You are looking at two different areas here.
1. The requirement for an annual CRM refresher (ground school, which needs to be conducted by a CRMI(ground).
2. Your line check, which should include a CRM assessment, completed by a Line training captain, who should also be a CRMI(Line).
Its all in the CAP 737, and the CRMI (of whichever variety) should be aware of it.
