Understanding Idaho’s Adjusted Cohort Graduation Rate

In 2015, Idaho reported high school graduation rates using a new methodology (adjusted cohort graduation rate or ACGR) required by the federal government. The reported high school graduation rate fell from 84.1% for the Class of 2013 to 77.3% for the Class of 2014. These rates are not comparable as they are based on very different methodologies. Therefore, it cannot be said that the Class of 2014 graduated at a lower rate than the Class of 2013. However, it can be said that graduation rates in Idaho under the new methodology are lower than what most Idahoans anticipated.
