The Institute is led by John Q. Easton, who began his six-year term as director on June 1, 2009. The work of the Institute is carried out through our four Centers: the National Center for Education Research, the National Center for Education Statistics, the National Center for Education Evaluation and Regional Assistance, and the National Center for Special Education Research. Established under the Education Sciences Reform Act of 2002, IES operates with the counsel and oversight of the National Board for Education Sciences…(more available at http://ies.ed.gov/)

How the NAEP-TIMSS Linking Study Works

NCES coordinated efforts across the NAEP and TIMSS assessment programs to conduct the 2011 NAEP-TIMSS linking study. The National Assessment Governing Board and NCES modified the NAEP assessment schedule so that eighth-graders in all 50 states, the District of Columbia, and the Department of Defense schools (referred to as “states” or U.S. states) could be assessed in mathematics and science in 2011.

The NAEP-TIMSS linking study used states’ NAEP scores to predict performance on TIMSS. Nine states participated in 2011 TIMSS at the state level. In the linking study, their actual TIMSS scores were used to validate their predicted results.

The 38 countries and 9 subnational education systems from various countries that assessed eighth-graders in 2011 TIMSS are all referred to as “education systems” on this website and in the report. Results in mathematics and science are reported as average scores on the TIMSS scale (0–1,000, with an average of 500).

Cautions in Interpreting NAEP Results

NAEP assessment results make it possible to examine relationships between students’ academic performance and the varied background information collected by NAEP. A relationship that exists between achievement and another variable, however, does not reveal its underlying cause, which may be influenced by a number of other variables. Simple or causal inferences related to, for example, student group membership, the effectiveness of public and nonpublic schools, and state- or district-level education systems cannot be drawn using NAEP results.
