6.2.2 c) requires you to "evaluate the effectiveness of the actions taken" (from 6.2.2b).
The question is: "How do you know (when you train on an SOP) that the trainee "got" the message?" A written test may be an indicator, but how many people do you know that are good with tests, but lousy with performance. Remember one of the major changes in 13485 is the change from "qualified" to "competent". A written test probably will not meet the competent requirement.
The answer lies in how you determine that the trainee is competent to perform to the SOP. Probably the best way is to monitor performance. If the supervisor is satisfied that the new performance is acceptable, then you've met 6.2.2 c).
The next logical question would be concerning records of the above. 6.2.2 e) requires you to "maintain appropriate records". We've battled this greatly in the ISO 9K threads, however, my belief is that it is up to you (your customer, or national agency) to determine what type of records are to be kept.
Hope that helps.
Oh, by the way, I just noticed... Welcome to the Cove
