The short answer

All three are BACB credentials. An RBT (high school education) delivers services under supervision. A BCaBA (bachelor's degree) can do some assessment and program work and supervise RBTs, but must be supervised by a BCBA. A BCBA (master's degree or higher) practices independently, designs treatment and supervises the team.

Key takeaways
  • RBT: high school education, delivers services, always supervised.
  • BCaBA: bachelor's degree, supports assessment and programming, supervised by a BCBA.
  • BCBA: master's degree, practices independently and supervises.
  • Many people move RBT → BCBA, sometimes via BCaBA.

What does each role do on a team?

  • The RBT runs teaching sessions, collects data and reports to the supervisor. See What is an RBT?
  • The BCaBA can help with assessments, write programs, analyze data and supervise RBTs, under BCBA supervision.
  • The BCBA leads assessment and treatment design, trains caregivers, supervises the team and makes clinical decisions. See What is a BCBA?

Which path should I choose?

  • Want to start working soon? RBT is the fastest way in.
  • Have a bachelor's and want more responsibility? Consider BCaBA, but check local demand.
  • Want to lead clinical work? Plan for BCBA.

Common questions

It can be if you have a bachelor's degree and want more responsibility before or instead of graduate school. Check whether your state and local payers recognize BCaBAs, since demand varies.
