Every minor should require taking a senior-level course
Here’s my possibly elitist university education hot take: I think completing a minor in a discipline should require you to take at least one fourth year course in that discipline.
A minor isn’t a degree, true. But I think claiming to have a minor in a field should mean you’re somewhat literate in a reasonable subset of the basics that any major in that discipline would know and that you have exposure to at least one advanced topic.
If you don’t want to do that, guess what? In most programs, minors are completely optional. Go do a variety of different electives instead.
For example, you can minor in math at some universities without ever being forced to take any course where you write proofs, which I think is absolutely wild.
