Testing should be standardized and done in a testing center on campus, not proctored by each professor. It has numerous benefits:
- Tests don't have to be done at odd hours, such as super late at night. This was a huge problem when I was a grad student — you couldn't book a lecture hall for midterms except at like 8-11PM, which is dogshit for the students and proctors alike. I can't imagine having to take a super important exam as my long acting stimulant is wearing off late at night, or having to take an extra dose that will keep me up all night just so I can focus on a test. Instead, students can make it to the testing center at whatever hours that work for them and take as long as they need.
- Testing procedures are standardized. However the testing is given (scantrons, blue books, computerized) is the same between all classes and professors and is much more fair. It is also easier for the professor and grad students who teach the class and don't have to spend time worrying about how to fairly administer a test, deal with students problems like forgetting a calculator or blue book, printing out and organizing all the testing materials.
For all the money my university spent on Vice Chancellors for Supporting Israel and whatever, setting up a centralized testing center would have actually improved everyone's lives and the quality of education.
