What does Student ID/Campus ID mean and where do I find that information?

The Student ID can be whatever your school assigns as the Student ID; similarly, Campus ID is provided by the school. For instance, if your institution has multiple campuses but managing your eligible candidates is done by a main office, the main office could ask that each student identify with their respective campus for tracking and/or budgeting purposes. These are optional unique identifiers for your institution that are selected when you first enrolled.
