Explanation
The consultant should use the Document Checklist Item object to track which requirements must be met for a student application. Document Checklist Item records are related to Application records and define the type, status, and source of the required documents. Action Plans are used to track tasks or actions related to an application or enrollment process, not document requirements. Application Material Mapping is used to map application documents to application requirements, not to track them. References:
