For all the jurisdictions in this study, however, the mandatory age for starting school is 6. This is encouraging, but the data does not show improvements at other age levels, and there appear to be slight declines in participation rates at lower secondary levels (Figure 5.7). This is evident in an increase in early-years participation rates between 2010 and 2015.6 More noteworthy, however, are the significant increases in participation rates from 2005 to 2015 for Indigenous students age 14-16 (Figure 5.8).
