This 10th report on teacher quality presents information states reported to the U.S. Department of Education (Department) in October 2012, October 2013, and October 2014. "Title II" of the "Higher Education Act of 1965" ("HEA"), as amended in 2008 by the Higher Education Opportunity Act (HEOA), requires states to report annually on key elements of their teacher preparation programs and requirements for initial teacher credentialing, kindergarten through 12th grade, on a State Report Card designated by the Secretary. For many data elements, such as the number of individuals enrolled in and completing teacher preparation programs, states reported on AY 2010-11 data in 2012, AY 2011-12 data in 2013, and AY 2012-13 data in 2014. For other data elements, such as the admission requirements for each teacher preparation program and descriptions of the state's alternative routes to a teacher credential, states reported on the most current information available each year. The 10th report provides a national overview of the state data by key topics collected through the State Report Cards, including graphics showing "Title II" longitudinal trends over more than a decade of state reporting. Similar to previous reports, the report is organized into chapters, with each summarizing states' data on "HEA Title II" key elements. The chapters are: (1) Teacher Preparation Providers and Programs; (2) Teacher Preparation Program Participants; (3) Institutions of Higher Education Offering Teacher Preparation Programs; (4) State Standards for Teaching Credentials; (5) Evaluation of Teacher Preparation Programs; (6) Assessments Required for an Initial Teaching Credential; and (7) State Initial Credentials for Teachers.
