Yearly and final credits earned and grade point average (GPA) | StudentAcademicRecord |
Graduation plan and date graduated | StudentSchoolAssociation |
Student transcript interchange should indicate whether it is an official or unofficial submission | <Not in Ed-Fi Core, requires extension> |
Step 5: Validate Extended Reference Types for External References.
