U.S. Secretary of Education Arne Duncan will host a conference call today at 3:00 p.m. ET on the release of this year's college cost lists on the Department’s College Affordability and Transparency Center, which includes schools with the highest and lowest tuition and net price, and those schools where tuition prices are rising the fastest. For the first time this year, the Department is also releasing full lists of tuition and net prices for all postsecondary institutions from all sectors.
