It's not uncommon for an administrator to be guarded when it comes to publishing content to the Internet. They're accustomed to running a tight ship with little margin for error. The slightest ease off and you have a ransack of students taking advantage.
Creative Commons (CC) allows administrators the freedom to share any self-created content and let viewers/readers know how they'd like it used. An administrator may create a twenty page manual on how principals should start out a school year, and want others to read it, but not change it in any way. All that's needed is to download an icon/badge and place it on the front or first page of the work and readers will know.
Another administrator may want to share five page observation on motivating faculty at the end of a school year, and want any readers to use it in any manner they choose. Download a different icon/badge and place it on the front or first page and readers will understand their rights to use it.
