Training Security Trolls

Training Security Trolls was the title of a pamphlet that Hermione Granger read while trying to decide which elective courses to take in her Third Year. It described the training one would require to enter the field of security troll training, and the avenues of study they would have to pursue. It was likely published by the same company as Have You Got What It Takes to Train Security Trolls?.
