The Program for International Student Assessment (PISA) is a triennial international survey which aims to evaluate education systems worldwide by testing the skills and knowledge of 15-year-old students. More than 70 economies have participated in the assessment.
The most recently published results are from the assessment in 2012. The next report is scheduled for December 2015.
Around 510,000 students took part in the PISA 2012 assessment of reading, mathematics and science representing about 28 million 15-year-olds globally. Of those economies, 44 took part in an assessment of creative problem solving and 18 in an assessment of financial literacy.
