Probably helps that "We prepared complete documentation of everything we did, including recommendations to remediate the vulnerabilities we discovered. We went a comprehensive 26-page penetration test report to the D214 tech team and worked with them to help secure their network."
That hasn't helped in the past. Frankly I think they were naive to reveal themselves no matter what the authorities said. It hasn't gone nearly as well for other people.
The advice given to me in high school (I was working on tech projects after school for several teachers and groups) was to not even try or explore poking around the IT networks it no matter how good my intentions were. All it takes is one grumpy school administrator to feel undermined or to misunderstand your report and you could be expelled.
When you're in a position like a student, you're still working your way up and building credibility. No need to risk it all for an IT group that doesn't want your security advice and didn't ask for your help.
