[Harry Potter] Hogwarts students enter at 11 and stay up to 7 years. Even the most advanced students never learn very powerful magic like the kind dumbledore and Voldemort use. Are there universities for young students who want to further their education?

Its more an apprenticeship based civilization. A student might graduate Hogwarts and be interested in Wandlore, so they would go to Olivander's or some other such place and apply for an apprenticeship.

Either that or there are low level ministry style jobs where you get additional training.
