The seniority system is most often used method to select committee chairs.
The parliamentary head of a committee is the committee chair. The committee's chair controls the agenda, deciding when bills will be reviewed or, in many states, if they will be. A committee chair's other tasks often include: convening the committee to do its business.
Vice-chair, secretary, treasurer, and chair. Additional posts, such as those for a publicity officer, a entertainment officer, an membership officer, or even a fundraising officer, would be desirable. What kind of committee should there be? 12 to 15 people make up the majority of committees.
The longest-serving committee members from the majority & minority parties are chosen as the chair & ranking member, respectively. This practise of choosing committee chairmen by seniority is not exclusive, however.
