PISA 2025 RESULTS (VOLUME I) – COUNTRY NOTES: BRUNEI DARUSSALAM © OECD 2026

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 student s for real life challenges and future success. Brunei Darussalam participated for the first time in PISA in 2018. By comparing results internationally, policy makers and educators in Brunei Darussalam can learn from other countries’ policies and practices.

Notes: Due to missing data, not all countries and economies are included in every dimension. F or each dimension, the top country/economy and the OECD average are highlighed; truancy values are sorted in descending order, so that values shown to the right correspond to lower levels of truancy.

For indicators derived from students’ and principals’ reports, differences between countries and economies should be interpre ted with caution, as they may reflect variations in response behaviour rather than true underlying differences. Non-response to questionnaires, cultural norms, as well as differing interpretations of questions can influence these indicators.

Definitions: Values that are not reported as percentages correspond to mean values of the corresponding questionnaire indices. Percentages are defined as follows: Percentage of students scoring above a baseline level of proficiency : students scoring at or above Level 2 in science, mathematics and reading; at or above Level 3 in computational problem solving; Growth mindset: Percentage of students who disagree or

Notes on data quality in PISA 2025 This edition of PISA includes data from 91 countries and economies. While t he vast majority of countries and economies met PISA’s technical standards, a small number did not. In particular, caution is required when interpreting results of countries and economies mentioned in this note with an asterisk () next to their names: their results could be affected by greater uncertainty, or even be biased, because one or more PISA sampling standards were not met. For more information, see the Reader’s Guide in PISA 2025 Results, Volume I and Chapter 18 (Data Adjudication) in the PISA 2025 Technical Report. In Brunei Darussalam, all data met the quality standards set by PISA and were con sidered fit for reporting. How well did 15-year-old students in Brunei Darussalam do on the test?

• Average 2025 results in Brunei Darussalam were lower than in 2022 in mathematics, a nd about the same as in 2022 in reading and science. • Compared to 2018, Brunei Darussalam saw significant improvements in both science and reading results (one of only few countries/economies where this was observed in PISA). • Over the most recent period (2022 to 2025), the gap between the highest-scorin g students (10% with the highest scores) and the weakest students (10% with the lowest scores) did not change significantly in mathematics and science, while it narrowed in reading. • Compared to 2018 the proportion of low-performing students (scoring below proficiency Level 2) decreased by three percentage points in mathematics; by nine percentage points in r eading; and by seven percentage points in science.

How does Brunei Darussalam compare? • Students in Brunei Darussalam scored less than the OECD average in mathematics, readin g and science (Figure 3).4  PISA 2025 RESULTS (VOLUME I) – COUNTRY NOTES: BRUNEI DARUSSALAM © OECD 2026

• A smaller proportion of students in Brunei Darussalam than on average across OECD countr ies were top performers (Level 5 or 6) in at least one subject. At the same time, a s maller proportion of students than on average across OECD countries achieved a minimum level of profi ciency

(Level 2 or higher) in all three subjects (Figure 4). • In computational problem solving, the mean score of students in Brunei Darussalam was lower than the OECD average (Figure 3). Figure 3.

What students know and can do in science Figure 4. Proficiency in science, mathematics and reading among 15-year-old students Brunei Darussalam and OECD average

Source: Tables I.B1.2a.10-12 • Some 61% of students in Brunei Darussalam 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. Over 85% of students in top performers B-S-J-Z (China), Mac ao

(China), Singapore, Estonia, Japan, Chinese Taipei and Korea (in descending order of that share) performed at this level or above. • In Brunei Darussalam, 2% 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 au tonomously apply their knowledge of and about science to a wide variety of situations, i ncluding unfamiliar ones.

ones. What students know and can do in mathematics • In Brunei Darussalam, 55% 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. c omparing the total distance across two alternative routes, or converting prices into a different currency). • Some 2% of students in Brunei Darussalam were top performers in mathematics, meaning that they attained Level 5 or 6 in the PISA mathematics test (OECD average: 8%). Th e largest shares of students attaining Level 5 or 6 were observed in Seven Asian countries and economies: B-S-JZ (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-solvi ng 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.6  PISA 2025 RESULTS (VOLUME I) – COUNTRY NOTES: BRUNEI DARUSSALAM © OECD 2026

What students know and can do in reading • Some 57% of students in Brunei Darussalam 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 Brunei Darussalam, 2% of students scored at Level 5 or higher in reading (OECD average: 6%).

minimum levels of proficiency in reading (Level 2 or higher) varied from 93% in B-S-J-Z (China) to 4% in Rwanda. • In Brunei Darussalam, 2% 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.

Notes: The left-hand chart shows how the performance of students at different levels of socio-economic status compares to the performance of students with similar socio-economic background across OECD countries on average. The shaded area represents a measure of uncertainty

(the 95% confidence interval). Percentages reported on the chart correspond to the perc entage of students in Brunei Darussalam that are in each international quartile of socio-economic status. The right-hand chart plots the performance and average socio-economic status of schools that participated in PISA (only schools with students in the modal grade for 15-year-olds are shown). Socio-economic disparities • 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 socioeconomic 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 Brunei Dar ussalam, 39% of students (the largest share) were in the top international quartile of the socio-econom ic scale, 7

meaning that they were among the most advantaged students who took the PISA test in 202 5. Their average score in science was 480 score points (Figure 5, left chart). In Singapore, Chinese Taipei and Macao (China), students of similar socio-economic background tend to score significantly higher. • The PISA index of economic, social and cultural status can also be used to or der 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 Brunei Darussalam socio-economically advant aged students (the top 25% in terms of socio-economic status) outperformed disadvantage d students (the bottom 25%) by 89 score points in science. This is similar to the average di fference between the two groups (85 score points) across OECD countries. • Between 2018 and 2025, the gap in science performance between the top and the bottom 25% of students in terms of socio-economic status narrowed in Brunei Darussalam, while the average gap across OECD countries remained stable. Over this period, performance improved among disadvantaged students, but remained stable among advantaged students. • Socio-economic status was a predictor of performance in science in all PISA-participating countries and economies. It accounted for 13% of the variation in science performance in PISA 2025 in Brunei Darussalam (compared to 12% on average across OECD countries). • Some 11% of disadvantaged students in Brunei Darussalam were able to score in the top qu arter of science performance. These students can be considered academically resilient because, despite their socio-economic disadvantage, they have attained educational excell ence 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.

of science performance. These students can be considered academically resilient because, despite their socio-economic disadvantage, they have attained educational excell ence 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. Student attitudes towards school and learning in Brunei Darussalam Student curiosity, perseverance and perceived value of school • In Brunei Darussalam, 77% of students agree or strongly agree that they are curious about many different things, compared to 73% across OECD countries. Moreover, 65% of students repor ted that they apply additional effort when work becomes challenging (OECD average 60%). At the same time, 12% agree or strongly agree that school has been a waste of time (OECD average: 24%). • Between 2022 and 2025, these attitudes changed somewhat in Brunei Darussalam. The share of students who reported being curious about many different things increased by 2.6 perc entage points; the proportion who reported applying additional effort when work becomes cha llenging increased by 4.6 percentage points; and the percentage of students who agreed that school had been a waste of time decreased by 4.2 percentage points during this period. • Curiosity, perseverance and valuing school are most often associated with higher science performance. In Brunei Darussalam, after accounting for students’ and schools’ socio -economic profile, a one-unit increase in the curiosity index is associated with a difference of 17 score points in science performance, compared to an average of 19 score points across OECD countries; a one-unit increase in the perseverance index is associated with a difference of 6 score poi nts in science performance (OECD average: 13 score points); students who perceive greater value in school and disagree that it is a waste of time tend to achieve higher scores in science (by 38 score points ) than their peers who feel they are wasting their time at school (OECD average: 27 score points).8 

Student attitudes towards learning • PISA 2025 also asked students about other attitudes towards learning. For example, 54 % of students in Brunei Darussalam have a growth mindset (OECD average: 69%), i.e. hold th e belief that intelligence can be cultivated through work, effort and feedback. On average across OE CD countries, students with a growth mindset score 28 score points higher in science than those with a fixed mindset. In Brunei Darussalam, this difference is 33 score points, after accounting for students’ and schools’ socio-economic profile. • PISA 2025 data further describe students’ self -regulation and goal-setting behaviours. For example, in Brunei Darussalam about 40% of students reported that they often or very often plan their approach to studying. Furthermore, 50% 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 clas smates for support with their schoolwork. In Brunei Darussalam, 87% of students ask their teachers for help when they need it and 94% ask their classmates when they do not fully understand someth ing (OECD averages: 77% and 82%, respectively). • In Brunei Darussalam help-seeking is positively related to science perform ance, after accounting for students’ and schools’ socio-economic profile. A one-unit increase in the index of help-seeking is associated with a difference of 6 score points (OECD average: 6 score points).

• In Brunei Darussalam help-seeking is positively related to science perform ance, after accounting for students’ and schools’ socio-economic profile. A one-unit increase in the index of help-seeking is associated with a difference of 6 score points (OECD average: 6 score points).

How is school life in Brunei Darussalam? Perceived shortages of human and material resources • In 2025, 23% of students in Brunei Darussalam 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 26% (OECD average: 39%). The prevalence of perceived teaching staff shortages in Brunei Darussa lam decreased compared to 2022 (45%). • PISA 2025 data reveal that perceived shortages of material resources remain a concern in most countries and economies. Some 23% of students in Brunei Darussalam attended schools whos e principals reported that a lack of educational material (e.g. textbooks, IT equipme nt, library or laboratory material) hindered instruction, at least to some extent, and 35% were in s chools 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 31% and 33%, respectively. Digital resources • In Brunei Darussalam, students reported spending on average 1.1 hours per day using d igital devices at school for learning activities (OECD average: 1.7 hours). At the sam e time, a nonnegligible share of students’ device use on school days is dedicated to non-learning activities: students in Brunei Darussalam reported spending 0.7 hours per day using digital devices at school for leisure (OECD average: 1.1 hours). • In Brunei Darussalam, 12% of students reported that their peers are often distracted by the use of

students in Brunei Darussalam reported spending 0.7 hours per day using digital devices at school for leisure (OECD average: 1.1 hours). • In Brunei Darussalam, 12% 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 sc ore 11 points lower 9

PISA 2025 RESULTS (VOLUME I) – COUNTRY NOTES: BRUNEI DARUSSALAM © OECD 2026

in science than those who reported no digital distraction (after accounting for students’ and schools’ socio-economic profile). In Brunei Darussalam they score 43 points lower. • In Brunei Darussalam, students in schools where cell phone use is not allowed on school premises are about 35% less likely to report digital distraction (OECD average: 13% less li kely). In 2025, 90% of students in Brunei Darussalam attended schools with such a ban (OECD average: 49%), up from PISA 2022 (81%; OECD average in PISA 2022: 34%). This indicates a substantial increase in the implementation of cell phone bans during this period. • Students in most education systems use AI chatbots for schoolwork, creating new challenges and opportunities for their learning. In Brunei Darussalam, 59% of students reported using AI chatbo ts 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 (Brunei Darussalam: 38%; OECD average: 31%) , to summarise a text they had to read (Brunei Darussalam: 36%; OECD average: 30%), and to draft text for writing assignments (Brunei Darussalam: 31%; OECD average: 29%).Only 6% of students reported never or almost never using AI chatbots for any of the schoolwork tasks examined in PISA (OECD average: 14%).

text for writing assignments (Brunei Darussalam: 31%; OECD average: 29%).Only 6% of students reported never or almost never using AI chatbots for any of the schoolwork tasks examined in PISA (OECD average: 14%). Bullying and cyberbullying • In Brunei Darussalam, 34% 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 incr eased between PISA 2022 and PISA 2025, as it did in a large majority of partic ipating countries and economies. This rise contrasts with the decline in bullying recorded in Brunei Darussalam between 2018 and 2022, which was likely linked to the lingering effects of COVID-19 disrupti ons. • Cyberbullying is relatively uncommon compared with other forms of bullying, but its victims tend to experience significant achievement deficits. In Brunei Darussalam, 5% 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%). These students scored, on average, 65 points lower in science than their peers. Teacher support and disciplinary climate in science lessons • In Brunei Darussalam, 75% of students reported that, in most science lessons, the teacher shows an interest in every student’s learning (OECD average: 69%), 82% that the teacher con tinues teaching until the students understand (OECD average: 66%), 85% that the teacher g ives extra help when students need it (OECD average: 73%). • Disciplinary climate in science lessons in 2025 remains a concern in many c ountries and economies: about 15% of students in Brunei Darussalam reported that they cannot work well in most or all lessons (OECD average: 19%); 28% reported noise and disorder disrupted most or every science lesson (OECD average: 31%); 16% of students reported that their classmates do

economies: about 15% of students in Brunei Darussalam reported that they cannot work well in most or all lessons (OECD average: 19%); 28% reported noise and disorder disrupted most or every science lesson (OECD average: 31%); 16% of students reported that their classmates do not listen to what the teacher says (OECD average: 29%). Parental involvement and support • 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 Brunei Darussalam . In 2025, 49% of students in Brunei Darussalam reported that their parents or guardians asked them, at least once per week, what they did at school , while 30% reported having at least weekly dis cussions about problems they might have at school. In 2022, the corresponding shares were 55% and 42%, respectively.10  PISA 2025 RESULTS (VOLUME I) – COUNTRY NOTES: BRUNEI DARUSSALAM © OECD 2026

Truancy and lateness • In 2025, around 29% of students in Brunei Darussalam reported having skipped at least one day of school in the two weeks prior to the test (OECD average: 22%); 16% reported skippi ng at least one class (OECD average: 24%); 45% reported arriving late for school (OECD average: 50%). In previous years, the corresponding shares were 8%, 11% and 44% (in 2022); 10%, 20% and 52% (in 2018). Student readiness for environmental challenges • In Brunei Darussalam, 63% of students reached at least baseline proficiency (Level 2) in environmental science. On average across OECD countries, 74% of students achi eve 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-environme ntal

environmental science. On average across OECD countries, 74% of students achi eve 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-environme ntal attitudes, although fewer feel confident about how to collaborate effectively. In Brunei Darussalam, 84% of students believe that they can positively impact the environment (OE CD average: 81%); 93% believe that collective action can address environmental problems (OECD average: 82%) ; 72% report knowing how to work with others to positively impact the environment (OECD average: 68%). • In Brunei Darussalam, 72% of students reported that they are somewhat or very interested i n 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 en vironment (Brunei Darussalam: 67%; OECD average: 56%) and making purchasing decisions based on the sustainability of products (OECD average: 54%; 59% in Brunei Darussalam). Key Features of PISA 2025 in Brunei Darussalam The content • 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 envi ronment. Results for science, mathematics, reading and computational problem solving are released on 8 Sept ember 2026 and analyses of students’ self-directed learning in 2027. The students • 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 Brunei Darussalam, 5 731 students, in 55 schools, completed the assessment, repres enting
