when they are graded solely on test scores there is 100% incentive to rig the scores
Obviously the incentive is present (here at least), but why do you suppose the shirking action is more prevalent when the teacher has fewer students? Shouldn't one expect it to be the exact opposite?

not really. Too many people and scores for the teacher to edit. Remember these teachers arent rocket scientists. The more people you have, the harder it is to get a realistic distribution of grades through shirking. Moreover, it drastically increases the likelihood you'll get one extremely bright student who will get pissed and blab that you're giving the morons better grades with no work.
