Idaho’s high school graduation rate dropped to its lowest point in a decade in 2012-13, Kevin Richert of Idaho Education News reports, but the drop largely reflects a bookkeeping change. Idaho is now complying with tougher federal reporting requirements for how it calculates dropout rates, requiring it to track every student – even if they just transfer to another school. If a student isn’t accounted for, that student now counts as a dropout.

The change meant Idaho’s 2012-13 graduation rate came in at 83.6 percent, Richert reports, down from 89 percent in 2011-12 and 93 percent in 2010-11. But some school officials say it’ll mean better reporting and tracking of all students. Richert’s full report is online here.
