I started summer of 2013 and was using Bootstrap 2.3. And I've never seen Clever before, do schools have to sign up to it or how does it work?

So maybe not so cutting edge, but that's ok.

Yes, schools have to sign up to Clever. I'm sure many people develop math, science and english applications, but probably very few develop wood shop applications.
