The PISA 2018 Assessment and Analytical Framework provides an overview of the PISA program, its unique aspects, and the frameworks for assessing reading, mathematics, science, financial literacy, global competence, and well-being. The framework outlines the purpose, structure, and content of the PISA 2018 assessments, including the domains assessed, the methods of evaluation, and the reporting of student performance. It also includes the context questionnaires and the collaborative nature of the project. The reading framework defines reading literacy, organizes the domain, and describes how reading literacy is assessed and reported. The mathematics framework defines mathematical literacy, explains how the domain is organized, and details the assessment methods. The science framework defines scientific literacy, outlines the domain organization, and describes the assessment process. The financial literacy framework defines financial literacy, explains how it is organized and assessed, and discusses the impact of other domains on financial literacy. The global competence framework highlights the importance of global competence assessment, describes how it is assessed, and provides conclusions. The questionnaire framework defines the core of the questionnaire, covers policy issues, and includes notes and references. The well-being framework provides an executive summary, defines well-being as a multi-dimensional construct, addresses measurement challenges, and suggests quality of life indicators. The framework also includes annexes with background questionnaires, expert groups, and possible topics for scenarios in the cognitive test.The PISA 2018 Assessment and Analytical Framework provides an overview of the PISA program, its unique aspects, and the frameworks for assessing reading, mathematics, science, financial literacy, global competence, and well-being.
