How are we doing?  

Percent of Public High School Students Graduating in Four Years (2015)

In 2015, Arizona had 77.4% of public high school students graduating on time, ranking them sixth out of the 10 western states. 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. Within Arizona, Santa Cruz County had the highest graduation rate, with 88.8% of students graduating with their peers. Graham County had 73.6%, placing it last among Arizona counties.

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?

Arizona followed the same general pattern as the U.S. in 2015, with respect to graduation rates by race and ethnic origin. In both Arizona and nationwide, more Asians graduated on time than any other race or ethnicity. Arizona had 72.7% of Hispanic students and 72.6% of Black or African American students graduating on time, while nationwide, 77.8% and 74.6%, respectively, graduated on time

At 88.8%, Santa Cruz County had the highest percentage of public high school students graduating with their peers in 2015. Graham had only 73.6%, placing it last among Arizona counties. Pima and Pinal tied at 13 out of the 15 counties in Arizona with 74.3% of students graduating on time.

What are the key trends?

The high school graduation rate for the U.S. rose from 79.0% in 2011 to 83.2% in 2015, an increase of 4.2 percentage points over four years. During the same four year period, the percentage of high school students graduating on time in Arizona decreased; although between 2013 and 2015 the state posted an increase of 2.3 percentage points, from 75.1% to 77.4%.

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.
