Term of office
A term of office is the fixed period an appointed or elected member serves before the seat expires and must be filled again, either by reappointment or by someone new.
In Phoenixville
Phoenixville's borough boards run staggered terms of three, four, five or six years, which is why openings appear a few at a time rather than all at once. A seat expiring doesn't mean the holder leaves: Borough Council reappoints members annually alongside new appointments. For anyone interested, that means there's no season for applying. Put the form in whenever you're ready.
