North Wasco County School District 21 board members are beginning to discuss reducing the number of zones members represent and adding an at-large position.  Currently each board member represents one of seven zones, but the group is now considering dropping to six zones and including an at-large seat.  Superintendent Candy Armstrong says that is because they have had difficulty filling the zone three seat, which is in the western end of The Dalles and is currently vacant.  She adds each zone must be divided equally by population.  Armstrong says the board has just begun discussing the concept.  If the D-21 board decides to make a change, it needs to be finalized by November to allow the at-large seat to be a part of school board elections in May.
