I wrote about what how the International Baccalaureate cancelled its exams, & built a black-box algorithm to assign grades.
The IB won't release the model—& many are asking: did it have a disparate impact on low-income or minority students? https://news.trust.org/item/20200721145229-gm15u/

It's important to underline: nobody really knows exactly how this algorithm works.
Here's a link to how IB has described it: https://www.ibo.org/globalassets/news-assets/coronavirus/may-2020-awarding-further-information-en.pdf

Teachers, parents, & schools all over the world are scrambling to reverse engineer it.
John Chui, a chemistry teacher in Hong Kong thinks he's got it figured out, you can read his analysis if you're into that kind of thing: https://www.jon.hk/jon/essays/ib-m20-grades.html

Another good resource, is this viral blog post by @import_dikshit from last month explaining why using an algorithm in this way might be problematic. http://positivelysemidefinite.com/2020/06/160k-students.html
Also: @tsimonite over at @WIRED had a good piece on the controversy: https://www.wired.com/story/algorithm-set-students-grades-altered-futures/
And, of course, @mathbabedotorg is a must-read, as always: https://www.bloomberg.com/opinion/articles/2020-07-16/this-grading-algorithm-is-failing-students
