Democratic schools often have meetings open to all students and staff, where everyone present has a voice and sometimes an equal vote. Some include parents.[26] These school meetings can cover anything from small matters to the appointment or dismissal of staff and the creation or annulment of rules, or to general expenditure and the structure of the school day. At some schools all students are expected to attend these meetings, at others they are voluntary.[27] The main school meeting may also set up sub-committees to deal with particular issues, such as conflict resolution.
