Texas ranked highest with 89.0% of public high school students graduating, while New Mexico fell at the bottom with only 68.6% of students graduating.

Why is it important?
Those who do not finish high school are much more likely to be unemployed, and when employed, their earnings fall far below those with a high school degree or higher. This gap can add up to a substantial deficit in earnings over a lifetime. Economic consequences follow through to the community at large with lower wages, less spending power, and the likelihood of higher costs for public assistance. A high school diploma, or its equivalent, is the basic prerequisite to college or trade school.
How do we compare?

How is it measured?
The graduation rate of public high schools is based on the four-year adjusted cohort graduation rate (ACGR). The “cohort” measure of four-year graduation is the share of students who comprise a ninth-grade class and graduate by the fourth year, including transfers into the class, minus those who transfer out and deceased students. For example, those entering ninth grade in the 2008-2009 school year comprise the cohort measured by the 2012 data. State-level graduation rate data comes from the National Center for Education Statistics (NCES). County-level data comes from the Arizona Department of Education. NCES imputed the data from Virginia to come up with the Native American total.
