Question - I'm looking at a percentage attendance between report and one student is showing zeros all through when looking at a date range a couple of years ago
Answer - This could be due to the student having two different records of attendance at the school, i.e the student could have been at the school, left and then returned at a later date. To check this you can go to the student profile Ancillary Tab and it should show you the student's previous time at the school.
If you want to run the Percentage Attendance Between report for the previous time at the school, you will need to change their entry date to the first date the student started at the school. this can be found in the school history area of the Ancillary tab. once you have your report, remember to change entry date back to the new entry date.
