It would obviously need to be catered to each major. And it won’t exactly align with any one school’s curriculum, but it’d be great to see actual stats of who knows what after graduation across thousands of students.
Thinking about this a bit more, this is something the government could definitely do. Have schools submit students to these tests as a condition of receiving federal funding. Any student that graduates that doesn’t take the test counts as a zero for the schools numerator but still a one for the denominator.
