I have a friend who took the test in Iowa and he said another person told him that the reason the results have not been mailed yet is because there was possible "exam subversion" at the Iowa State test site and that they are going through every test with a fine tooth comb.
Now this could be purely rumor and speculation from someone who is getting tired of waiting for their results. I do know that Iowa uses EES. Can anyone confirm or deny this rumor?
