Curiously BEA has two methods to achieve their certifications. Attend some of their traning programs. Here marking your attendance(?) leads to certification. Unless you are sponsored by your employer, you are unlikely to take this route.
The second method is the 'traditional' method i.e. exam through Prometric with a certain passing score.
