(BOISE) – The number of Idaho teachers leaving the profession has more than doubled in the past three years. Officials say 1,800 teachers left their jobs for various reasons during the 2011-2012 school year. That’s up from only 700 during the 2009-2010 class. The Idaho Education Association was quick to put the blame on State Superintendent Tom Luna’s education reforms. Luna dismisses the claims, citing grim economic figures nationwide. Luna also notes that the state has seen a 25 percent increase in teacher certifications, and that the number of staff currently working in Idaho’s schools remains largely unchanged.
