The 2011 NAEP-TIMSS linking study conducted by the National Center for Education Statistics (NCES) was designed to predict Trends in International Mathematics and Science Study (TIMSS) scores for the U.S. states that participated in 2011 National Assessment of Educational Progress (NAEP) mathematics and science assessment of eighth-grade students. The purpose of conducting the 2011 NAEP-TIMSS linking study was two-fold. The study was conducted to see whether it is possible to predict TIMSS scores for the states that did not participate in the TIMSS assessment. Secondly, the study was conducted to identify a method among various methodologies suggested in the literature for linking two assessments that are somewhat different.
This 2011 NAEP-TIMSS linking methodology paper was prepared to supplement the reading of U.S. States in a Global Context: Results From the 2011 NAEP-TIMSS Linking Study, NCES 2013-460.
