|Teacher at Westover Hall|
|Appearances||The Titan's Curse|
|“||Despite the danger we were in, I had to bite my tongue to keep from laughing. A teacher named Got Chalk?||”|
–Percy, commenting on Ms. Gottschalk's name, in The Titan's Curse
Percy Jackson, Annabeth Chase, and Thalia Grace run into Ms. Gottschalk and Dr. Thorn while trying to find Grover Underwood at Westover Hall. Ms. Gottschalk stops them and won't let them go any further. Thalia then manipulates the Mist, and makes Ms. Gottschalk think that Percy, Annabeth, and her, are students at Westover Hall. Percy personally finds it funny that a teacher would be named 'Got Chalk' and also says that she was growing a wispy mustache.
