|Figure 29-2: Percentage of fourth-grade and eighth-grade students whose mathematics teachers reported that they participated in mathematics assessment professional development activities in the 2 years prior to assessment, by country: 2007|
1 Eighth grade data for England met international guidelines for participation rates in 2007 only after substitute schools were included.
2 Data for Germany are only available at the fourth grade because Germany did not participate in TIMSS 2007 at the eighth grade.
