Table B.1.60. Average scores of U.S. 15-year-old students on mathematics literacy scale, by selected percentiles: 2003, 2006, and 2009
Selected percentiles 2003   2006   2009
Score   s.e.   Score   s.e.   Score   s.e.

U.S. average 483   2.9   474 * 4.4   487   3.6
* p < .05. Significantly different from the 2009 score at the .05 level of statistical significance.
NOTE: This table shows the threshold (or cut point) score for the following: (a) 5th percentile – the bottom 5 percent of students; (b) 10th percentile – the bottom 10 percent of students; (c) 25th percentile – the bottom quarter of students; (d) 50th percentile – the median (half the students scored below the cut point and half scored above it); (e) 75th percentile – the top quarter of students; (f) 90th percentile – the top 10 percent of students; and (g) 95th percentile – the top 5 percent of students. The percentile ranges are specific to each country's distribution of scores and to each assessment administration, enabling users to compare scores at the cut points across countries and over time. The Program for International Student Assessment (PISA) mathematics framework was revised in 2003. Because of changes in the framework, it is not possible to compare mathematics learning outcomes from PISA 2000 with those from PISA 2003, 2006, and 2009. Scores are reported on a scale from 0 to 1,000. Standard error is noted by s.e.
