You can change students' default groups one at a time or all at once.
For individual students, go to Students > Roster > Click the Bar Chart Beside the Desired Student > Click the "Edit" button > click (change default) > select new group > click Set Default.
To mass update students' default groups, go to Students > Roster > Add or Upload Students > Download Student Roster Export. This will open your student roster in a .csv file in Excel.
Next, you will change the group name in the Group column for each student whose default group you'd like to change:
Back in Kickboard, go to Students > Roster > Add or Upload Students > Upload button. Browse for your updated file, leave the options set as Kickboard file format and Update Only. Don't worry, you’ll be able to review these changes before confirming them.
