Community colleges have deans that oversee both students and staff. Typically a student dean takes care of day to day administration of student affairs, while a faculty dean takes care of day to day administration of the faculty. If a community college has, as most do, a large amount of evening classes, there might be a second faculty dean to handle night faculty, and a second student dean to handle the student affairs of night students.
Each community college has a governing board that makes financial decisions and oversees the running of the community college. The board is typically made up of several people who meet once a month to see college issues and vote on them. Typically the board members are voted into position or are appointed into position by the community college itself.
Community colleges are made up of all types and ages of students. Many students are nontraditional, so they might have tried other types of colleges before and have not gotten anywhere. Most community colleges want all of their students to feel involved, so they have student administration boards that make decisions about some of the governing factors. Typically, these student boards make decisions about things like student activities, and are the driving force behind planning those activities.
Community colleges sometimes have private donor funding to account for at least part of their overall funding. If this is the case, community colleges need to have those donors as part of the administration or governance, because those donors are more likely to give money if they feel that they have input over the way the school is run. Most of the time, donors or representatives sit on the board of education that helps make decisions about the school and how it is run.
