Figure CL-10. Change in average PISA mathematics scores of 15-year-old students in selected jurisdictions, by jurisdiction: 2003 to 2006
Average score was higher than the U.S. average score.
Average score was lower than the U.S. average score.
# Rounds to zero. 1 The Republics of Montenegro and Serbia were a united jurisdiction for the PISA 2003 assessment.
NOTE: Selected jurisdictions include those that participated in both PISA 2003 and PISA 2006. Mathematics results from PISA 2000 cannot be
compared with mathematics results from PISA 2006 due to changes in the assessment framework; as such, mathematics results from PISA 2003
served as the basis of comparison. Average mathematics literacy scores are reported on a scale from 0 to 1,000. Tests for statistical significance
take into account the standard errors for scores in both years and the linking error across assessments. For more information on linking error,
see appendix A. Because the size of standard errors can vary, a small difference between the scores of one jurisdiction may be significant while
a larger difference between the scores of another jurisdiction may not be significant. Detail may not sum to totals due to rounding.
