Transfiguration (class)

"Transfiguration is some of the most complex and dangerous magic you will learn at Hogwarts. Anyone messing around in my class will leave and not come back. You have been warned."

- Professor McGonagall introducing Transfiguration to her new students

Transfiguration is a subject taught at Hogwarts School of Witchcraft and Wizardry. It teaches the art of changing of the form and appearance of an object. This type of magic is commonly referred to as "Transfiguration." There are limits to transfiguration, which are governed by Gamp's Law of Elemental Transfiguration. There are also many branches of Transfiguration, including Cross-Species Transfiguration and Human Transfiguration.

Class information
Transfiguration is a required subject for all first year students, with the option of a N.E.W.T. course in the sixth and seventh years. Minerva McGonagall was the Transfiguration Professor from 1956 until 1998, the year in which she became Headmistress of the school. Before her, Albus Dumbledore taught Transfiguration.

It is unknown who became Transfiguration professor after McGonagall became Headmistress of Hogwarts. McGonagall believes Transfiguration to be more elegant and superior to other types of magic.

Like Charm work, Transfiguration is achieved through concentration, precise wand movements, and the proper pronunciation of an incantation. However it is generally more difficult than Charms and requires great effort.

Students practise actual transfigurations during Transfiguration classes. Accidents sometimes result in partial transfigurations. Hermione is one of the best students in Transfiguration; therefore, she is a favourite of Professor McGonagall.
