## Mathematics Percentiles

Figure T3a. Average scores and percentile scores of U.S. 15-year-old students on the PISA mathematics literacy scale at selected percentiles: 2003, 2006, 2009, 2012, and 2015

* p<.05. Significantly different from the 2015 score at the .05 level of statistical significance.
NOTE: This table shows the threshold (or cut) score for the following: (a) 10th percentile- the bottom 10 percent of students; (b) 25th percentile- the bottom 25 percent of students; (c) 75th percentile- the top 25 percent of students; (d) 90th percentile- the top 10 percent of students. The 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, 2009, 2012 and 2015. Scores are reported on a scale from 0 to 1,000.
