Dimmsdale High School is an educational building in Dimmsdale that teaches grades 9 through 12.
The structure somewhat resembles Dimmsdale Elementary School, but it is beige colored instead of white and purple, and the tower at the front looks like a castle tower. The school has an auditorium for school dances, as well as a football and soccer field. A sign outside the school reads "Home of the Dodo's" which is probably the name of their football team.
In its original Oh Yeah! Cartoons appearance, the high school was colored red and had an arching roof with glass panel windows.
Dimmsdale High School first appeared in "Where's the Wand?", hosting a costume dance. Vicky unknowingly used Wanda's wandto cause trouble during the party, although she only really succeeded in ruining her own costume.
The high school was the central setting of "A Bad Case Of Diary-Uh!", when Timmy Turner went there to spy on Vicky and use things from her diary against her, mainly her crush on a foreign exchange student named Winston Dunsworth. Vicky is also seen trying out to be a cheerleader in an outdoor area near the school with stands, although her efforts are sabotaged by Timmy. Timmy later learns the consquence of ruining Vicky's chances with Winston(which was having a group of more eviler people than Vicky to babysit him) and tries to fix things by using Winston's fear of the color pink to get Vicky to save him and so that he would fall in love with her. Timmy is beaten to a pulp during this as Vicky found out that Timmy read her diary to find out about this. Despite all this Winston still will not go with Vicky as she still didn't accomplish at becoming a cheerleader. Although Timmy and Wanda got beaten up, they told a group of men, it was time for "the hunt" which were they were going to use get back at Cosmo.
