Read about the original wizarding school in Ursula K. LeGuin's Earthsea Cycle: A Wizard of Earthsea, The Tombs of Atuan, The Farthest Shore, Tehanu, etc. Those are the LeGuin books you'll probably like the most, but I haven't read anything of her's that I didn't enjoy immensely. There's another one with space faring dwarves, elves, and knights that go questing on the backs of flying tigers; Rocannon's World is set in another series of her's, The Hainish cycle. That series looks like science fiction, but feels like high fantasy.
