I think the idea to go paperless for the testing would need to be practiced by our students. Then we go back to an earlier forum question about computer labs, because lets face it... 5th grade has the laptops but we don't have many options for practice with our other grades. At Elvira we don't have a lab (yet) and in the library only 13 desktops and 8 of those are currently not working. We also have two portable laptop carts and those are so slow, most teachers don't bother checking them out.
If we did have more available computers, what about programs like Study Island? They use that at my daughter's school for test prep and it's an on-line program that your site purchases.
