There may soon be no limits on the term of School Board chairman if a measure before the board of education passes on second reading.Presently the School Board takes turns passing the chairmanship around. A new chairman is nominated and voted into the position each year, meaning the chairman never serves for more than one year. The reason behind the policy, which could be done away with as early as the next School Board meeting this month, was to spread out the experience of being chair throughout the board.“There are certain levels of School Board certification through the state that requires the person to serve as local board chairman to achieve that next step,” said Warren County Director of Schools Bobby Cox.
