ELR2B2 is the aggregate used for Polytechnic Year 1 admissions. The letters stand for English Language, two relevant subjects and two best other subjects. From the 2028 intake, the structure changes to work with the new SEC and mixed G1/G2/G3 subject profiles.
The most important 2028 change is that one G2 subject can be used as one of the two ‘best’ subjects in the ELR2B2 aggregate. If a G3 subject is used in that G2-reference slot, it is mapped to G2 using SEAB’s official grade-mapping table.
MOE has also announced that the general Polytechnic Year 1 ELR2B2 cut-off will be adjusted from 26 to 22 points from the 2028 intake, while course-specific minimum entry requirements and competition still matter.
The Short Answer: What Does ELR2B2 Mean?
- EL = English Language.
- R2 = two relevant subjects for the Polytechnic course.
- B2 = two best other eligible subjects.
- From 2028, one of the B subjects can be taken at G2.
- The other core counted subjects remain at G3 under the published 2028 structure.
- The general cut-off is adjusted to 22 points from 2028.
The 2028 ELR2B2 Structure
MOE’s Full SBB admissions infographic shows the 2028 Polytechnic Year 1 aggregate as:
- English Language at G3;
- two relevant G3 subjects for the diploma applied for;
- one best G3 subject;
- one best G2 or G3 subject.
If the final best subject is taken at G3, it is mapped to G2 for that slot. This is why the general cut-off is recalibrated from 26 to 22 points.

Why the Cut-Off Changes From 26 to 22
The change is not a simple tightening of standards. It reflects the revised aggregate structure.
Because one of the two best-subject positions is counted at G2, the scoring scale changes. MOE therefore adjusts the general Polytechnic Year 1 threshold from 26 to 22.
Students still need to meet the relevant course’s minimum entry requirements, and competitive course outcomes can be much lower than the general eligibility threshold.
The G3-to-G2 Mapping Used for the G2 Slot
- G3 A1 to B3 → G2 Grade 1
- G3 B4 to C6 → G2 Grade 2
- G3 D7 → G2 Grade 3
- G3 E8 → G2 Grade 4
- G3 Grade 9 → G2 Grade 5
If the learner already has a G2 subject that is eligible for the final B slot, the original G2 grade can be used without mapping.
Relevant Subjects Depend on the Diploma
The R2 subjects are not the same for every Polytechnic course. Engineering, science, business, design, media and other diplomas can have different relevant-subject groups and minimum entry requirements.
This means two students with the same overall SEC grades can have different ELR2B2 scores for different diploma courses.
ELR2B2 is course-sensitive. Always calculate it for the specific diploma, not just once for the learner.
Minimum Entry Requirements Still Matter
A strong ELR2B2 aggregate does not override course-specific minimum entry requirements. A learner can have a competitive aggregate but still be ineligible if a required English, Mathematics, Science or other subject minimum is not met.
Families should therefore check two layers:
- General Polytechnic Year 1 aggregate eligibility.
- Course-specific minimum entry requirements.
Eligibility Is Not the Same as the Eventual Course Cut-Off
Historical course ranges are useful reference points, but they are not guaranteed future cut-offs. Actual posting outcomes depend on the cohort’s results, course choices and available places.
A learner who just meets the general 22-point threshold should therefore build a broad application list rather than assume access to every diploma.
How to Build a Polytechnic Application List
Aspirational Choices
Courses the learner genuinely wants and may reach with a stronger result or favourable competition.
Strong-Fit Choices
Courses where the learner’s aggregate, relevant subjects, interests and learning style align well.
Secure Choices
Courses the learner would still genuinely accept if the more competitive choices do not work out.
The purpose of secure choices is not to lower ambition. It is to avoid an application list where every option depends on the same optimistic assumption.
How Mathematics and Science Affect ELR2B2
For many engineering, computing and science-related diplomas, Mathematics and Science can be highly relevant to both the aggregate and minimum entry requirements.
A learner considering these pathways should protect conceptual depth in upper-secondary Mathematics and Science rather than optimising only for an aggregate.
How English Affects ELR2B2
English is the EL component and remains central. Course-specific minimum English requirements can also apply. A learner should therefore treat English as a core progression subject even when the intended diploma is technical.
ELR2B2 and SEC Grade Mapping
Grade mapping is a technical admissions tool. The learner’s SEC still records the original subject level and grade.
When a G3 subject is used in the G2-reference B slot, it is mapped according to SEAB’s official table. This does not mean the original G3 grade disappears.

A Parent ELR2B2 Checklist
- Identify the Polytechnic diploma.
- Find the correct ELR2B2 relevant-subject group for that diploma.
- Confirm English Language is at the required level.
- Identify the two relevant G3 subjects.
- Identify the best remaining G3 subject.
- Identify the best eligible G2 or G3 subject for the final slot.
- Map that final slot only when required.
- Check the 22-point general threshold for the 2028 structure.
- Check course-specific minimum entry requirements.
- Build aspirational, strong-fit and secure choices.
What Parents Should Avoid
- Do not calculate one ELR2B2 and assume it applies to every diploma.
- Do not ignore course-specific relevant subjects.
- Do not ignore minimum entry requirements.
- Do not confuse the general 22-point threshold with the eventual cut-off for a competitive course.
- Do not map every G3 subject to G2.
- Do not rely only on historical course ranges.
- Do not choose a diploma only because the aggregate fits.

- Options: build aspirational, strong-fit and secure baskets.
- Verification: check the official rules for the actual application year.
ELR2B2: A Course-Specific Admissions Tool
ELR2B2 is not a universal score that describes the learner. It is a Polytechnic admissions calculation built around English, relevant subjects and best other subjects.
From 2028, the SEC-era version recognises one G2 subject in the aggregate and recalibrates the general threshold to 22 points. The smartest use of that rule is to understand the learner’s real course options — not to reduce education to one number.
