In information-rich environments, schools are often presented with a myriad of data from which decisions need to be made. The use of the information on a classroom level may be facilitated if performance could be described in terms of levels of proficiency or benchmarks. The aim of this article is to explore benchmarks using data from a monitoring…

As the largest international study ever taken in history, the Trend in Mathematics and Science Study (TIMSS) has been held as a benchmark to measure U.S. student performance in the global context. In-depth analyses of the TIMSS project are conducted in this study to examine key issues of the comparative investigation: (1) item flaws in mathematics…

In this paper we report some results of the analysis of released items of the Third International Mathematics and Science Study (TIMSS). This analysis is part of a research project in process related to Mexican high school curricula from an international perspective and, the mathematics students' performance in this school level. The results…
