Just choose each class for which you want to generate attendance records for from the drop down list. Enter the date of the class (you may use the pop up calendar to make this quicker, or just type in the date) then click the button to create attendance records. Repeat the process for all classes then click the close button. You will then want to browse attendance records and begin updating records.
