About U.S. TEDS-M
The Teacher Education Study in Mathematics (TEDS-M) is an international study focusing on the preparation of teachers of mathematics at the elementary and middle school levels. In the U.S. the focus has been extended to include future high school mathematics teachers. The research is a project of the International Association for the Evaluation of Educational Achievement (IEA), the agency that sponsors cross-national studies including the Third International Mathematics and Science Study (TIMSS). This project builds on the results of TIMSS and breaks new ground as the first large-scale international study to examine how teachers are prepared to teach.
