It is, perhaps most notably, used by teachers at wizarding educational institutions such as Hogwarts School of Witchcraft and Wizardry, Durmstrang Institute and Beauxbatons Academy of Magic. It is considered rude by some for students to not address a member of a teaching staff on their school as professor, Madam or Sir, as is the case with Professor Snape. Harry Potter often chose to omit this title when speaking of Snape to others, leading them to chastise him. However, the most notable exception to this is Rubeus Hagrid, who is usually referred to by his surname. The term Sir or Madam (depending on the gender) is an alternative title to use instead of Professor, on the speaker's preference. While talking to their colleagues, they usually use their first name. Professor Snape, however, preferred to use others' surnames. For example, he called Remus Lupin, Lupin, and Gilderoy Lockhart, Professor Lockhart in the Duelling Club in 1992. The exception to this would be Professor McGonagall, whom Professor Snape called Minerva.
Powers and rights
Professors have the power to award and dock points (to determine the winner of the house cup competition) give detention and write notes for certain areas and activities that are usually off limits. Examples is how Hogwarts Professors can grant premission to such locations as the Restricted Section in the Hogwarts Library or permission to practise on the Quidditch pitch. Hogwarts Professors can also award and dock points to the four different houses on the school to partake in determining the winner of the house cup competition.
Life outside of classes
Many Hogwarts professors reside at the school during both terms of the school year, though this is not always the case. During the 1980s, Minerva McGonagall owned a cottage in nearby Hogsmeade with her husband, later moving out after his death. It is also possible that those with spouses and/or children can return to a home that is further away from the school in their free time. They likely do this by means of Apparition, the Floo Network, or a Portkey.
Those who remain at the school throughout the night seem to have private quarters, similar to apartments/flats, that are near or attached to their offices. A Head of House may have private quarters near their House's common room. On at least one occasion, Professor McGonagall could hear the noise of a party in the Gryffindor common room from wherever she was sleeping.
Professors typically eat meals with the students in the Great Hall, though this is not required. Sybill Trelawney often preferred to eat alone in her classroom. When Harry Potter attended his first Divination class with her in 1993, she mentioned that some of the students might not have seen her before.
Each Professor most likely has a "free" period during the school weeks, as Harry Potter's third year Defence Against the Dark Arts class once saw Professor Snape in the staffroom. He was also available to serve as a substitute teacher when Remus Lupin was, unbeknownst to the same group of students, ill from the effects of a werewolf transformation.
During the second term of each year, a Professor who is a Head of House holds career counseling meetings with each of their fifth year students, advising them on what N.E.W.T.-level classes they should take in preparation for their desired careers.
When a weekend Apparition Course take place at the school, a Head of House attends and helps to oversee the participating students from their House.
It is presumed that wizards and witches do not need any form of specific education, other than having received their final examination in their own subject and showed particular skill and talent. To become teachers at Hogwarts, it is assumed that the wizard or witch in question usually have passed both their O.W.L.s and N.E.W.T.s, to gain the title of Professor. However, it have happened that someone who did not complete their O.W.L. examinations was able to become a Professor, as long as he or she had been chosen by the Headmaster/Headmistress of the school in question, or if they had been appointed by the Ministry of Magic. This was the case with the Care of Magical Creatures Professor from 1993-1997, Rubeus Hagrid. He was expelled from Hogwarts before being able to complete any 'important' exams, however Hagrid was considered more than qualified on the subject matter. Another example was Firenze, who, as a Centaur, had not previously attended Hogwarts.
