National Research Coordinators

Each country participating in TIMSS appoints a National Research Coordinator (NRC) who carries out the study in the country, in accordance with the international procedures and standards. The NRC is responsible for selecting the school sample, collecting the data, conducting scoring and data entry, and preparing a national report of the study results. The TIMSS International Study Center convenes the NRCs several times a year to discuss and review the study design, procedures, and instruments, and to conduct training activities.
