Northern Lehigh School District hopes to have a vacant seat on its school board filled soon.

The school board has called for a special meeting at 7 p.m. Monday to interview candidates for the post.A look at the board's regular monthly meeting agenda available on its district website has the item listed for action.The board's regular monthly meeting is scheduled for 7:30 p.m. Monday.Candidates were originally asked to turn in letters of application to the district by 3 p.m. March 23.However, after no letters were received, the district extended the deadline until 3 p.m. Monday.The seat became open after Director Edward Hartman resigned last month, though no reason was given for his departure.Board President Gary Fedorcha said at that time Hartman's resignation was believed to be due to personal reasons.Hartman joined the board in December 2007, and most recently served as its vice president, after having spent much of his tenure as board president.Whoever is chosen to fill the vacancy will serve until December.To serve beyond then, it will be necessary to run in the municipal election.
