Programme for International Student Assessment

The Programme for International Student Assessment (PISA) is an OECD study that assesses how 15-year-old students apply reading, mathematics, and science knowledge in real-world contexts.

OECD: The Organisation for Economic Co-operation and Development is an intergovernmental organization that produces research and policy analysis. The OECD coordinates PISA and publishes its international results.
Education policy: The laws, priorities, and practices through which governments and institutions organize education. Governments use PISA comparisons when reviewing national education priorities.
Trends in International Mathematics and Science Study: An international study assessing mathematics and science achievement among students in grades four and eight. TIMSS emphasizes curriculum-related achievement at fixed grades, unlike PISA’s age-based applied-skills focus.
PISA shock: A public or political reaction to unexpectedly poor performance in a PISA assessment. The term describes how a PISA result can abruptly reshape national education debate.
Measurement invariance: The condition in which a measurement instrument represents the same construct comparably across groups. PISA comparisons require tasks and scales to function comparably across languages and cultures.
PISA assessment framework: The framework defining the knowledge, skills, and contexts assessed in a PISA cycle. It translates PISA’s aim of testing applied knowledge into subject-specific assessment designs.
PISA for Development: An OECD initiative adapting PISA tools to support assessment in low- and middle-income countries. It extends PISA’s approach to systems facing different assessment and data needs.
Progress in International Reading Literacy Study: An international study assessing reading literacy among students in the fourth year of schooling. PIRLS focuses on younger students’ reading, rather than PISA’s 15-year-olds and three core domains.
PISA league tables: Media and policy presentations that rank education systems using international assessment scores. PISA results often become league tables that simplify complex performance differences.
Cross-cultural validity: The extent to which an assessment measures the intended construct across cultural settings. Different contexts can affect how students interpret PISA tasks and demonstrate knowledge.
