This is what the websites say:
Do I have to take a class to become certified?
No, you may opt out of the training course, and schedule the Level 1 exam at any Apple Final Cut Pro certified training center. To become (level 2) certified, you must take an official Apple Final Cut Pro advanced certified training course in order to quality. Level Two exams can only be taken in conjunction with the Advanced classes taught at the Apple Authorized Training Centers.
How much does the exam cost?
The exam fee is $150 and is non-refundable upon taking the exam. If you do not pass, you may retake the exam after 24 hours. You will be required to pay another $150 per exam attempt.
How difficult are the exams?
The exams are fairly comprehensive, and will test even the seasoned Pro Applications veteran. We recomend taking a corresponding certified training course in order to prepare for it. We cannot guarantee that you will you pass, but we do our best to prepare students for the concepts that are covered on the exam.
There is a list on Apple’s website to where you can find Authorized Training Centers to take the exam.
