New data from the U.S. Education Department shows that 81 percent of high school students graduated in four years in 2012-13, the latest year for which there is data. As my colleague Emma Brown reported here, this represents the highest national graduation rate since 2010, when the federal government required states to calculate graduation rates the same way.

While the national rate is 81 percent, there are large differences among states.  For example, Oregon had a 69 percent graduation rate, while Iowa’s was 90 percent.

Here’s the state-by-state list, from the National Center for Education Statistics. The list includes the District of Columbia as a state, even though it isn’t, a common if unfair practice by government agencies.

1 The United States 4-year ACGR was estimated using both the reported 4-year ACGR data from reporting states and the District of Columbia and using imputed data for Idaho, Kentucky, and Oklahoma for school years 2010-11 and 2011-12, and imputed data for Idaho for school year 2012-13.
2 School year 2011-12 data for California, Hawaii, and Missouri were revised subsequent to the publication of these data in NCES 2014-391. The estimated United States ACGR includes these revisions.
3 The Department of Education’s Office of Elementary and Secondary Education approved a timeline extension for these states to begin reporting 4-year ACGR data, resulting in the 4-year ACGR not being available in one or more of the school years shown.
NOTE: The 4-year ACGR is the number of students who graduate in 4 years with a regular high school diploma divided by the number of students who form the adjusted cohort for the graduating class. From the beginning of 9th grade (or the earliest high school grade), students who are entering that grade for the first time form a cohort that is “adjusted” by adding any students who subsequently transfer into the cohort and subtracting any students who subsequently transfer out, emigrate to another country, or die.
