The OECD Programme for International Student Assessment (PISA) examines what students know in reading, mathematics and science, and what they can do with what they know. It provides the most comprehensive and rigorous international assessment of student learning outcomes to date. Results from PISA indicate the quality and equity of learning outcomes attained around the world, and allow educators and policy makers to learn from the policies and practices applied in other countries. This is one of six volumes that present the results of the PISA 2018 survey, the seventh round of the triennial assessment. Volume I, What Students Know and Can Do, provides a detailed examination of student performance in reading, mathematics and science, and describes how performance has changed since previous PISA assessments.
PISA 2018 Results (Volume I)
Abstract
Executive Summary
Reading proficiency is essential for a wide variety of human activities – from following instructions in a manual; to finding out the who, what, when, where and why of an event; to communicating with others for a specific purpose or transaction. PISA recognises that evolving technologies have changed the ways people read and exchange information, whether at home, at school or in the workplace. Digitalisation has resulted in the emergence and availability of new forms of text, ranging from the concise (text messages; annotated search-engine results) to the lengthy (tabbed, multipage websites; newly accessible archival material scanned from microfiches). In response, education systems are increasingly incorporating digital (reading) literacy into their programmes of instruction.
Reading was the main subject assessed in PISA 2018. The PISA 2018 reading assessment, which was delivered on computer in most of the 79 countries and economies that participated, included new text and assessment formats made possible through digital delivery. The test aimed to assess reading literacy in the digital environment while retaining the ability to measure trends in reading literacy over the past two decades. PISA 2018 defined reading literacy as understanding, using, evaluating, reflecting on and engaging with texts in order to achieve one’s goals, to develop one’s knowledge and potential, and to participate in society.
What students know and can do: main findings
In reading
-
Beijing, Shanghai, Jiangsu and Zhejiang (China) and Singapore scored significantly higher in reading than all other countries/ economies that participated in PISA 2018. Estonia, Canada, Finland and Ireland were the highest-performing OECD countries in reading.
-
Some 77 % of students, on average across OECD countries, attained at least Level 2 proficiency in reading. At a minimum, these students are able to identify the main idea in a text of moderate length, find information based on explicit, though sometimes complex, criteria, and reflect on the purpose and form of texts when explicitly directed to do so. Over 85 % of students in Beijing, Shanghai, Jiangsu and Zhejiang (China), Canada, Estonia, Finland, Hong Kong (China), Ireland, Macao (China), Poland and Singapore performed at this level or above.
-
Around 8.7 % of students, on average across OECD countries, were top performers in reading, meaning that they attained Level 5 or 6 in the PISA reading test. At these levels, students are able to comprehend lengthy texts, deal with concepts that are abstract or counterintuitive, and establish distinctions between fact and opinion, based on implicit cues pertaining to the content or source of the information. In 20 education systems, including those of 15 OECD countries, over 10 % of 15-year-old students were top performers.
In mathematics and science
-
On average across OECD countries, 76 % of students attained Level 2 or higher in mathematics. At a minimum, these students can interpret and recognise, without direct instructions, how a (simple) situation can be represented mathematically (e.g. comparing the total distance across two alternative routes, or converting prices into a different currency). However, in 24 countries and economies, more than 50 % of students scored below this level of proficiency.
-
Around one in six 15-year-old students in Beijing, Shanghai, Jiangsu and Zhejiang (China) (16.5 %), and about one in seven students in Singapore (13.8 %), scored at Level 6 in mathematics, the highest level of proficiency that PISA describes. These students are capable of advanced mathematical thinking and reasoning. On average across OECD countries, only 2.4 % of students scored at this level.
-
On average across OECD countries, 78 % of students attained Level 2 or higher in science. At a minimum, these students can recognise the correct explanation for familiar scientific phenomena and can use such knowledge to identify, in simple cases, whether a conclusion is valid based on the data provided. More than 90 % of students in Beijing, Shanghai, Jiangsu and Zhejiang (China) (97.9 %), Macao (China) (94.0 %), Estonia (91.2 %) and Singapore (91.0 %) achieved this benchmark.
Trends in performance
-
On average across OECD countries, mean performance in reading, mathematics and science remained stable between 2015 and 2018.
-
There were large differences between individual countries and economies in how their performance changed between 2015 and 2018. For example, mean performance in mathematics improved in 13 countries/economies (Albania, Iceland, Jordan, Latvia, Macao [China], Montenegro, Peru, Poland, Qatar, the Republic of North Macedonia, the Slovak Republic, Turkey and the United Kingdom), declined in 3 countries/economies (Malta, Romania and Chinese Taipei), and remained stable in the remaining 47 participating countries/economies.
-
Seven countries/economies saw improvements, on average, in the reading, mathematics and science performance of their students throughout their participation in PISA: Albania, Colombia, Macao (China), the Republic of Moldova, Peru, Portugal and Qatar. Seven countries saw declining mean performance across all three subjects: Australia, Finland, Iceland, Korea, the Netherlands, New Zealand and the Slovak Republic.
-
Between 2003 and 2018, Brazil, Indonesia, Mexico, Turkey and Uruguay enrolled many more 15-year-olds in secondary education without sacrificing the quality of the education provided.
Around the world, the share of 15-year-old students, in grade 7 and above, who reached a minimum level of proficiency in reading (at least Level 2 on the PISA scale) ranged from close to 90 % in Beijing, Shanghai, Jiangsu and Zhejiang (China), Estonia, Macao (China) and Singapore, to less than 10 % in Cambodia, Senegal and Zambia (countries that participated in the PISA for Development assessment in 2017). The share of 15-year-old students who attained minimum levels of proficiency in mathematics (at least Level 2) varied even more – between 98 % in Beijing, Shanghai, Jiangsu and Zhejiang (China) and 2 % in Zambia. On average across OECD countries, around one in four 15-year-olds did not attain a minimum level of proficiency in reading or mathematics. These numbers show that all countries still have some way to go towards reaching the global goals for quality education, as defined in the UN Sustainable Development Goal for education, by 2030.

Long-term trends are reported for the longest available period since PISA 2000 for reading, PISA 2003 for mathematics and PISA 2006 for science.
Results based on reading performance are reported as missing for Spain (see Annex A9). The OECD average does not include Spain in these cases.
Countries and economies are ranked in descending order of the mean reading score in PISA 2018.
