From Wikiversity

A "Wikiversity school" is a very large organizational unit. The goal is to use this category for relatively few Wikiversity schools that are the "major schools" similar to the list that was developed by the Wikiversity community at Wikibooks. The "topic" namespace should be used for smaller organizational units such as departments. See: Wikiversity:Namespaces and Wikiversity:Naming conventions for infomation on the use of "School:" and "Topic:" namespace pages as special purpose portals in Wikiversity. Schools in this category can be listed at Wikiversity:Browse. See also: Wikiversity:Schools.
