It'd be hard to top, as far as high school experiences go, finding out and publishing information that got your principal canned. But some student reporters in Pittsburg, KS, did just that.
An ordinary "Meet our new principal"-type assignment turned into an exposé about how the incoming administrator's qualifications were, to say the least, not what they seemed. Educational achievements from questionable institutions, work experiences that didn't add up and so on were brought to light, and the just-hired principal resigned before even officially starting the job.
Now, it seems there may be some legitimate differences of opinion about the resigned principal's actual qualifications. The college in question, which is not accredited now, might have been at the time she took coursework since that was some 20 years or more ago.
But what doesn't seem at issue to me is that the administration and board of the school district are ill-qualified to select a principal of any kind. If high school student journalists can find out stuff like this, you have to wonder why search committees of educational professionals can't. Of course, maybe it's not the case that they couldn't find out the info and check out the record.
Maybe they just didn't bother -- which makes it hard to say what's worse.
