Allow teachers to manually input grades on tests.

Students who take tests on paper for any reason show up as N/A on data. These are students who have accommodations for print assignments, or Spanish-speakers using printed out versions of the test in Spanish. They are not included in my data and are a really important data point at my school. I would like to be able to go in and add their score and correct/incorrect answers for them so they aren't just lost to the data machine.
