no score effecting data

[JulieBye]

When viewing a report, are students with "no score" counted in the total number?  For example when viewing the percentage of students showing mastery, are the no score students counted as not showing mastery?  

If so, this becomes an issue for us when looking at school wide data because we have some classes where the test is in the tracker and those kids are showing as a no score, BUT those kids are not supposed to take the test as they have a different test to take.
