I do not own any of the characters listed - they're all the property of the amazing JK Rowling, except for the odd real person.

Potions — Severus Snape (Under probation)
Severus had an excellent record at Hogwarts as a student, and comes to us highly recommended by Horace Slughorn as a suitable replacement once Horace retires. Thus, Severus has spent this year under the guidance of Horace, learning the curriculum, the art of teaching and the various administrative necessities of the position. His work has been commended, and while his discipline does err on the side of strict, the general results have been exemplary. OWLS and NEWTS in Potions have increased, and the examining staff this year particularly mentioned the care with which students prepared the assigned recipes. It is recommended that his probation be ended and he be confirmed in the position of Potions Teacher and Head of Slythern House at the beginning of the new School Year.
Excerpt from the diary of Severus Snape, August 1982.
… and the worst year in my life. Oh sweet Merlin do I really have to stay here and teach these total dunderheads. Some of them were here when I left — that idiot Larry Dingle couldn't make a simple Sleeping Draught if I held his hands while he chopped! He's determined to be a singer — wants to change his name to Lorcan. I told him he'll be the death of my ears, and for some reason he clapped me on the arm and thanked me! I'd rather teach flobberworms. And Horace made me look after the First Years — I think I'd rather be a leech-herder. Bloody Scabior took a week to stop crying for his mother — after the third-years saw him he won't be so weak again. He can't afford to be. None of us can.
I still can't believe she's gone.
