I disagree to add QABA. The BCBA helps make sure that BCBA's, BCaBA's, and RBT's are practicing within their scope and that they are providing ethical services to their clients. ABA has a bad rap from the past and with the help of the BACB it is helping change the way people look at ABA therapy. We need to continue to on providing ethical practices of ABA with clear guidelines and qualifications for everyone that is practicing ABA.
