Figure T3a. Cut scores of U.S. 15-year-old students on PISA reading literacy scale at selected percentiles: 2000, 2003, 2006, 2009, and 2012

* p<.05. Significantly different from the 2012 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) 50th percentile- the median (half the students scored below the cut score and half scored above it); (d) 75th percentile- the top 25 percent of students; (e) 90th percentile- the top 10 percent of students. The percentile ranges are specific to each education system's distribution of scores and to each assessment administration, enabling users to compare scores at the cut scores across education systems and over time. The PISA 2006 reading literacy results are not reported for the United States because of an error in printing the test booklets. For more details, see Baldi et al. 2007 (available at http://nces.ed.gov/pubsearch/pubsinfo.asp?pubid=2008016). Scores are reported on a scale from 0 to 1,000.
