I don't know what an Arts in Education position is, but I would say go with the bylaws. If you really feel like you need another Board position, you can include it when you revise your bylaws.
Some groups in this area have two VPs and/or two secretaries (one keeps the minutes (recording secretary) and the other corresponds with members on meeting announcements, etc. (corresponding secretary). I think that having an even number of Board positions could create a problem when you go to vote on something and you end up with a tied vote..... So just for that reason, I would be inclined to add some sort of 5th position.
This past year our PTG was run by mostly 2 teachers and 2 parents. We finally found some new parents to join our elections for our PTG after weeks of searching. But, several people have told me that my Arts in Education position was added as a board member years ago, but when looking in the by-laws it is not listed as one. Should we go with the word of others or by the paperwork on this?
The other teacher and myself really feel at least one teacher should be a part of the board to help the new faces understand our buildings dynamics. Is this AIE position an executive board position in anyone else's groups? Or, besides president, vice president, treasurer, and secretary, is there any other positions on your boards? We are considering revising our by-laws if necessary so any suggestions would be greatly appreciated.
