Table 1 Number of common and unique items in the respective mathematics assessments

This table shows item overlaps across the assessments over time. The TIMSS assessments are denoted by T and the last two digits of the year of the assessment cycle. Numbers in the same row represent common items between surveys. The number of items common with the preceding administration is shown in the bridge row. The total number of items in the item pool per administration is shown in the total row. For example, 37 items, which were administered in FIMS, were repeated in SIMS, out of which nine were repeated in TIMSS 1995, then five of these items were also administered in TIMSS 1999, and finally, three of them were included in TIMSS 2003
