* p < .05. Significantly different from the average in 2009 at the .05 level of statistical significance. NOTE: The Organization for Economic Cooperation and Development (OECD) trend average used for the analysis of mathematics literacy trends is based on the averages of the 29 OECD countries with comparable data for 2003 and 2009, with each country weighted equally. The OECD trend average used for the analysis of science literacy trends is based on the averages of the 34 OECD countries with comparable data for 2006 and 2009, with each country weighted equally. In the Program for International Student Assessment (PISA), proficiency in both mathematics and science was defined in terms of levels based on student performance scores. Mathematics literacy was assessed along a continuum, with proficiency below level 2 indicative of the low-performing students and proficiency level 5 and above indicative of the high-performing students. In mathematics, proficiency below level 2 is defined by scoring below 420, and proficiency level 5 and above is defined by scoring 607 and above. Science literacy was assessed along a continuum, with proficiency below level 2 indicative of the low-performing students and proficiency level 5 and above indicative of the high-performing students. In science, proficiency below level 2 is defined by scoring below 410, and proficiency level 5 and above is defined by scoring 633 and above. Scores are reported on a scale from 0 to 1,000.
