Prompting
- Data collection
- Skill acquisition
- Behavior reduction
Reading introductory ABA articles and reviewing practical examples—such as how reinforcement works in therapy—can give you a strong foundation.

Learn About Autism and Neurodiversity
Behavior Therapists work closely with children diagnosed with autism spectrum disorder and other developmental delays. Watching videos, reading first-person perspectives, and learning about neurodiversity can help you approach the role with empathy and understanding.
Focus on:
- Strength-based perspectives
- Communication differences
- Sensory needs
- Respectful, client-centered care
Prepare for the Interview
ABA interviews often focus on soft skills more than technical knowledge. Employers want to know:
- Can you follow instructions?
- Are you reliable and consistent?
- How do you handle feedback?
- Are you patient and compassionate?
Be prepared to talk about your availability, your interest in working with children, and your willingness to learn.
What Makes a Successful Behavior Therapist?
Being a great BT is about more than liking kids—it’s about professionalism, consistency, and growth.
Maintain a Consistent Schedule
Consistency is critical in ABA therapy. Children rely on predictable routines and familiar therapists. Before applying, make sure you can commit to:
- Regular weekly hours
- Minimal cancellations
- Long-term availability
Develop Professional Work Behaviors
Strong BTs demonstrate:
- Punctuality
- Clear communication
- Professional boundaries
- Openness to feedback
- Accurate data collection
These skills not only improve client outcomes but also prepare you for future roles as an RBT or BCBA.
Be Ready to Learn and Grow
Most ABA companies provide extensive training once you’re hired. As a BT, you’ll learn how to implement programs such as token economy systems, prompting hierarchies, and naturalistic teaching strategies.

- Most BT positions require no upfront certification
- Training is typically paid and provided by the employer
- Many companies support or cover RBT certification costs
