The Science and Mathematics Item Review Committee (SMIRC) met in Seoul, Korea, in May to conduct scale anchoring for TIMSS and TIMSS Advanced. In scale anchoring, SMIRC members also review student performance on the TIMSS and TIMSS Advanced achievement items to develop descriptions of the mathematics and science that students reaching the International Benchmarks know and can do.
SMIRC members reviewed student performance on hundreds of mathematics and science items before writing descriptions of the International Benchmark levels, and selected example items to illustrate the skills students demonstrate at each of the international benchmarks.
