PISA 2025 Results (Volume I): Chinese Taipei

The Programme for International Student Assessment (PISA) assesses the knowledge, skills and attitudes of 15-year-old students. The tests explore how well students can solve complex problems, think critically and communicate effectively; data collected through questionnaires describe the context in which students learn. This gives insights into how well education systems are preparing students for real life challenges and future success. Chinese Taipei participated for the first time in PISA in 2006. By comparing results internationally, policy makers and educators in Chinese Taipei can learn from other countries’ policies and practices.

• Average 2025 results in Chinese Taipei were about the same as in 2022 in mathematics, reading and science.

• When considering all results observed in PISA over 20 years (2006-2025), the 2022 results are among the highest ever measured by PISA in science. In mathematics and reading, results fluctuated somewhat over this period, with no clear direction, and are close to the historic average in 2025.

• Over the most recent period (2022 to 2025), the gap between the highest-scoring students (10% with the highest scores) and the weakest students (10% with the lowest scores) did not change significantly in mathematics, reading and science.

• Compared to 2015 the proportion of low-performing students (scoring below proficiency Level 2) did not change significantly in mathematics, reading and science.

• Students in Chinese Taipei scored higher than the OECD average in mathematics, reading and science (Figure 3).

• More students in Chinese Taipei than on average across OECD countries were top performers (Level 5 or 6) in at least one subject. At the same time, a larger proportion of students than on average across OECD countries achieved a minimum level of proficiency (Level 2 or higher) in all three subjects (Figure 4).

• In computational problem solving, the mean score of students in Chinese Taipei was higher than the OECD average (Figure 3).

• Some 87% of students in Chinese Taipei attained Level 2 or higher in science (OECD average: 74%). At a minimum, these students can recognize 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.

• In Chinese Taipei, 20% of students were top performers in science, meaning that they were proficient at Level 5 or 6 (OECD average: 7%). These students can creatively and autonomously apply their knowledge of and about science to a wide variety of situations, including unfamiliar ones.

• In Chinese Taipei, 85% of students attained at least Level 2 proficiency in mathematics (OECD average: 65%). At a minimum, these students can interpret and recognize, 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).

• Some 32% of students in Chinese Taipei were top performers in mathematics, meaning that they attained Level 5 or 6 in the PISA mathematics test (OECD average: 8%). The largest shares of students attaining Level 5 or 6 were observed in Seven Asian countries and economies: B-S-J-Z (China) (54%), Singapore (37%), Chinese Taipei (32%), Macao (China) (29%), Korea (23%), Japan (22%) and Hong Kong (China) (21%). At these levels, students can model complex situations mathematically, and can select, compare and evaluate appropriate problem-solving strategies for dealing with them. In 13 countries and economies participating in PISA 2025, more than 10% of students attained Level 5 or 6 proficiency.

• Some 82% of students in Chinese Taipei attained Level 2 or higher in reading (OECD average: 69%). At a minimum, these students can identify the main idea in a text of moderate length, find information based on explicit, though sometimes complex criteria, and can reflect on the purpose and form of texts when explicitly directed to do so. The share of 15-year-old students who attained minimum levels of proficiency in reading (Level 2 or higher) varied from 93% in B-S-J-Z (China) to 4% in Rwanda.

• In Chinese Taipei, 13% of students scored at Level 5 or higher in reading (OECD average: 6%). These students can 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.

• The PISA index of economic, social and cultural status is computed in such a way that all students taking the PISA test, regardless of the country where they live, can be placed on the same socio-economic scale. This means that it is possible to use this index to compare the performance of students of similar socio-economic background in different countries. In Chinese Taipei, 41% of students (the largest share) were in the top international quartile of the socio-economic scale, meaning that they were among the most advantaged students who took the PISA test in 2025. Their average score in science was 578 score points (Figure 5, left chart); one of the highest for students of similar socio-economic background.

• The PISA index of economic, social and cultural status can also be used to order students from the most disadvantaged to the most advantaged within each country and economy, and to create four groups of students of equal size (each comprising 25% of the population of 15-year-old students in each country/economy). In Chinese Taipei socio-economically advantaged students (the top 25% in terms of socio-economic status) outperformed disadvantaged students (the bottom 25%) by 91 score points in science. This is similar to the average difference between the two groups (85 score points) across OECD countries.

• Between 2015 and 2025, the gap in science performance between the top and the bottom 25% of students in terms of socio-economic status remained stable in Chinese Taipei, while the average gap across OECD countries narrowed. Over this period, performance remained stable both among advantaged and disadvantaged students.

• Socio-economic status was a predictor of performance in science in all PISA-participating countries and economies. It accounted for 11% of the variation in science performance in PISA 2025 in Chinese Taipei (compared to 12% on average across OECD countries).

• Some 11% of disadvantaged students in Chinese Taipei were able to score in the top quarter of science performance. These students can be considered academically resilient because, despite their socio-economic disadvantage, they have attained educational excellence by comparison with students in their own country. On average across OECD countries, 12% of disadvantaged students scored in the top quarter of science performance in their own countries.

• In Chinese Taipei, 73% of students agree or strongly agree that they are curious about many different things, compared to 73% across OECD countries. Moreover, 69% of students reported that they apply additional effort when work becomes challenging (OECD average 60%). At the same time, 21% agree or strongly agree that school has been a waste of time (OECD average: 24%).

• Between 2022 and 2025, these attitudes changed somewhat in Chinese Taipei. The share of students who reported being curious about many different things decreased by 4.6 percentage points; the proportion who reported applying additional effort when work becomes challenging remained stable; and the percentage of students who agreed that school had been a waste of time increased by 2.6 percentage points during this period.

• Curiosity, perseverance and valuing school are most often associated with higher science performance. In Chinese Taipei, after accounting for students’ and schools’ socio-economic profile, a one-unit increase in the curiosity index is associated with a difference of 11 score points in science performance, compared to an average of 19 score points across OECD countries; students who perceive greater value in school and disagree that it is a waste of time tend to achieve higher scores in science (by 25 score points ) than their peers who feel they are wasting their time at school (OECD average: 27 score points).

• PISA 2025 also asked students about other attitudes towards learning. For example, 46% of students in Chinese Taipei have a growth mindset (OECD average: 69%), i.e. hold the belief that intelligence can be cultivated through work, effort and feedback. On average across OECD countries, students with a growth mindset score 28 score points higher in science than those with a fixed mindset. In Chinese Taipei, this difference is not significant.

• PISA 2025 data show that there is still room for improvement in terms of students’ self-regulation and goal-setting behaviours. For example, only about 30% of students in Chinese Taipei report that they often or very often plan their approach to studying. Furthermore, 33% of students ask themselves questions about the material to check if they have understood everything (OECD averages: 37% and 49%, respectively).

• An autonomous self-regulated learner knows when and where to ask for help. PISA 2025 data show that, in most countries, students tend to rely on their teachers and classmates for support with their schoolwork. In Chinese Taipei, 83% of students ask their teachers for help when they need it and 90% ask their classmates when they do not fully understand something (OECD averages: 77% and 82%, respectively).

• In Chinese Taipei self-regulated goal-setting and help-seeking are positively related to science performance, after accounting for students’ and schools’ socio-economic profile. A one-unit increase in the index of goal-setting is associated with a difference of 9 score points (OECD average: 3 score points).A one-unit increase in the index of help-seeking is associated with a difference of 13 score points (OECD average: 6 score points).

• In 2025, 28% of students in Chinese Taipei were in schools whose principals reported that instruction was hindered, at least to some extent, by a perceived lack of teaching staff (OECD average: 39%); the corresponding share for a perceived lack of assisting staff was 20% (OECD average: 39%). The prevalence of perceived teaching staff shortages in Chinese Taipei did not change significantly compared to 2022.

• PISA 2025 data reveal that perceived shortages of material resources remain a concern in most countries and economies. Some 7% of students in Chinese Taipei attended schools whose principals reported that a lack of educational material (e.g. textbooks, IT equipment, library or laboratory material) hindered instruction, at least to some extent, and 8% were in schools where a lack of physical infrastructure (e.g. buildings, grounds, heating/cooling systems, lighting and acoustic systems) was perceived to hinder instruction. In 2022, the corresponding shares were 6% and 19%, respectively.

• In Chinese Taipei, students reported spending on average 1.8 hours per day using digital devices at school for learning activities (OECD average: 1.7 hours). At the same time, a non-negligible share of students’ device use on school days is dedicated to non-learning activities: students in Chinese Taipei reported spending 1.1 hours per day using digital devices at school for leisure (OECD average: 1.1 hours).

• In Chinese Taipei, 13% of students reported that their peers are often distracted by the use of digital devices during most or all science lessons (OECD average: 28%). On average across OECD countries, students who reported digital distraction in their science classes score 11 points lower in science than those who reported no digital distraction (after accounting for students’ and schools’ socio-economic profile). Chinese Taipei is among the minority of countries and economies in which digital distraction is not associated with significant differences in student performance.

• In Chinese Taipei, students in schools where cell phone use is not allowed on school premises are about 54% less likely to report digital distraction (OECD average: 13% less likely). In 2025, 43% of students in Chinese Taipei attended schools with such a ban (OECD average: 49%), close to the level observed in PISA 2022 (46%; OECD average in PISA 2022: 34%).

• Students in most education systems use AI chatbots for schoolwork, creating new challenges and opportunities for their learning. In Chinese Taipei, 40% of students reported using AI chatbots to help them learn at least once a week (OECD average: 46%). Students also frequently use AI to conduct preliminary research on a new topic (Chinese Taipei: 22%; OECD average: 31%), to summarise a text they had to read (Chinese Taipei: 20%; OECD average: 30%), and to draft text for writing assignments (Chinese Taipei: 21%; OECD average: 29%).Only 16% of students reported never or almost never using AI chatbots for any of the schoolwork tasks examined in PISA (OECD average: 14%).

• In Chinese Taipei, 11% of students reported being victims of at least one form of bullying a few times per month or more in 2025 (OECD average: 20%). The prevalence of bullying increased between PISA 2022 and PISA 2025, as it did in a large majority of participating countries and economies. This rise contrasts with the decline in bullying recorded in Chinese Taipei between 2018 and 2022, which was likely linked to the lingering effects of COVID-19 disruptions.

• Cyberbullying is relatively uncommon compared with other forms of bullying. In Chinese Taipei, 2% of students reported that upsetting information about them was published online, without their consent, at least a few times a month during the 12 months prior to the PISA test (OECD average: 3%).

• In Chinese Taipei, 79% of students reported that, in most science lessons, the teacher shows an interest in every student’s learning (OECD average: 69%), 72% that the teacher continues teaching until the students understand (OECD average: 66%), 84% that the teacher gives extra help when students need it (OECD average: 73%). In 2015, the corresponding shares were 57%, 67% and 79%.

• Disciplinary climate in science lessons in 2025 remains a concern in many countries and economies: about 13% of students in Chinese Taipei reported that they cannot work well in most or all lessons (OECD average: 19%); 16% reported noise and disorder disrupted most or every science lesson (OECD average: 31%); 11% of students reported that their classmates do not listen to what the teacher says (OECD average: 29%).

• Disciplinary climate and teacher support in science lessons improved between 2015 and 2025 on average across OECD countries. This was also the case in Chinese Taipei. Countries and economies with an improved disciplinary climate tend to show stability or an increase in their average science performance compared to 2015.

• Student reports of family support substantially decreased in almost all PISA-participating countries and economies between 2022 and 2025. This was also the case in Chinese Taipei. In 2025, 59% of students in Chinese Taipei reported that their parents or guardians asked them, at least once per week, what they did at school , while 53% reported having at least weekly discussions about problems they might have at school. In 2022, the corresponding shares were 62% and 58%, respectively.

• In 2025, around 3% of students in Chinese Taipei reported having skipped at least one day of school in the two weeks prior to the test (OECD average: 22%); 10% reported skipping at least one class (OECD average: 24%); 38% reported arriving late for school (OECD average: 50%). In previous years, the corresponding shares were 2%, 10% and 34% (in 2022); 5%, 13% and 38% (in 2018).

• In Chinese Taipei, 87% of students reached at least baseline proficiency (Level 2) in environmental science. On average across OECD countries, 74% of students achieve this level, with more than 85% reaching it in seven countries and economies.

• PISA 2025 shows that students in most education systems report strong pro-environmental attitudes, although fewer feel confident about how to collaborate effectively. In Chinese Taipei, 92% of students believe that they can positively impact the environment (OECD average: 81%); 87% believe that collective action can address environmental problems (OECD average: 82%); 86% report knowing how to work with others to positively impact the environment (OECD average: 68%).

• In Chinese Taipei, 50% of students reported that they are somewhat or very interested in contributing to protecting the environment in their future jobs (OECD average: 62%).

• Most students engaged in environment-related activities at least once over the 12 months prior to the PISA test. On average across OECD countries, the most common forms of engagement are discussing with friends and family how to have a positive impact on the environment (Chinese Taipei: 53%; OECD average: 56%) and making purchasing decisions based on the sustainability of products (OECD average: 54%; 53% in Chinese Taipei).

• The PISA 2025 survey focused on science, with mathematics and reading as minor areas; an assessment of learning in the digital world measured students’ computational problem-solving skills and their ability to self-direct their learning in a digital environment. PISA 2025 also included an assessment of young people’s communicative skills in English, which was optional and available only for countries and economies where English is a foreign language; Chinese Taipei participated in this assessment. Results for science, mathematics, reading and computational problem solving are released on 8 September 2026; results for English as a foreign language and analyses of students’ self-directed learning in 2027.

• Over 760 000 students took the assessment in 2025, representing about 33 million 15-year-olds in the schools of the 91 participating countries and economies.

• In Chinese Taipei, 7 279 students, in 292 schools, completed the assessment, representing about 181 000 15-year-old students (an estimated 92% of the total population of 15-year-olds). An additional sample of students, from the same schools, completed the assessment of English as a foreign language.

• PISA students are aged between 15 years 3 months and 16 years 2 months at the time of the assessment, and they have completed at least 6 years of formal schooling. In this note, they are referred to as 15-year-old students.

• Students took a two hour test, and each student was tested in two subjects. Different students were given different test questions and different combinations of subjects (e.g. science followed by reading, or mathematics followed by science, etc.). Test items were a mixture of multiple-choice questions and questions requiring students to construct their own responses.

• Students also answered a background questionnaire, which took about 35 minutes to complete. The questionnaire sought information about the students themselves, their attitudes, dispositions and beliefs, their homes, and their school and learning experiences. School principals completed a questionnaire about school management, organisation, and the learning environment.

• Some countries/economies also distributed additional questionnaires, to students, parents and/or teachers, to elicit more information. The findings from these optional questionnaires are not covered by this note.
