When looking for a behavioral consultant, it is really important that you look at the qualifications of that person, particularly at the supervision level.
The California Association of Behavior Analysis provides a useful article about how to find a behavioral consultant: http://www.calaba.org/AAMR-BehConsultantsFlyer.pdf.
The Behavior Analyst Certification Board is the first organization to provide national certification credentials for behavioral consultants. When you see BCBA or BCABA after someone’s name, this assures you that the person has completed the required number of hours, supervision, education, and passing the national board exam. If you would like to know if someone has these credentials, you can look them up on the BACB site! This is a great place to start looking for someone to help you with a home program that lives in your state.
