> make large percentages of a student's grade come from in person tests
One possible solution is to remove technology but then you’ll need to detect smart glasses and other hidden devices. Another possible solution is to expect the use of AI and design assessments that are so hard that you have to work in tandem with AI otherwise you can’t get a good grade.
You cannot make it impossible to cheat, you can only make it hard. For example with your suggestion the student could use the old standby of paying experts for help.
The nice thing about monitored testing is that it makes cheating hard, and if you catch somebody there's usually incontrovertible proof.
