Ninety-three of Idaho's 115 school districts are now collecting supplemental levies – voter-approved property tax increases designed to supplement thin school budgets – up from 91 districts a year ago, reports Kevin Richert of Idaho Education News. It’s a trend that’s been growing since Idaho’s state funding for schools was cut during the economic downturn. Richert reports that during Gov. Butch Otter’s eight years in office thus far, Idahoans have approved more than $1 billion in property taxes to backfill school district budgets; this year’s total dollar amount fell slightly, even as more districts passed levies. Richert’s full report is online here.
