# Rounds to zero.

! Interpret data with caution. (Estimates are unstable.)

‡ Reporting standards not met.

*p<05. Difference is statistically significant.

NOTE: Results based on students' self-reports. The OECD average is the average of the national averages of the OECD member countries. Because PISA is principally an OECD study, the results for non-OECD jurisdictions are displayed separately from those of the OECD countries and are not included in the OECD average. The tests for significance take into account the standard error for the reported difference. Thus, a small difference between the United States and one jurisdiction may be significant while a large difference between the United States and another jurisdiction may not be significant. Standard errors are noted by s.e. Detail may not sum to totals because of rounding.
