NAEP-TIMSS Linking Study
NCES initiated this special study in an effort to link the National Assessment of Educational Progress (NAEP) scale to the Trends in International Mathematics and Science Study (TIMSS) scale so that states could compare the performance of their students with that of students in other countries. The study was conducted in 2011 with eighth-grade students in all 52 states/jurisdictions that participated in the NAEP mathematics and science assessments. Read more about TIMSS.
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).
