This presentation was given at the ECHA conference in Munster, Germany in September 2012. The focus of this presentation was international test scores in Mathematics from TIMSS (Grades 4 and 8) and PISA (Age 15). The presentation shows rankings on total mean scores in Math, as well is sub-score data. The sub-score data is extremely insightful in showing distribution of scores in Number Sense, Algebra, and Geometry, as well as according to thinking skills. Most important in relation to Gifted & Talented is the data for students at the 90th percentile, and the comparison of math scores based on gender. The results shown can be used in comparing important sub-scores and planning alternative emphasis on math topic concentration based on TIMSS International Benchmarks and PISA Proficiency Levels. The last slides of the presentation have three spreadsheet pages showing a overview of test scores for any countries that participated in any of the testing. It is recommended that these three pages be printed out and used as a ready reference whenever discourse makes reference to international test scores.
