That does happen and it is considered intentional, but, no I meant the staff themselves damaging them. Drawing on them (the screen in particular, which often doesn't come off cleanly), popping the keys off and on until they break, flexing parts of the case (hinge covers) until it breaks, getting angry and hitting the computer and breaking something. Anything you would expect a kid to do we've seen teachers admit to doing themselves. Kids do that stuff too, but they also do stuff like break headphones off in the jack, punch a hole in the screen with a pen, gouge the screen with scissors or a hobby knife, smash them on the ground, stand on them, sit on them, etc.
