One of the things that I’ve done in snagging cheaters involves careful inventory control of my tests, and subtle variations in the test cases. I know the order and period of each test taker, and when each test goes out. I also vary the cases very subtly from version to version, and embed hidden greek lettes in the versions them selves.

Yeah, I do that kind of thing with tests as well. Multiple versions of a test, and I’ll write a “serial number” in pen on the upper left hand corner of each copy. If the classroom is big enough, I’ll space everybody out so that they are sitting in columns, with at least one seat between any two people. And two people sitting side by side will have different copies of the test. Mostly the same content, but different enough that stealing glances and copying what they see will net them lots of wrong answers. Multiple choice answers won’t be the same on side-by-side tests.
But even more amusing have been the times a person has clearly copied a free response answer from his neighbor’s paper – it will often involve a function name, which is a different word on the different copies. For example, one test uses “Compute”, and the next has “Calculate”. I’ve seen a person write “Compute” in their answer when they have the test with the “Calculate” function name – and the kicker is that the name “Compute” appears nowhere on their test. So they have no viable explanation of where on Earth it came from. Well, save one.
The problem I had with the stolen test (which I linked earlier) incident was frustrating, because it took place in a circumstance that I was not allowed to control. Namely, this was a student registered with the Disability office, and when I get one of those letters at the start of a term:
- I’m required by university policy to accept whatever arrangements the Disability Office deems necessary.
- I can’t ask what the disability is (although the student is free to volunteer info if they wish).
- If the arrangement is for the student to take their tests AT the Disability office to allow more time, I have to allow them to arrange for this.
So what this means is that I have to hand over a test to THEM to administer – it’s not something that I can personally proctor. And this particular student (which I found out after all the proverbial fecal matter hit the proverbial fan) was using the Disability Center – or rather ABUSING it – to pull her little scams. Couple that with the fact that their procedures were extremely lax at the time, and it was not a good situation.
And in the stolen test case, what was brought before the Honor Court as evidence was:
- I numbered all the copies of the tests I made
- The ONLY copy of the test that was not in my possession was the one that was stolen from the classroom on the final exam day.
- The test I dropped off at the disability office for HER to take (several days later) was a totally different test – a makeup test.
- The test returned to me in the envelope by the Disability Office was a copy of the test I had given to the regular class. (Remember, the ONLY copy not in my personal possession was the stolen one).
- On the copy returned to me, I could see where the staple marks had been on the front page – two little black dots (not holes) – which didn’t line up exactly with the current staple. (Clearly a photocopy of the original with my pen-inked serial number whited out).
The Honor Court apparently chose to disregard all this – claiming they found her story credible because there was no direct link between her and the person who did the test stealing (some guy she got to pretend to be in the class and run out with a test).
Unfortunately, the reason he got out with a test in the first place was that I can’t guard every door, and while I had my TAs there with explicit instructions for proctoring, they still allowed themselves to be snowed by this guy, who claimed he’d handed in the test to me already (I told the TAs I would NOT accept ANY tests – they were to be handed in to the TA at the back door on the way out).
Even with the Honor Court not finding her guilty of the stolen test – my position was that I did not have a valid final exam for her, because she had not actually completed the one I dropped off at the Disability Center for her. The Dean refused to make her come take another test, so that we’d have a valid final.
I refused to sign my name to any grade change form with the presumed A on it (and so did my department chairs). I assume the Dean put the grade through.
Since then, the Disability center has made their procedures more specific and more well-defined. And they have cameras monitoring the test-taking room in their new facility. I assume that much of this was because of this particular incident.
