- "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 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.
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.
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.
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; Dolores Umbridge once implied 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. It is also highly likely that they learn to detect and identify traces on places that has known magic, especially the traces of Dark Magic. They are presumably also taught about magical jurisprudence to make sure they apprehend criminals on legally valid grounds.
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.
- As American wizards do not attend Hogwarts, it is unknown what requirements they have to become Aurors.
