Data Source: 
Common Core of Data (CCD); Department of Education, National Center for Education Statistics (ED/NCES)
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent
Baseline (Year): 
79 (2010–11)
Target: 
87
Target-Setting Method: 
10 percent improvement
Numerator: 

Number of students who earned a regular high school diploma by the end of the school year four school years after starting 9th grade for the first time

Denominator: 

Number of first-time 9th graders in the fall of that school year (starting cohort) plus students who transferred in, minus students who transferred out, emigrated, or died during that school year and the three subsequent school years

Comparable Healthy People 2010 Objective: 
Not applicable
Data Collection Frequency: 
Annual
Leading Health Indicator:
Adolescent Health
Methodology Notes: 

    The on-time high school graduation rate measures the percent of high school students that graduate within 4 years of starting ninth grade.

    The four-year regulatory adjusted cohort graduation rate (ACGR) is used for this measure. The ACGR is defined as the number of students who graduate in four years or less with a regular high school diploma divided by the number of students who form the adjusted cohort for the graduating class. In order to calculate and report the 4-year ACGR, states must follow the progress of each individual 9th-12th grade student over time and maintain documentation of students who enter or leave schools or districts within their state. From the beginning of ninth 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 from another state and subtracting any students who subsequently transfer out, emigrate to another country, or die.

Trend Issues:

Exceptions for the 2010-11 school year were: data were imputed for Idaho, Kentucky, and Oklahoma.
Exceptions for the 2011-12 school year were: data were imputed for Idaho, Kentucky, and Oklahoma.
Exceptions for the 2012-13 school year were: data were imputed for Idaho.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
The Averaged Freshman Graduation Rate (AFGR) was previously used to measure this objective. In May 2015, the measure used for this objective was changed to the 4-year adjusted cohort graduation rate (ACGR). As a result the baseline, baseline year, and target were revised. The baseline changed from 74.9% to 79%. The baseline year changed from 2007-08 to 2010-11. The target was adjusted from 82.4% to 87% to reflect the revised baseline using the original target setting method.
