The database that will be used is from PISA (Programme for International Student Assessment). PISA is the OECD's Programme for International Student Assessment. PISA measures 15-year-olds’ ability to use their reading, mathematics and science knowledge and skills to meet real-life challenges. The dataset contains mean (Pisa) attainment scores in math, reading and science by country and gender.

PISA is not only the world’s most comprehensive and reliable indicator of students’ capabilities, it is also a powerful tool that countries and economies can use to fine-tune their education policies. 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.
