Michigan lags behind the nation in graduation rates, according to a new report.

The report, by a variety of groups including Civic Enterprises, the Everyone Graduates Center at Johns Hopkins University, America's Promise Alliance and the Alliance for Excellent Education, shows only 76-percent of Michigan high school students graduate on time, compared to 81-percent nationally.

The report also shows just 64-percent of Michigan's low-income students graduate within the usual four years, while the rate for non low-income students is 85-percent.

Iowa had the nation's highest graduation rate at 89-percent, while Nevada was lowest at 63-percent.
