Iowa once again leads the nation in the percentage of high school students who graduate.

Iowa Department of Education director, Ryan Wise, says 91.3-percent of students in the class of 2016 completed high school within four years in Iowa and a national report says that the best in the country. The 2016 graduation rate in Iowa was up three-tenths of a percent from the year before and is up three percentage points during the last six years.

The national graduation rate is about seven percent lower at 84.1-percent. New Jersey was the only other state to top 90 percent — at 90.1.

Wise says the graduation rate is just one measure of success as the state has work to do to ensure all the graduates are prepared to succeed beyond high school.
