Longitudinal Data Systems

Longitudinal data systems are useful tools capable of tracking a variety of student and school information over multiple years, and often in multiple schools. AIR’s expertise in using these systems for student assessments, user friendly reporting, value added modeling, and identifying highly effective teachers help states and districts answer the next generation of policy and practice-relevant questions.

Recent Reports

  • The Project Talent Twin and Sibling Study

    This article, recently published in Twin Research and Human Genetics, focuses on Project Talent’s unique design that includes twins, siblings of twins, and siblings in other families all nested within schools. Project Talent is a national longitudinal study of about 377,000 students who were in grades 9-12 in 1960.

  • Selecting Growth Models for School and Teacher Evaluations

    The specifics of how growth models should be constructed and used to evaluate schools and teachers is a topic of lively policy debate in states and school districts nationwide. In this paper we take up the question of model choice and examine three competing approaches.

  • Examining NAEP Achievement in Relation to School Testing Conditions in the 2010 Assessments

    This study examined NAEP testing conditions in schools and investigated whether being assessed in less than optimal testing conditions is associated with lower student achievement on the assessments.

Recent Projects

  • National Household Education Survey (NHES)

    AIR’s experts provide support for all aspects of the National Household Education Survey (NHES), a program that provides descriptive data on the educational activities of the U.S. population.

  • Schools and Staffing Survey (SASS)

    The Schools and Staffing Survey (SASS), sponsored by the National Center for Education Statistics (NCES), is an integrated sample survey of public and private schools, school districts, principals, teachers, and public school libraries. SASS data, which are collected every four years, inform decision makers and provides researchers with a wealth of relevant data on the nation’s elementary and secondary schools. AIR provides support for all aspects of SASS.

  • Trends in International Mathematics and Science Study (TIMSS)

    The Trends in International Mathematics and Science Study (TIMSS) is an international comparative study of the mathematics and science achievement of fourth- and eighth-graders in the United States and students in the equivalent of fourth and eighth grade in other participating countries.
