Auror training

Auror training is a three year long programme set by the Auror Office that was established by Minister Eldritch Diggory sometime between 1733 and 1747 to train and evaluate potential Aurors. The programme is considered very stringent, and only the best wizards are accepted into it.[1]

Qualifications
To qualify for Auror training, a witch or wizard must first have attained at least five N.E.W.T.s of no less than 'Exceeds Expectations'. Minerva McGonagall once recommended that Defence Against the Dark Arts, Transfiguration, Charms, and Potions would be useful N.E.W.T. level classes for those wishing to pursue a career as an Auror.

Behind the scenes
As Kingsley Shacklebolt successfully managed to modify the memory of a Hogwarts student without causing any damage, it is possible that Aurors are trained in the use of the Memory Charm in case their work forces them to venture out in the Muggle society while tracking down Dark wizards or witches who has gone into hiding and some of the non-magical community observe them using magic, meaning that Aurors might be, at least in part, responsible to enforce the International Statues of Wizarding Secrecy during their work out in the field.
