I am reviewing Ethics and I am not sure if it’s ok for someone to wrote “I passed CFA Level I exam with >90% in all sections” in his resume. Does this violate the standard?
Only if it isn’t true, or if the person implies that that makes them a better analyst than someone who passed with a lower score (or failed).
It won’t violate ethics but it will make you look like a Tool. Just leave it at Passed Level X.
