The answer depends on the requirements of the certifying board. For ABIM, ABA, and ABPath, you may offer learners the opportunity to earn different numbers of credits for the same activity, depending on their engagement with the activity. You may also offer different types of credit, based on the activity, and learners’ engagement with the activity. To determine what specific credit combinations learners may earn, please refer to the relevant board’s program guide.
For ABP, all learners participating in the same activity must currently earn the same number of MOC credits. More information about this requirement can be found here: http://www.accme.org/ask-accme/can-i-report-partial-credit-participants-have-not-earned-maximum-amount-credit-available.
