While there is widespread dissatisfaction with the Common Core / standardized tests like PARCC or HSPA in the US, what has gone seriously awry is what is going on in India regarding the Bihar School Examination Test.
I remember, it was burned into my retina, during a high school Geometry test the girl next to me had a cheat sheet under the top of her stockings (no panty hose in those days). When I told her how distracting that is for someone else, she claimed that a male teacher would never search there for crib sheets. Now people climb sides of buildings to get the answers to test takers.
