Ray Martin says he will seek election this fall as a trustee with the Edmonton Public School Board.
Martin, who served as leader of the New Democrats for nine years, says in a release he wants to ensure that schools in Edmonton's urban core don't fall victim to provincial budget cuts.
Martin, who worked as a physical education teacher and guidance counsellor for 15 years, previously served as an Edmonton public board trustee from 2001 to 2004.
He also served as the NDP's education critic for four years.
The election will be held in October.
