Parliamentarians are expected to be experts in meeting procedures and such books as ''
Robert's Rules of Order Newly Revised'' as well as the rules of the body they are working for. A parliamentarian may be called in to assist in drafting bylaws. Other responsibilities may include teaching classes or holding office hours during conventions. Generally, the parliamentarian's role is purely advisory. At meetings, the parliamentarian should unobtrusively call the attention of the presiding officer to serious errors in procedure. If the parliamentarian is a member of the assembly, that person has the same rights as other members, but should strive to maintain impartiality, similar to the impartiality that is required of the chairman. In other words, the parliamentarian should ordinarily not be making motions, speaking in debate, or voting. == Certification ==
