We received a waiver for two days because of snow, how does i4see know our school did not go 360 half days?

There is a "school data" button on the workbench that allows you to indicate the ending date of school
and the number of half-days in session. You will simply reduce the number of half-days in session and
then i4see will expect fewer that 360 half-days membership for your students who were there all year.
