This National Center for Education Statistics (NCES) report introduces new data for two separate measures of 4-year on-time graduation rates as well as event dropout rates for school year (SY) 2010-11 and SY 2011-12. Specifically this report provides the following: (1) Four-year adjusted cohort graduation rate (ACGR) data reported by state or jurisdiction and, for the first time, a national estimated 4-year cohort graduation rate; (2) Averaged freshman graduation rate (AFGR) data by state or jurisdiction and a national estimated AFGR; and (3) High school event dropout rate data by state or jurisdiction and a national estimated event dropout rate. Both the AFGR and ACGR are 4-year on-time graduation rates that provide measures of the percent of students that successfully complete high school in 4 years with a regular high school diploma. Event dropout rates provide a measure of the percentage of students who drop out in a single year. The findings chosen for this report provide only a few examples of how the graduation and dropout data may be used.
