Applied behavior analysis
One of the more recent developments in Applied Behavior Analysis is the founding of the Behavior Analysis Certification Board (BACB). The BACB is a non-profit corporation that was started in 1998. The BACB certifies behavior analysts. In order to become a behavior analyst a person must go to a special school and then pass an exam. Once they pass this exam they will be  board certified behavior analysts. The BACB sets standards to make sure board certified behavior analysts (BCBAs) are good at their jobs. The BACB makes sure that the BCBAs are using ethical, legal, and professional practices when they work.
