WA1, WA2, EOY, prelims — what each assessment tells you (and why everyone still says SA1)
What are WA1, WA2 and EOY in Singapore primary schools?
Since MOE phased out mid-year exams for all primary levels by 2023, P3–P6 schools now run weighted assessments (WAs) — at most one per subject per term in Terms 1–3, usually WA1 then WA2 — plus one end-of-year exam (EOY) in Term 4. P6 sits prelims instead of a Term 3 WA, then PSLE.
| Term | What runs | Weight |
|---|---|---|
| Term 1–2 | WA1 | Modest, school-set |
| Term 3 (P4–P5) | WA2 | Modest, school-set |
| Term 3 (P6) | Prelims, in place of a Term 3 WA | Ungraded dress rehearsal — doesn't count toward the PSLE score |
| Term 4 | EOY examination ("SA2" in old money) | The year's main assessment |
- Weighted assessments (WAs) — at most one per subject per term in Terms 1–3, usually WA1 then WA2. Shorter than an exam, sat in class, each counting a modest share of the year's grade (the exact weighting is set by each school).
- One end-of-year examination (EOY) — Term 4, the main event. This is the paper most parents still call "SA2".
- P1–P2 have no weighted assessments or exams at all — teachers use ungraded checks instead.
- P6 is its own animal: prelims around Term 3, then PSLE. In 2026, PSLE written papers run 24–30 September (Mathematics Papers 1 and 2 on Friday, 25 September), per SEAB's published examination timetable, with results expected late November. Dates checked: 2026-09-26.
("SA1/SA2" survives in conversation, tuition-centre marketing and hand-me-down assessment books. Nothing wrong with the vocabulary — just know that "SA1" no longer corresponds to an actual mid-year exam in MOE schools.)
What does each result actually tell you?
WA1 (usually Term 1–2) is a smoke detector. Its weighting is small; its information value is not. A weak WA1 in a topic taught this term means the topic never landed — the cheapest possible time to fix it. The mistake is waiting to "see how the year goes": the syllabus won't revisit that topic, but the EOY will.
WA2 (Term 3) is the last cheap warning. By now the year's hardest content is mostly taught. A dip here, with a quarter of the year left, is a well-timed signal — enough runway to repair two or three topics properly (a calm plan for that).
The EOY measures the whole year — including what faded. This is the one that surprises parents: a child can genuinely master Term 1 content, get no review for six months, and lose it by November. That's not laziness; it's how memory works without spaced review. The EOY is as much a retention test as a learning test — prepare for it that way, by re-testing old topics cold, not just drilling current ones.
P6 prelims are a dress rehearsal, not a verdict. Schools often set prelims deliberately hard. The productive response to a prelim result is triage, not despair: sort the lost marks (concept, carelessness, time), fix the two biggest leaks, and re-test them before PSLE. There is enough time between prelims and late September to move a band — there is not enough time to fix everything, which is why specificity wins.
What's the takeaway across WA1, WA2 and the EOY?
Every assessment on this calendar answers the same two questions: which topics are weak now, and did previous fixes hold? Schools sample those answers a few times a year. A practice system can ask them continuously — Test Paper's free check-up maps every topic in about 15 minutes, and its weekly report tells you which repaired topics were re-tested and retained, so no WA or EOY ambushes you.
