If you've heard a lot of titles and acronyms since you started looking for support, you're not alone. Here's a plain-language guide to what a BCBA does and how to tell whether one is the right fit for your child.

What does BCBA stand for?

BCBA stands for Board Certified Behavior Analyst. It's a graduate-level certification in behavior analysis, issued by the Behavior Analyst Certification Board (BACB).

To become a BCBA, a professional completes a master's degree or higher, specific coursework in behavior analysis, supervised fieldwork, and a certification exam. BCBAs keep their certification through continuing education, and they follow the BACB's ethics code.

What does a BCBA actually do?

A BCBA uses the science of behavior to answer two questions: why is this behavior happening, and what will help? In practice, that can include:

  • Observing your child at home, at school, or in the community
  • Collecting and reviewing data to find patterns
  • Conducting assessments, such as a functional behavior assessment (FBA)
  • Building strategies that teach new skills and reduce what's getting in the way
  • Coaching parents and caregivers so strategies fit everyday routines
  • Working with teachers and other providers so everyone is consistent

A good BCBA translates assessment findings into real-life support you understand and can use.

BCBA, BCaBA, and RBT: who does what?

You may hear several behavior-analysis titles. Here's how they usually differ:

Questions to ask when choosing a BCBA

  • How will you include our family's goals and priorities?
  • How do you decide what to work on first?
  • How will you explain progress, and how often?
  • How do you collaborate with my child's school and therapists?
  • How do you respect my child's communication style and preferences?

Is a BCBA right for your family?

If you'd like help understanding your child's behavior, building new skills, or getting your child's team on the same page, a conversation is a good place to start.
