1 For TIMSS 2015, Norway revised its assessed population to students in their 5th and 9th year of schooling to obtain better comparisons with Sweden and Finland. However in previous TIMSS cycles Norway assessed students in their 4th and 8th years of schooling, which were defined as 4th and 8th grades but have been redefined as 3rd and 7th grade because year 1 in Norway is now considered the equivalent of a year of Kindergarten. To maintain trend with previous TIMSS cycles, in 2015 Norway also collected data from students in their 4th and 8th years of schooling, which is used in trend tables.
2 Missouri-USA and Oregon-USA participated in the 1997 TIMSS Benchmarking Study, which administered the TIMSS 1995 assessment to 8th-grade students in 1997.
3 Administered the TIMSS 4th-grade assessment to 6th-grade students in 2011.
4 Administered the TIMSS 8th-grade assessment to 9th-grade students in 2011 and 2015.
5 Administered the TIMSS Numeracy assessment to 5th-grade students in 2015.
