"U.S. Performance on the 2015 TIMSS Advanced Mathematics and Physics Assessments: A Closer Look" expands upon the results described in NCES' [National Center for Education Statistics'] initial "Highlights" report on TIMSS Advanced. This new report provides in-depth analyses that (1) examine the demographics, school…

This revised data file includes corrections that were provided to NCES as a result of a special collection effort designed to address data quality issues found in the 1a release of this file.

Information is then presented on topics on which students are doing well…
