1 Program for International Student Assessment (PISA) scores are reported on a scale from 0 to 1,000.
2 To reach a particular proficiency level, a student must correctly answer a majority of items at that level. Students were classified into science literacy levels according to their scores. Exact cut scores are as follows: below level 1b (a score less than 260.54); level 1b (a score of at least 260.54 but less than 334.94); level 1a (a score of at least 334.94 but less than 409.54); level 2 (a score of at least 409.54 but less than 484.14); level 3 (a score of at least 484.14 but less than 558.73); level 4 (a score of at least 558.73 but less than 633.33); level 5 (a score of at least 633.33 but less than 707.93); and level 6 (a score of at least 707.93).
3 Refers to the mean of the data values for all Organization for Economic Cooperation and Development (OECD) countries, to which each country contributes equally, regardless of the absolute size of the student population of each country.
4 Results are for public school students only.
