WA1, WA2, EOY, prelims — what each assessment tells you (and why everyone still says SA1)

Facts and prices last verified: 2026-08-05. Corrections: support@test-paper.info.

If you sat PSLE yourself, the exam calendar you remember — CA1, SA1, CA2, SA2 — no longer exists. MOE removed mid-year examinations for all primary levels (phased out from 2019, fully by 2023) to cut assessment load. What schools run now, for P3–P6:

• Weighted assessments (WAs) — at most one per subject per term in Terms 1–3. 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, with results expected late November.

("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 each result is actually for

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.

The through-line

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.
