I can't imagine what field you are in. I was thinking accounting, but the CPA has higher pass rates.
Here is the thing, Pharm D programs solely prepare students to be pharmacists. The pass rate really should be very close to 100% (there will always be illness or emotional stress from a situation in life that keeps the rate from 100%), but schools should not be graduating students who can not pass the NAPLEX, they should be failing them.
Whatever field you are in, I would imagine that your degree would allow you to work in that field in some capacity, even if you didn't pass your certification exam. Many degrees, like accounting, are broad and prepare people to work in several different areas of that field, and people can work in the field without having to pass a certain test. This is not true of pharmacy.
