Whether you’re a student finishing Primary 4 or a parent keeping an eye on PSLE results and Secondary 1 posting groups, it’s important to understand how the Subject-Based Banding (SBB) system works. Introduced by the Ministry of Education (MOE) in 2024, SBB lets students take subjects at levels that suit their strengths, rather than placing all students in a uniform class structure.
In this guide, we’ll explain how SBB works, what it means for placement and subject choices, and how to navigate it for the best start in secondary school.
Subject-Based Banding (SBB) was introduced to replace the GCE O Level exams and the Express, Normal Academic (N(A)), Normal Technical (N(T)) streaming system.
With this new system, MOE aims to create a more flexible, inclusive, and personalised learning environment where students can excel in subjects they are strong in while receiving support in areas they find challenging1.
In primary school, SBB begins with differentiated levels in core subjects, typically starting in Primary 4 with Foundation and Standard levels. This helps identify students’ strengths early and prepares them for the transition to secondary school.
In secondary school, Full SBB is implemented, allowing students to take each subject at the level that best matches their abilities, interests, and learning needs, regardless of their class placement. Secondary students are also placed in mixed-form classes, which promote an inclusive learning environment and help them build confidence and academic skills while learning at their own pace.
Subject-Based Banding (SBB) starts to take effect toward the end of Primary 4, later influencing Secondary 1 posting and banding.
At Primary 4, students will begin to encounter differentiated levels in core subjects like English, Mathematics, and Science.
Those who need extra support may continue at the Foundation level, focusing on building strong fundamentals, while students who are ready for more challenging work can take subjects at the Standard level, which allows them to explore advanced content and apply concepts in greater depth.
This early differentiation helps teachers tailor instruction more effectively. It also gives students a clearer sense of their strengths and areas for improvement before they transition to secondary school.
When students move to Secondary 1, they are placed into posting groups based on their PSLE scores and learning profiles.
Throughout lower secondary, students will follow a common curriculum syllabus, which forms the basic academic foundation for their upper secondary journey. These subjects include mother tongue languages, English language, Science, Mathematics, and more.
For each subject, students will be assigned a different subject level, allowing every child to study at a pace that suits them best:
Students are also placed in mixed-form classes, meaning students will take subjects at different levels in the same class. This environment encourages collaboration, as students can support one another and benefit from different perspectives.
At the same time, teachers adapt lessons to accommodate the range of abilities, ensuring that every student receives both the challenge and guidance they need to succeed in each subject.
At the end of primary school, students take the Primary School Leaving Examination (PSLE). Under SBB, PSLE results are used not just for overall ranking, but also to identify strengths in each subject, which helps schools place students into suitable Secondary 1 posting groups.
Here is how students’ PSLE exam results will be translated into posting groups and subject levels2:

Under the Full SBB system, Secondary 1 students will start taking each subject with different subject levels (G1, G2, and G3).
In Secondary 2, schools will expand subject options, allowing students to adjust their subject levels based on performance and interest. For example, students interested in humanities subjects such as Geography, History, or Literature may move to a higher level (G3) to explore content in greater depth.
By Secondary 4 or 5, each batch of students will usually confirm their subject combinations and sit for the Singapore-Cambridge Secondary Education Certificate (SEC). The Full SBB system will replace the GCE O-Level examination and the old Express, N(A), and N(T) streams starting from 20273.
Here is a quick breakdown of the scoring system for each subject level and their passing grades4:
Students’ SEC grades can be aggregated for post-secondary pathways, such as the L1R5 for Junior Colleges (JCs) and the ELMAB3 for the Polytechnic Foundation Programme.
After completing secondary school and receiving their Singapore-Cambridge Secondary Education Certificate (SEC) results, students can choose from several post-secondary pathways depending on their academic strengths, interests, and career goals.
Each pathway offers different learning styles and progression routes, allowing students to continue developing their skills in ways that suit them best. Common post-secondary options include:
JC is a two-year programme that prepares students for the A-Level examinations and provides a strong academic foundation for university studies.
A three-year pre-university programme that prepares students for the A-Level examinations, offering a slightly longer and more paced academic route compared to Junior Colleges.
Polytechnic courses typically last three years and can lead directly to employment or further studies at university.
ITE programmes provide practical training and can also serve as a pathway to polytechnic education.
Best for: Students who enjoy hands-on learning and want to develop technical or vocational skills in areas such as engineering, hospitality, or digital technology.
Subject-Based Banding allows students to study each subject at a level that matches their abilities, helping them learn more effectively and progress at their own pace. Here are some of the benefits of the SBB system.
By placing students from different posting groups in the same classes, SBB encourages interaction among peers with different academic strengths and learning styles. This helps reduce the sense of division that existed under the old streaming system and allows students to learn from one another, creating a more collaborative and supportive learning environment.
SBB allows students to take each subject at the level that best suits their abilities. This means students can challenge themselves in subjects they excel in while receiving additional support in areas they find more difficult.
Studying subjects at an appropriate level helps students better understand concepts and keep up with the curriculum. This can improve engagement in class and help students build confidence in their academic abilities over time.
Because students can take higher-level subjects in their areas of strength, they may still qualify for different post-secondary options such as junior colleges, polytechnics, or the Institute of Technical Education. This flexibility helps ensure that students are not limited by a single overall academic stream.
At Zenith Education Studio, students are equipped with the knowledge, skills, and confidence needed to thrive regardless of any new changes to the education system.
