n0, you are right about learning being different from professions and a (popular) test may lead to only people passing (a trivial) test being accepted. Still, historically, people will have semicha exams, tests when hired as Rabbis … We use a lot of modern tools – search divrei torah by keywords, drive to a shiur, buy books with translation, etc. One of those tools is ability to expand testing from one great teacher to be replicated to many. As an aside, I was skeptical about multitudes of multiple choice questions my kids have in online schools, but I now see the strength of ability to routinely test and get feedback on your performance without hiring a teacher to sit near you and grade your work. As I see, some people here started asking possible questions. Maybe we can collect a bunch of diverse questions to come up with a test and then can go around and report how people/kids performed.
