According to the Edit History section, the Dean Bitterman entry for Prof. Lampwick has been rejected because Professor Lampwick is a college professor, and the trope edit reason (apparently) indicates that this only applies to high school principals.
"The classic Dean Bitterman is found in colleges and universities. Sometimes he turns up in high schools, where he will be the principal of the school."
In addition, there are numerous collegiate-level examples of this trope, such as: Dean Hardscrabble from Monsters University, Dean Yeager from Ghostbusters (1984), Dean Walcott from Patch Adams, and the Trope Namer from the "School of Hard Knockers" segment of "Homer Goes to College" from The Simpsons, et al.
