(Portland, WA)  --  The lone finalist for the Portland Public Schools superintendent's job is no longer under consideration.  Officials say Doctor Donyall Dickey has withdrawn his candidacy and officials say it was a mutual decision.  Dickey had expressed interest in exploring other interests while serving as superintendent, but PPS Board chair Tom Koehler says the board made it clear it wanted a superintendent who would be with Portland Public Schools 100-percent.  Bob McKean will continue as interim superintendent.
