Abstract: Is there only one Applied Behavior Analysis around the world? Challenges for certification- the brazilian experience in debate. BACB has been certifying behavior analysts all over the world, bringing up quality to professionals working in Service Delivery domain, as well as criteria to define what is a behavior analyst and minimum knowledge necessary to be an applied behavior analyst. Nevertheless, there are crucial differences among academic cultures in different countries in formation of behavior analysts, depending on undergraduate and graduate laws of each one. Brazil has been considered one of the largest group of Behavior Analysis (BA) outside USA and has been receiving awards for its longstanding achievements in Experimental Analysis of Behavior. The graduate bylaws, as well as rules and evaluation systems in BA at graduate level are worldwide based and rigorous. Undergraduate laws and systems of evaluation, on the other hand, are weaker, with multiple differences inside the big country of Brazil. Because if this, it is not possible to homogenize systems of certification in BA in Brazil. Considering this context, a group of brazilian researchers and clinicians proposed a national certification system for behavior analysts and a discussion with BACB representatives is proposed here in order to keep the unit of the field, as well as to keep opened possibilities of new initiatives, due to cultural differences. |
