- "Well, you'll need to demonstrate the ability to react well to pressure and so forth, perseverance and dedication, because Auror training takes a further three years, not to mention very high skills in practical defence. It will mean a lot more study, even after you've left school..."

Auror training is a three year long program set by the Auror Office to train and evaluate potential Aurors. The program is considered very stringent, and only the best wizards are accepted into it.
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 Defense 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.
After graduating, the Ministry sets a series of character and aptitude tests to further test the worth of potential applicants. The Ministry also runs a background check into the records of new applicants; it was once implied by Dolores Umbridge that wizards with a criminal record cannot become an Auror.
The course of study
For those who are accepted, Auror training takes three years of further study after Hogwarts. Known subjects include Concealment and Disguise and Stealth and Tracking. Poisons and antidotes are also essential studies for Aurors.
Due to the intensity, few candidates have ever been accepted into the program. In 1996, McGonagall noted that, in 1995, the last acceptance had been in 1992. However, after the Second Wizarding War was over, Minister for Magic Kingsley Shacklebolt temporarily relaxed the entry requirements due to the deaths of many Aurors. In order to resupply their forces immediately, Shacklebolt permitted anyone who participated in the Battle of Hogwarts on the grounds that having fought and survived in such a battle and not changing sides against such odds more than satisfied the character and skill requirements.
