1National Defined Population covers 90 to 95 percent of National Target Population (see appendix A of source publication).
2Nearly satisfied guidelines for sample participation rates after replacement schools were included.
3National Defined population covers less than 90 percent, but at least 77 percent of National Target population (see appendix A of source publication).
4National Target Population does not include all of the International Target Population (see appendix A of source publication).
5Exclusion rates for Georgia are slightly underestimated as some conflict zones were not covered and no official statistics were available.
6The TIMSS & PIRLS International Study Center has reservations about the reliability of the average achievement score because the percentage of students with achievement too low for estimation exceeds 15 percent, though it is less than 25 percent.
NOTE: Education systems are ordered by percentage at Advanced international benchmark. Italics indicate participants identified and counted in this report as an education system and not as a separate country. "Education system" is defined on page 1 of source publication. The TIMSS international median represents all participating TIMSS education systems, including the United States, shown in the main part of the figure; benchmarking education systems are not included in the median. Participants that did not administer TIMSS at the target grade are not shown; see the international report for their results. All U.S. state data are based on public school students only. The Science scale ranges from 0 to 1000. Standard error is noted by s.e.
