A fourth candidate has filed to run for the Jefferson County school board’s district 7 seat, which includes eastern parts of the county.Marty Bell recently resigned from his position as chief academic officer with Indiana's Greater Clark County Schools and he spent years in JCPS serving as a deputy superintendent.Bell will be running against James Sexton, the principal at Jeffersonville High School in Indiana, Chris Fell, who is currently involved in a lawsuit challenging the JCPS student assignment plan, and Chris Brady, who is backed by current District 7 board member Larry Hujo.Bell said his nearly 20 years of service in JCPS sets him apart from other candidates.“I probably know the school system as well as or better than most people in the community. I know it from the inside and I know it from the outside," he said.Bell said he supports the most recent changes to the student assignment plan and is an opponent of charter schools. His approach to problem solving is pragmatic, he said.“I spent 20, 25 years of my career being data driven," said Bell. Joe Hardesty’s District 4 seat and Steve Imhoff’s District 2 seat are also up for election.
