Term Grade and Attendance Event are two objects that the consultant should use to address the requirements of tracking student absences from class and midyear grades. Term Grade is an object that stores the grades that a student receives for a course offering in a specific term. Attendance Event is an object that stores information about a student's attendance or absence for a course offering or a course connection. Behavior Involvement and Program Enrollment are not objects that can track student absences from class and midyear grades. Reference:
