> If you attend a school where students historically perform much better on coursework than on the exam, your predicted score on the exam will be lower. On the other hand, if your school tends to perform better on the exam than in coursework, then your predicted score on the exam will be higher.

This is terrifying. It works for the average student, but distorts the performance for any student who isn't typical or better than their school.

It seems that it would be better to just ignore the testing component of the IB score this year when judging students. Instead they modeled what the students would have gotten on the test, and then judged them based on their modeled performance.

It distorts the performance of a student who underperforms in coursework relative to their peers but overperforms on exams, at a school where students overperform on coursework and underperform on exams. In other words, it punishes the student who does unusually poor on coursework that is already much easier, on average, than typical coursework from other schools.

How likely are such students to succeed at a competitive university? Not very likely at all, I would think.

I don’t agree. It also punishes students with good coursework and who would have performed well on the test, but happen to be in schools which historically perform poorly on IB tests.

If the student outperforms their peers on coursework, then they won't be punished, they will have an estimated score higher than their peers.
