I have been thinking of doing it (UK, smallish town) as I have some experience of training, like doing it, and there is not a lot of competition locally (a lot of publicly funded stuff for adults other than university has disappeared). No idea how to get started though.
I've done short YouTube video versions of conference presentations but never a full course. And I've never really promoted much. It doesn't really take a lot of gear (though it does take some). I'd probably start with doing some YouTube videos and branching out to Udemy or whatever if it clicks.
its a reasonable trade off for me, as a side gig
> At least in the US though, community college or some sort of continuing education isn't going to be a very good gig financially.
Nor here. They also want teaching qualifications. I would rather run something of my own. The problem is how to set it up and advertise.
If you broaden your definition of self-paid adult education, you'll probably find ballroom dance classes, yoga classes, MMA classes, sculpture classes, and things like that.
Perhaps looking at some of them could give you an idea of the economics. Assuming your class wouldn't compete with theirs, they might be happy to tell you how it's going for them :)
