i know people who have cheated on SAT's, college midterms and finals and heck I'm one of them. There has to be a certain level of desperation involved to cheat on a high-stakes test, because typically if it's high-stakes if you get caught you're completely screwed. I think everyone has been caught once
No, I do not know of anyone personally who has cheated or cheats on High-Stakes Tests. In saying that, I have heard second hand accounts or "through the grapevine" stories of this occurring. I have not known anyone that has admitted to, or has been caught, cheating on any test that has high stakes.
