| † Not applicable. ! Interpret data with caution. Estimate is unstable due to high coefficient of variation. ‡ Reporting standards not met. * p<.05. Significantly different from both the U.S. and OECD averages at the .05 level of statistical significance. ** p<.05. Significantly different from the OECD average at the .05 level of statistical significance. *** p<.05. Significantly different from the U.S. average at the .05 level of statistical significance. NOTE: To reach a particular proficiency level, a student must correctly answer a majority of items at that level. Students were classified into mathematics literacy levels according to their scores. Exact cut scores are as follows: below level 1 (a score less than or equal to 357.77); level 1 (a score greater than 357.77 and less than or equal to 420.07); level 2 (a score greater than 420.07 and less than or equal to 482.38); level 3 (a score greater than 482.38 and less than or equal to 544.68); level 4 (a score greater than 544.68 and less than or equal to 606.99); level 5 (a score greater than 606.99 and less than or equal to 669.30); and level 6 (a score greater than 669.30). Scores are reported on a scale from 0 to 1,000. The National School Lunch Program provides free or reduced-price lunch for students meeting certain income guidelines. The percentage of students receiving such lunch is an indicator of the socioeconomic level of families served by the school. Data in this table are based on principals' responses to a question in the school questionnaire that asked the approximate percentage of eligible students in the school during the previous school year. The OECD average is the average of the national percentages of the OECD member countries, with each country weighted equally. Standard error is noted by s.e. Free or reduced price-lunch data are for public schools only. Detail may not sum to totals because of rounding.
