Although the Map & Data Library is physically closed, we are still available remotely and happy to help. We can conduct consultations using online teleconferencing software. Please feel free to contact us at or use our help form. We have a number of tutorials available, are still supplying software licenses, and have compiled a list of resources for working with COVID-19 data.

Please note that our computer lab is also accessible for use through remote access. See this link for more information.

COVID-19: Updates on library services and operations

Programme for International Student Assessment (PISA)

PISA focuses on the assessment of student performance in reading, mathematics and science because they are foundational to a student's ongoing education. PISA also collects valuable information on student attitudes and motivations, and formally assesses skills such as collaborative problem solving and is investigating opportunities to assess other important competencies related, for example, to global competence.

Data creator: 

Organization for Economic Co-operation and Development (OECD)

Data type: 
Geographic coverage: 

International: Argentina, Australia, Austria, Azerbaijan, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hong Kong-China, Hungary, Iceland, Indonesia, Ireland, Israel, Italy, Japan, Jordan, Korea, Kyrgyz Republic, Latvia, Liechtenstein, Lithuania, Luxembourg, Macao-China, Mexico, The Netherlands, New Zealand, Norway, Poland, Portugal, Qatar, Republic of Montenegro, Republic of Serbia, Romania, Russian Federation, Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Chinese Taipei, Thailand, Tunisia, Turkey, United Kingdom, United States, Uruguay


Schools in each country are randomly selected by the international contractor for participation in PISA. At these schools, the test is given to students who are between age 15 years 3 months and age 16 years 2 months at the time of the test, rather than to students in a specific year of school. This average age of 15 was chosen because at this age young people in most OECD countries are nearing the end of compulsory education. The selection of schools and students is kept as inclusive as possible, so that the sample of students comes from a broad range of backgrounds and abilities.
