Nice work! Yes, encourage the person to have a conversation with their supervisor in regards to the definition. In talking with their supervisor, the two can agree on what experience can be counted and also agree on how the candidate will track that information.
How else to help:
- Recommend the person review their work responsibilities - the work they do that falls within the definition of DCE can be claimed as DCE hours.
- Suggest that they review the examples of experience that are not considered DCE.
