National Research Coordinators
Each country participating in TIMSS 1999 had a National
Research Coordinator (NRC) who carry out the study in the country, in
accordance with the international procedures and standards. The NRC was
responsible for selecting the school sample, collecting the data, scoring
and data entry, and preparing a national report of the study results.
The ISC convened the NRCs several times a year to discuss and review the
study design, procedures, and instruments, and to conduct training activities.
