- "I see you've all bought a complete set of my books. Well done. I thought we'd start today with a little quiz. Nothing to worry about. Just to check how well you've read them, how much you've taken in..."
- —Gilderoy Lockhart[src]
The Defence Against the Dark Arts Second Year Essential Knowledge Test was a "little quiz" given by Professor Gilderoy Lockhart to his second year Defence Against the Dark Arts students to test their reading of his collected works.
- Ron: "Look at these questions. They're all about him."
- Harry: "'What is Gilderoy Lockhart's favorite colour?'"
- Ron: "'What is Gilderoy Lockhart's greatest achievement to date?'"
- Harry: "'When is Gilderoy Lockhart's birthday and what would his ideal gift be?'"
- — Harry and Ron, aghast at the quiz[src]
Rather than testing practical defensive knowledge, the questions on the quiz were all about Gilderoy Lockhart's personal taste, habits, likes and alleged achievements. They covered everything from his favourite colour to his ideal birthday gift. There were a total of fifty-four in all.
Most of the students did poorly on the quiz, showing little knowledge of Lockhart's works, or perhaps simply little interest in them. Hermione Granger, however, earned perfect marks, knowing among other things that Lockhart's favourite colour was lilac and that his secret ambition was to rid the world of evil and market his own line of hair-care potions.

Behind the scenes
- The quiz only appears in the film version of Harry Potter and the Chamber of Secrets in a deleted scene. Despite this, the scene has become widely known because it is played in the extended edition of the film regularly broadcast on ABC Family.
- The first three questions in both the novel and the film are the same, with the fourth question in the film being the one that was the final question in the novel. All other known questions were created for the film.
