I hope that you are just now not forming your nomination committee. Typically a nomination committee would form 2-3 months prior to an election. They can assume many responsibilities about seeking the best person for a person. Not always the current volunteers that serve on a board and have chosen to return. The nomination committee should look at areas of strengths of all volunteers and plug in to those volunteers that could serve and represent the school in the best manner. Nomination Committees should be formed prior to an election and have an odd number of members on it. It would be best that serving on this committee not any volunteers that are wishing to be nominated for an office, however, can be done with the correct format when talking about that particial position. Good luck - I found great info from a website called schoolonline - I believe. I searched the web under PTO nomination committee responsibility. Hope you find this helpful. Good luck, the nomination committee plays a very important role to the success of the PTO's future.
there was a previous discussion about nomination and election guidelines under "rigged elections" in a previous chat forum of robts. rules and bylaws etc. you can look there for some help.
