I do not think you will ever find one. There are schools out there but not specifically about mining, they teach about blockchain. Your best school is forums like this one, or youtube videos. Maybe you can follow also ask some known crypto mining gurus (look for @notsofast on twitter).
As a side note, if you ever familiarized yourself with mining, I suggest you start with something like Veil. pretty much undervalued right now but has all the potential to reach the levels of Monero.
