Promoting grades in Planning Center People won't affect the status of groups you have set up by grade level. You can create a new group to reflect the promotion of the group members.
Tip
Rename your current group to reflect the past school year and create a new group to reflect the upcoming school year.
Rename the group in the Settings by adding the date of the prior school year. For example, if your current group is 2nd Grade Parents, add the date of the previous school year to change it to "2nd Grade Parents (2024-2025)".
Create a new group for the upcoming school year, for example, "3rd Grade Parents (2025-2026)".
The fastest way to copy students into the new group is to add multiple people to the group using bulk actions in People.
Archive the group for the prior school year. This will keep the attendance history and reporting intact for that group and will show accurate data of Groups participation according to Grade in People activity feeds.
