Who+takes+the+tests?

=//Who takes the assessments? //= The subjects for PISA are 15-year-old students from 57 countries which amounts to the total 400,000 who are being tested. "Tests are typically administered to between 4,500 and 10,000 students in each country." The rational for the age requirement is that, in all participating countries, these students are near the end of their K-12 school career. “PISA assesses how far students near the end of compulsory education have acquired some of the knowledge and skills that are essential for full participation in society. In all cycles, the domains of reading, mathematical and scientific literacy are covered not merely in terms of mastery of the school curriculum, but in terms of important knowledge and skills needed in adult life.”
