Figure CL-9. Percentage distribution of 15-year-old students on PISA mathematics literacy scale, by proficiency level and jurisdiction: 2006
*p < .05. Percentage at proficiency Level 6 is measurably higher than U.S. percentage.
# Rounds to zero.
NOTE: Jurisdictions are ordered by the percentage of students scoring 669.30 or above on a scale from 0 to 1000. Students with a score of 420.07
or lower appear on the left side of the percentage distribution. These students performed at proficiency level 1 or below. At Level 1 students
can answer questions involving familiar contexts where all relevant information is present and the questions are clearly defined. They are able
to identify information and to carry out routine procedures according to direct instructions in explicit situations. They can perform actions that
are obvious and follow immediately from the given stimuli. The Program for International Student Assessment (PISA) has defined six levels of
proficiency based on specific student proficiencies. These specific student proficiencies remain the same across all PISA assessments; however,
the score point threshold for students who demonstrate these specific student proficiencies may vary slightly from assessment to assessment.
Because OECD proficiency levels are anchored by specific student proficiencies (i.e., by items not scores), the percentage distribution by level
can be reported. Apparent differences may not be statistically significant.
