|Method Of Calculation
|PISA ranks participating countries and economies according to their performance in reading, mathematics and science. PISA does not give a collective score for all subjects combined; rather it gives a score for each subject area, and the mean score in each subject can be used to rank countries. However, even within a single subject, it is not possible to assign an exact rank to each country or economy based on its mean score. This is because PISA tests only a sample of students from each country or economy, and estimates, based on their results, the distribution of performance in the whole population of 15-year-old students. The statistical uncertainty associated with these estimates means that it is only possible to report the range of positions (upper rank and lower rank) within which a country or economy can be placed. For example, in PISA 2003 Finland and Korea were widely reported as ranking 1st and 2nd in PISA, when in fact we can only say that, among OECD countries, Finland’s rank was between 1st and 3rd and Korea’s was between 1st and 4th.
