Linking the National Assessment of Educational Progress (NAEP) and the Third International Mathematics and Science Study (TIMSS) : Eighth-Grade Results. Research and Development Report / Eugene G. Johnson and Adriane Siegendorf.

Because education in the United States is largely determined at the state and local levels, there has been considerable interest in how the performance of students in individual states compares with each other, with the United States as a whole, and with other nations. The comparison of state performance with other states and with the nation as a whole is made possible by the National Assessment of Educational Progress (NAEP). In 1996, NAEP assessed mathematics and science in the United Sates as a whole. The Third International Mathematics and Science Study (TIMSS) conducted in 1995 provides the most recent information about America's progress in mathematics and science education compared with other countries in the world. This study is one of two reports about the linking of NAEP results to TIMSS results for Grade 8 mathematics and science. The study describes the types of linking approaches considered, the methods used to develop the linking functions, the sources of variability that affect the variance of the linking functions, and the validation and results obtained for Grade 8 mathematics and science achievement.
