Absence Verification code can be mass-set for Section-Based attendance. For example, if an entire group of students goes on a Field Trip, this feature can be used to streamline updating their records. Here are the steps you can use.
Step 1: Navigate to the Absence Verification by Period screen. On the upper-right, you'll see an Actions button. Click that to select the "Mass Set Attendance Code - by Section".
Step 2: Once there, you can select the attendance code, date and sections you want to set.
Step 3: Preview the list of students and if all looks good click on "Confirm Mass Set Attendance".
Note that students that already have an attendance code set will not be overwritten.
