The Program for International Student Assessment (PISA) is a global education study of 15-year-old students' reading, mathematics, and science literacy and, in 2015, two optional components: financial literacy and collaborative problem solving. Fifty-one education systems administered the collaborative problem solving assessment, including 32 of 35 OECD-member education systems. Students were assessed on their ability to solve a problem by sharing the understanding and effort required to come to a solution, and pooling their knowledge, skills and effort to reach that solution (OECD 2017). Assessment results are reported on a scale of 0-1,000, and also in terms of the percentage of students performing at four proficiency levels. This document provides information on how U.S. 15-year-olds perform, on average, on the PISA collaborative problem solving assessment in 2015, as well as the percentage distribution of U.S. students across the proficiency levels on the PISA collaborative problem solving assessment.
