Disclaimer Regarding Licensure Laws
Many states are passing laws that require licensure to practice Applied Behavior Analysis (ABA). Licensing is different from certification. It is possible that even after becoming a Board Certified Behavior Analyst (BCBA) you will not be able to practice in the state where you live without licensure. Some states even have rules regarding which coursework programs will be allowed when applying for licensure in that state.
These laws and regulations are changing rapidly and vary from state to state, so please monitor your state by going to the Association for Professional Behavior Analysts (APBA) and by contacting the licensing board in your state.
