Full Subject-Based Banding Explained: What Woodlands Parents Need to Know Before 2027

If your child is currently in primary school or lower secondary, the way they will be assessed and placed in secondary school is fundamentally different from what you experienced as a student. Express, Normal Academic and Normal Technical are gone. In their place is a system called Full Subject-Based Banding, or Full SBB, and by 2027, the first cohort of students under this system will sit for a brand-new national examination.

For many Woodlands parents, this is confusing. The terminology is new. The pathways feel uncertain. And the advice from older parents no longer fully applies.

This guide breaks down everything you need to understand about Full Subject-Based Banding in Singapore, what it is, how it works, what the new G1, G2 and G3 levels mean, and most importantly, how it affects your child’s academic journey from PSLE through to secondary school graduation.

What Is Full Subject-Based Banding?

Full Subject-Based Banding is a system where secondary school students take each subject at a difficulty level that matches their individual ability, rather than being locked into a single academic stream for all subjects.

Under the old streaming system, a child who scored well enough at PSLE would enter the Express stream and take every subject at Express level, even subjects they were weaker in. A child posted to Normal Academic would take every subject at NA level, even subjects they excelled at. The system was rigid, and many educators and parents recognised that it did not reflect how children actually learn.

Full SBB fixes this by allowing a student to take, for example, English and Science at the most demanding level (G3) while taking Mathematics at a less demanding level (G2). The child is no longer labelled by a single stream. Instead, they are assessed subject by subject.

The Timeline

Full SBB did not appear overnight. Here is how it rolled out.

2020: MOE launched the Full SBB pilot in 28 secondary schools.

2021: The first cohort of Primary 6 students sat for the new PSLE AL scoring system, and the new Secondary 1 posting process was introduced.

2022 to 2024: Full SBB was progressively rolled out to all secondary schools across Singapore, reaching more than 120 schools by 2024.

2024: All Secondary 1 students entered secondary school under Full SBB. Streaming officially ended.

2027: The first cohort of Full SBB students will sit for the new Singapore-Cambridge Secondary Education Certificate (SEC) examination, replacing the existing O-Levels and N-Levels.

2028: The first cohort will be admitted to post-secondary institutions under revised admissions criteria.

If your child entered Secondary 1 in 2024 or later, they are fully under this new system. If your child is currently in primary school, this is the only system they will ever know.

Understanding G1, G2 and G3 Subject Levels

The letter G stands for General. The three levels replace what used to be the three streams.

G3 replaces the Express standard. This is the most academically demanding level. Students who take a subject at G3 are working at the same standard as the old Express stream for that subject.

G2 replaces the Normal Academic standard. This is the standard curriculum suited for the majority of students. It covers the same core content as G3 but at a slightly less demanding pace.

G1 replaces the Normal Technical standard. This is the foundational level, with more scaffolding and support to help students build a solid base of understanding.

The crucial difference from the old system is flexibility. Under Full SBB, a student’s subject level is not fixed. If a child starts Sec 1 taking Math at G2 but performs well, they can move up to G3 in subsequent years. The reverse is also possible. A child struggling at G3 can step down to G2 to build a stronger foundation before attempting the higher level again.

This flexibility is one of the biggest advantages of the new system. It means that a poor PSLE score does not permanently limit a child’s options the way the old streaming system sometimes did.

How PSLE Scores Determine Your Child’s Starting Point

When your child receives their PSLE results, they will be assigned to one of three Posting Groups. This determines which secondary schools they can apply to and the initial subject levels they start with in Sec 1.

PSLE Score 4 to 20: Posting Group 3. Your child will take all subjects at G3, the most demanding level.

PSLE Score 21 to 22: Posting Group 2 or 3. Parents and the student choose which Posting Group to apply through. All six school choices must use the same Posting Group.

PSLE Score 23 to 24: Posting Group 2. Your child will take most subjects at G2.

PSLE Score 25: Posting Group 1 or 2. Similar to the 21 to 22 band, there is a choice between two groups.

PSLE Score 26 to 30 (with at least AL7 in English and Math): Posting Group 1. Your child will take most subjects at G1.

Even if your child is posted through Posting Group 1 or 2, they can take individual subjects at a higher level if their PSLE Achievement Level for that specific subject was strong. For example, a child in Posting Group 2 who scored AL5 or better in English can take English at G3 from day one. A child who scored AL6 in a Standard subject, or AL A in a Foundation subject, can take that subject at G2.

This is why subject-specific performance at PSLE matters more than ever. Under the old system, your total aggregate score determined everything. Now, a child who performs exceptionally well in one subject can still access the most demanding level for that subject, regardless of their overall score.

What Are Mixed Form Classes?

Under Full SBB, your child will be placed in a mixed form class that includes students from different Posting Groups. This means their form classmates will have different academic strengths and will take subjects at different levels.

For common curriculum subjects such as Art, Design and Technology, Food and Consumer Education, Music, Physical Education and Character and Citizenship Education, all students learn together in these mixed classes. For academic subjects like English, Mathematics, Science and Mother Tongue, students are grouped with others taking the subject at the same G level.

The intention behind mixed form classes is to reduce the social stigma that came with being labelled Normal Technical or Normal Academic. Students build friendships across ability levels, and a child’s identity is no longer tied to a single stream label.

For parents, this means your child’s form class teacher may not be their subject teacher for every subject, and their closest friends may be taking some subjects at different levels. This is normal and intentional.

The New SEC Exam: What Replaces O-Levels and N-Levels

This is the change that affects your child’s future most directly. From 2027, the existing O-Level and N-Level examinations will be replaced by a single national examination called the Singapore-Cambridge Secondary Education Certificate, or SEC.

One Exam, Multiple Levels

All secondary school students will sit for the SEC examination at the same time. However, each subject will have different papers depending on whether the student is taking it at G1, G2 or G3. This is similar to how A-Level subjects have H1, H2 and H3 papers.

For example, a student taking Mathematics at G3 will receive a G3 Mathematics paper. A classmate taking Mathematics at G2 will receive a G2 paper on the same exam day. Both students sit in the same exam hall, but they are assessed at different standards.

One Certificate

Instead of receiving separate O-Level or N-Level certificates, every student will receive a single SEC certificate. This certificate will clearly list each subject the student took and the G level at which they were examined.

A student’s SEC certificate might show, for example, English Language (G3) with a grade of A1, Mathematics (G2) with a grade of A2, Science (G3) with a grade of B3, and Mother Tongue (G2) with a grade of B4. The mix of G levels is expected and normal under this system.

How This Affects Post-Secondary Pathways

From 2028, a new Post-Secondary Admissions Exercise (PSE) will replace the current separate admissions exercises for Junior Colleges, Polytechnics and ITE. Here is what each pathway requires.

Junior College entry requires strong G3 results. The current L1R5 computation, which stands for one language plus five relevant subjects, will transition to an L1R4 framework, but the principle remains the same. Students need G3 subjects to qualify for JC.

Polytechnic entry requires at least five G3 subjects under the current framework. From 2028, students may also be able to use one strong G2 subject in place of a G3 subject for their poly application, making this pathway slightly more accessible.

ITE entry remains available for students with G1 and G2 results, with expanded pathways including the Polytechnic Foundation Programme for eligible students.

The key takeaway for parents is that G3 subjects open the widest range of doors. While the new system is more flexible than the old one, students who want the most post-secondary options should aim to take as many subjects as possible at G3.

What This Means for Your Child’s Tuition Strategy

Full SBB changes how parents should think about academic support. Here are the practical implications.

Every Subject Matters Individually

Under the old system, parents sometimes focused on pulling up the overall aggregate. Under Full SBB, each subject determines its own G level independently. A child who is strong in English but weak in Math will take those subjects at different levels. This means targeted tuition for specific weak subjects is more important than ever.

PSLE Performance in Individual Subjects Has Long-Term Impact

Because PSLE Achievement Levels determine the starting G level for each subject, a child who scores AL5 in Science can start secondary school taking Science at G3, even if their overall PSLE score places them in Posting Group 2. This makes individual subject mastery at PSLE critical.

At BrightMinds, we see this playing out with our students every year. Parents who previously focused only on the total PSLE score are now paying closer attention to how their child performs in each subject, and adjusting their tuition support accordingly.

Moving Between Levels Is Possible But Not Automatic

While the system allows students to move up from G2 to G3 or step down, this is based on school performance and teacher recommendations. It is not guaranteed. A child who starts at G2 will need to consistently demonstrate strong understanding to be offered the chance to take the subject at G3. The best strategy is to build a strong foundation early rather than assume you can always move up later.

The First SEC Cohort Has No Seniors to Learn From

The students sitting for the SEC examination in 2027 will be the first cohort ever to take this exam. There are no past-year SEC papers to practise with. There are no senior students who can share their experience. This makes structured preparation and experienced guidance especially valuable.

Tuition centres that stay current with MOE syllabus changes, like BrightMinds, where our full-time tutors actively track curriculum updates, can help bridge this knowledge gap for families.

Common Questions from Woodlands Parents

Will universities recognise the SEC certificate?

MOE has confirmed that the SEC certificate is designed for seamless recognition by all local post-secondary institutions, including Junior Colleges, Polytechnics and ITE. G3 subjects are examined at the same standard as the current O-Levels, so academic rigour is maintained. For international universities, parents should verify recognition with specific institutions closer to 2027.

Can my child still stay back a fifth year?

Yes. The option to remain in secondary school for an additional year to take subjects at a more demanding level remains available for eligible students. This is particularly relevant for students who want to upgrade from G2 to G3 for specific subjects to improve their post-secondary options.

Does this affect IP (Integrated Programme) students?

No. Students in IP schools follow a six-year programme leading to the International Baccalaureate or A-Levels. They do not sit for the SEC examination. Full SBB primarily affects students in the O-Level and N-Level track, which is now the SEC track.

My child is in Primary 4. Should I be worried?

Not worried, but prepared. By the time your P4 child reaches secondary school, Full SBB will be well-established, and the SEC examination will have already been taken by at least one cohort. What you should focus on now is ensuring your child builds strong subject-specific foundations at PSLE, because their Achievement Level in each subject will directly determine which G level they start at in Sec 1.

How BrightMinds Helps Students Prepare for the New System

At BrightMinds Education in Woodlands, our full-time tutors have been tracking the Full SBB changes since they were first announced. Here is how we are helping students navigate the transition.

Subject-specific focus. Because each subject now has its own G level, we work with parents to identify which subjects need the most support and prioritise accordingly. A child aiming to take Science at G3 in secondary school needs to achieve at least AL5 in Science at PSLE, and our PSLE Science programme is designed to make that achievable.

PSLE AL score targeting. Our tutors help parents set realistic, subject-by-subject AL targets rather than just chasing an overall score. This is a more strategic approach under the new system.

Secondary preparation. For our secondary students, we ensure lesson content aligns with the G level they are studying at. A student taking G3 Math receives different support from a student building foundations at G2, and we structure our small-group classes accordingly.

Staying current. Our worksheets are updated weekly to reflect the latest MOE syllabus requirements. As the SEC exam format becomes clearer, we will incorporate SEC-specific preparation into our programmes.

The Bottom Line for Parents

Full Subject-Based Banding is not something to fear. It is a genuinely more flexible system that recognises what most parents already know: children are not equally strong in every subject, and they should not be forced into a single box.

But flexibility also means more decisions. You now need to think about your child’s education subject by subject, not stream by stream. You need to understand what G levels your child is working at, what is required to move up, and what post-secondary pathways different G-level combinations open up.

The families who navigate this system best are the ones who understand it early and plan accordingly. If you have questions about how Full SBB affects your child, whether they are in primary school preparing for PSLE or already in secondary school, we are here to help.
