The new, uniform rate calculation is not comparable in absolute terms to previously reported rates. Therefore, while 26 states reported lower graduation rates and 24 states reported unchanged or increased rates under the new metric, these changes should not be viewed as measures of progress but rather as a more accurate snapshot.
"By using this new measure, states will be more honest in holding schools accountable and ensuring that students succeed," said U.S. Secretary of Education Arne Duncan. "Ultimately, these data will help states target support to ensure more students graduate on time, college and career ready."
The transition to a common, adjusted four-year cohort graduation rate reflects states' efforts to create greater uniformity and transparency in reporting high school graduation data, and it meets the requirements of October 2008 federal regulations. A key goal of these regulations was to develop a graduation rate that provides parents, educators and community members with better information on their school's progress while allowing for meaningful comparisons of graduation rates across states and school districts. The new graduation rate measurement also accurately accounts for students who drop out or who do not earn a regular high school diploma.
In 2011, states began individually reporting 2010-11 high school graduation rates, but this is the first time the Department has compiled these rates in one public document. These 2010-11 graduation rates are preliminary, state-reported data, and the Department plans to release final rates in the coming months. Beginning with data for the 2011-12 school year, graduation rates calculated using this new method will become a key element of state accountability systems, including for states that have been approved for ESEA flexibility.
The rates will be posted in the coming days on ED Data Express: http://www.eddataexpress.ed.gov/.
