Expressing International Educational Achievement in Terms of U.S. Performance Standards: Linking NAEP Achievement Levels to TIMSS
Phillips, Gary W.
American Institutes for Research
Educators, researchers, and policymakers have considerable interest in how the American educational system compares to those in other countries. One major index for comparison is student academic achievement. This paper links the scale of the "National Assessment of Educational Progress" ("NAEP") to the scale of the "Third International Mathematics and Science Study" ("TIMSS"). Linking is a process that provides a concordance table that expresses scores on one test (e.g., TIMSS) in terms of the metric of another test (e.g., NAEP). This paper uses statistical moderation to link the NAEP achievement levels to TIMSS by extending the process used in the "2000 NAEP-1999 TIMSS Linking Report" (Johnson et al. 2005). The purpose of this linking is to project the NAEP achievement levels onto the TIMSS scale. More specifically, the grade 8 NAEP: 2000 achievement levels in mathematics and science are projected on to the grade 8 TIMSS: 1999 assessment in mathematics and science. The linking equation is also applied to the 2003 TIMSS in mathematics and science. The goal is to project the grade 8 mathematics and science achievement levels in NAEP onto the TIMSS scale and thereby estimate the percent of basic, proficient, and advanced students in each country that participated in the 1999 TIMSS and 2003 TIMSS studies. The analyses in this paper provide a useful application of NAEP achievement levels. By projecting them onto the TIMSS scale, the NAEP achievement levels provide benchmarks for international comparisons. (Contains 30 tables and 6 footnotes.)
