Add/Update:
This option will append any new data to the existing data for the term. New profiles are created for any new students or teachers, and existing profiles will be updated. Profiles not included in the roster will be unaltered. No existing classes, profiles, or programs will be removed.
This option is selected by default, and is appropriate for most circumstances.
Overwrite:
This option is only available if there are already students or teachers rostered to the selected term. With this roster option, all existing term data for any student or instructor in any school included in the roster will be replaced. Students and instructors omitted from the roster will become unrostered for the term. See
What does "Overwrite" do when importing rosters? for more details.
Since this option removes existing term data, you should not use it unless you have a specific need to remove data. Some examples of when you might use this option are below:
- You have a highly mobile student population
- You accidentally imported a roster for the wrong term
- You initially imported data before class assignments were finalized
- There was a major error on the previous roster, such as rostering all students to the wrong grade
