PISA: 15-year-olds by science proficiency level (%). Level 1A — every country, all years (World Bank)

Percentage of 15-year-old students scoring higher than 335 but less than or equal to 410 on the PISA science scale. At Level 1A, students are able to use basic or everyday content and procedural knowledge to recognise or identify explanations of simple scientific phenomenon. With support, they can undertake structured scientific enquiries with no more than two variables. They are able to identify simple causal or correlational relationships and interpret graphical and visual data that require a low level of cognitive demand. Level 1a students can select the best scientific explanation for given data in familiar personal, local and global contexts. Data reflect country performance in the stated year, but may not be comparable across years or countries. Consult the PISA website for more detailed information: http://www.oecd.org/pisa/ Every country, region and year the World Bank publishes for indicator LO.PISA.SCI.1A (Education Statistics), delivered as a tidy table — country, ISO code, year and value — ready for analysis in Excel, R, Python or the Intigal AI workspace. Original compiler: OECD Programme for International Student Assessment (PISA).
