* The difference between the PISA 2000 and PISA 2009 estimated average scores is statistically significant (p < 0.05).
Notes: The Programme for International Student Assessment (PISA) reports on reading, mathematics and science every three years, providing a more detailed look at each domain in the years when it is a major focus: reading in 2000 and 2009, mathematics in 2003, and science in 2006.
The confidence interval represents the range within which the score for the population is likely to fall, with 95% probability. It is calculated as a range of plus or minus about two standard errors around the estimated average score. The difference between estimated average scores are statistically significant if the confidence intervals do not overlap. When confidence intervals overlapped slightly, an additional t-test was conducted to confirm statistical difference.
Performance differences should be interpreted with caution. It is not possible to determine the extent to which observed differences are indicative of longer-term changes.
The 2009 standard errors and confidence intervals include linking errors associated with the uncertainty that results from making comparisons with PISA 2000. To compare the performance of Canada or of provinces in a particular assessment year with that of other countries, economies or provinces, the PISA Canada report for that year should be consulted.
For a brief description of this indicator, including the methodology, please see the Handbook for the Pan-Canadian Education Indicators Program.
