Students are failing AP tests because the College Board can’t handle HEIC images

The irony here is that it is the most privileged students who will suffer this the most. It's the ones with the fanciest phones that will run into this bug. Usually these things go the other way -- usually it's the poorest who have to deal with these kinds of things.

Edit: See the reply below about iPhone SEs using HEIC. A point that I missed.

Don't get so ahead of yourself. Even people in relative poverty, in many cases, have new(er) iPhones, and HEIC is default on my SE, the budget iPhone model from 2016. In high schools you're alienated if you don't have the "blue bubbles"* - although it's stupid, if you're in high school in 2020 you probably need an iPhone, and you can get older models for a relatively small price (my SE was <$100). If anything, the ones with the most privilege will have enough technical training to know to make their phones default to JPEG rather than HEIC.
