it returns an error if i don't have 2 weeks of data. I found a way around this by doing this
=IFERROR(AVERAGE(OFFSET('1'!E4,COUNTA('1'!D;D)-29,):OFFSET('1'!E4,COUNTA('1'!D;D),)),IFERROR(...-28...-27...
Im Sure there is a better way to do this any help would be appreciated.
I know that its not supposed to be D;D But when i put the : this showed up D:D so i changed it

If you included dates for the grades, you could use an averageif statement
+averageif(A:A, "="& (A15-13), B:B)
where A:A are the dates of the test scores and B:B are the results
A15 would be the last day of the two week period.
Maybe this wont fit in to your template.
