If you are planning to continue beyond the advanced certificate in applied behavior analysis and pursue becoming a Board Certified Behavior Analyst you will need to complete fieldwork hours and receive supervision as well as complete an exam through the BACB (Behavior Analyst Certification Board).  The BACB published pass rates for the exam are available here https://www.bacb.com/wp-content/uploads/BCBA-pass-rates-alpha-2017.pdf

Note that pass rates on an exam are only only measure of student success and program value.
