Check the following:

• Is the School Calendar set up for the new school year? Go to Attendance System > Maintenance – Attendance > Calendar Maintenance. If you do not have a calendar, create one. If you have one, confirm the Start Date is your first day of school.
• Is the enrollment date in the student’s enrollment record within the School Calendar? The enrollment date is usually the same as the first school day in the school calendar. In the case of PreK and Kindergarten, they may start on a later day. If enrolled with a date before the calendar’s first day of school, you will see “error” for enrollment.
