Explanation
The consultant should evaluate the Education History and Affiliations objects to connect students to other educational institutions. Education History tracks the previous or current education of a Contact, such as the school name, degree, and graduation date. Affiliations track the relationship between a Contact and an Account, such as a student and a school. Relationship is an object that tracks the personal or professional connection between two Contacts, not between a Contact and an Account. Program Plan is an object that defines the requirements for completing an academic program, not the connection to a school. References:
