AEIS Complete Guide 2026: Timeline, Test, and Real Costs

A father in Shenzhen emailed me last March. His daughter had been preparing for AEIS for eight months with a tutor in Beijing, scoring 82% on practice papers. She sat the September exam. She didn't get a place. The reason wasn't her English or maths — it was that nobody had told the family AEIS doesn't guarantee a school even if you pass, and that the practice papers her tutor used were from 2018.

This AEIS complete guide is written for families like his. Not the glossy overview version. The version where I tell you what actually happens between deciding to move to Singapore and your child walking into a local school in January 2027.

What AEIS actually is in 2026 (and what it isn't)

AEIS — Admissions Exercise for International Students — is the centralised test the Ministry of Education uses to place foreign-passport students into Primary 2 to 5 and Secondary 1 to 3 in Singapore government and government-aided schools. It runs once a year, in September/October, with results released around late December.

Three things parents consistently misunderstand:

1. AEIS is a placement test, not a pass/fail exam. MOE doesn't publish a "pass mark." They rank candidates and offer places based on availability in schools near your residential address — meaning a strong score in a year with few vacancies near your home can still result in no offer.

2. You don't choose the school. You can indicate preferred zones, but final allocation is MOE's call. Families who set their heart on a specific brand-name school often end up disappointed.

3. AEIS only tests English and Mathematics. Not Chinese, not Science, not general knowledge. But the English paper is harder than most overseas families expect, and the maths paper uses Singapore's curriculum framing — bar models, heuristic problem-solving — which feels alien to students from China, India, or international school backgrounds.

If your child misses the September window or doesn't get a place, there's S-AEIS in February — same format, fewer seats, and only for entry into P2/P3/P4 and Sec 1/Sec 2.

The 2026 AEIS timeline you should print and tape to the fridge

The single most useful thing I can give you is dates. MOE publishes the official calendar around June each year — always check moe.gov.sg for confirmation, but the rhythm is consistent year-on-year.

The trap most families fall into: they treat July registration as the start. By July, you should already have completed at least three months of preparation. Singapore-style English comprehension and Singapore-style maths heuristics are not picked up in eight weeks, no matter what a marketing brochure tells you.

For the document side of registration, I've written a separate piece that goes paper by paper — see the AEIS Registration Document Checklist 2026: What Overseas Families Actually Need. Don't underestimate this. Last year I watched a family lose their slot because the mother's translated marriage certificate wasn't notarised to MOE's standard.

The exam itself: structure, scoring, and what the papers really test

This is the section most online "AEIS exam guide" posts get wrong because they copy from each other. Here's what actually happens on test day, broken down by level.

Primary level (entry into P2–P5)

Two papers, both on the same day:

• English: ~1 hour 50 minutes. Vocabulary MCQ, grammar MCQ, comprehension cloze, open-ended comprehension. The comprehension passages are pitched at roughly one year above the entry level — so a child applying for P4 reads at P5 difficulty.
• Mathematics: ~1 hour 30 minutes. MCQ + short-answer + long-answer word problems. Singapore maths is famously application-heavy. Pure computation is maybe 30% of marks; the rest is multi-step word problems, bar models, and reasoning.

Secondary level (entry into Sec 1–Sec 3)

• English: ~2 hours 10 minutes. Includes a writing component (situational writing + composition) on top of grammar, vocabulary, and comprehension. The writing is where overseas students from rote-memorisation backgrounds get filtered out.
• Mathematics: ~1 hour 30 minutes. Algebra, geometry, statistics, with the same multi-step-problem flavour. For Sec 3 entry, the syllabus reaches into O-Level territory.

What the score reports don't tell you: there's roughly a 30–40% offer rate in a typical year, but it varies dramatically by level. P2 and P3 are easier to enter (more vacancies, fewer applicants). P5 entry is the hardest band — schools are reluctant to take a P5 student who'll sit PSLE just two years later. Sec 3 is similarly tight because of the looming O-Levels.

If your child is borderline P5 / Sec 3 in age, seriously consider applying one level lower. A child who enters P4 instead of P5 gets an extra year to acclimatise before PSLE — and PSLE matters far more than which year of primary school they joined. I cover this trade-off in detail in the PSLE 2026 Timeline and Milestones: A Parent's Calendar.

The AEIS application process, step by step

The AEIS application process has six concrete steps. None of them are hard individually. The failure mode is doing them in the wrong order or leaving them too late.

Step 1 — Confirm eligibility (Apr–May 2026). Your child must hold a foreign passport. Singapore PRs and citizens don't sit AEIS — they go through the regular admission exercise. Age cut-offs are strict: as of 1 January of the year of admission, the child must fall within the age band for the level applied for. Off by even a month and the system rejects you.

Step 2 — Gather documents (May–Jun 2026). Passport bio page (child + both parents), birth certificate, latest two years of school reports, vaccination records, parents' employment pass or in-principle approval if relevant. Anything not in English needs certified translation.

Step 3 — Register online (Jul–Aug 2026). MOE's portal opens for a fixed window. Pay the registration fee (around S$893 currently for AEIS — check the live figure when you register; it's adjusted periodically). Upload documents. Receive your test slot.

Step 4 — Sit the exam (Sep–Oct 2026). Test centres are in Singapore. Yes, you fly in. Plan accommodation early — September is a busy travel month and hotels near test venues fill up.

Step 5 — Wait for results (late Dec 2026). No early results, no inquiries, no appeals. The portal updates and you'll get an email.

Step 6 — Accept and report (Jan 2027). If posted, you have a tight window to accept and report to the school. Failing to report on time forfeits the place.

A practical note: if both parents work overseas, decide early which parent will accompany the child to Singapore for the exam. Some families fly in for just the test week and fly back; others use the trip to scout neighbourhoods, since school posting depends on residential address.

Real costs of Singapore international student admission

Most blogs quote the AEIS registration fee and stop there. The full cost picture for a family pursuing Singapore international student admission looks more like this — these are 2026-realistic ranges, not the cheapest possible numbers:

For families relocating one parent + child, the all-in first-year cost typically lands between S$60,000 and S$110,000. Families where the working parent stays overseas and the child lives with a relative or guardian in Singapore can compress this — but MOE's stance on guardianship arrangements is increasingly strict, and you should verify current rules before banking on this route.

The cost gap between government-school-via-AEIS and a private international school is still significant — international schools start around S$30,000–S$50,000 in tuition alone. That gap is why AEIS remains the route of choice for families committed to long-term integration.

How to actually prepare (without burning out a 9-year-old)

I'll be direct: most preparation programmes I've reviewed are too generic. They drill question types without addressing the underlying gap, which for 80% of overseas children is English reading speed and inferential comprehension.

A reasonable 12-month preparation arc looks like this:

Months 1–3: Diagnostic and foundation. Get a clear picture of where the child actually is. Have them sit a real past-year AEIS paper under timed conditions. Don't tutor towards the test yet — first close vocabulary and grammar gaps. For maths, identify whether the gap is concept (they don't know fractions) or framing (they know fractions but can't parse a Singapore-style word problem).

Months 4–8: Singapore-style immersion. This is where most overseas families undertrain. The child needs to read Singapore-curriculum materials daily — not test prep books, but actual P3 / P4 / P5 textbook and storybook English. Reading speed is the single biggest predictor of comprehension scores. Aim for 30 minutes of unfamiliar English text per day, every day.

Months 9–11: Targeted practice. Now you do timed past papers, weekly. Mark them honestly. Identify the recurring error pattern — for most children it's one of three things: vocabulary precision in cloze, inference in open-ended comprehension, or careless arithmetic in maths long-answer.

Month 12: Tapering. Two weeks before the exam, reduce volume. Sleep matters more than one extra past paper. A tired child loses 10–15% on comprehension simply from concentration drop.

What I'd avoid: signing up for an "AEIS bootcamp" that promises pass-or-refund. Read the fine print — refunds usually require near-perfect attendance and don't account for school placement, only score thresholds. The marketing is louder than the methodology.

For families whose children are coming from non-English-medium schooling, the realistic preparation runway is closer to 18–24 months, not 12. Be honest about your starting point.

Common pitfalls I see every year

After three years of fielding parent questions, the same five mistakes repeat:

1. Assuming a high score guarantees a place. It doesn't. Posting depends on home address and school vacancies. Families who rent in saturated zones (popular East-side and central neighbourhoods) often don't get posted even with strong scores.

2. Underestimating English writing. For Sec-level applicants especially. A child can have native-level spoken English and still write a composition that scores poorly because it lacks the structural conventions Singapore markers expect.

3. Booking the September exam trip late. Test slots and hotels both fill. By August, you're paying double for both.

4. Skipping the medical/vaccination paperwork. Singapore has strict immunisation requirements for school entry. If your child is missing required vaccinations, sorting it out in January while also reporting to school is brutal.

5. Not having a Plan B. What happens if AEIS doesn't yield a place? Will you sit S-AEIS in February? Switch to private/international school? Return home for a year and try again? Decide this before the September exam, not after the December rejection.

For a deeper dive into the overseas-family-specific decisions, I've written AEIS for Overseas Families: The 2026 Complete Guide — it covers the relocation and guardianship side that this guide only touches.

What "good preparation" looks like in practice

Concretely, in the families whose children have placed successfully into government schools, I see a few common patterns:

• They started preparation 12–18 months out, not 3 months out.
• They prioritised reading volume over test drilling for the first two-thirds of the runway.
• The accompanying parent (usually the mother) learned enough about Singapore curriculum framing to coach informally at home, not just outsource to tutors.
• They visited Singapore at least once before the exam trip — to understand neighbourhoods, school catchment, daily life.
• They had a clear, written Plan B for the December scenario where no place is offered.

What I rarely see in the successful cases: families who hired the most expensive tutor, families who relocated one full year early with no plan, families who assumed AEIS was "like IELTS" because someone on a forum said so.

The integration question nobody discusses

Passing AEIS is the easy part of this story. The harder part starts in January 2027 when your child walks into a Primary 4 classroom where every other student has been doing Singapore maths since Primary 1, where the mother tongue policy means they're suddenly in Higher Chinese class, and where the social hierarchy was set in P1.

Most overseas children take 9–18 months to fully settle. The first six months are genuinely hard — academically and socially. Plan for this. Build in a parent-presence buffer if you can. Don't simultaneously launch a new business, a new marriage logistics arrangement, and a child's first term in Singapore school. I've seen that combination break families.

The children who thrive are usually the ones whose families treated AEIS not as a finish line but as a starting line. The exam gets you in the door. The next two to three years determine whether your child is at home in the system or always slightly outside it.

Next steps — what to do this week

If you've read this far and you're seriously considering AEIS for your child, here are concrete actions to take in the next seven days:

• Bookmark moe.gov.sg and check the AEIS page weekly from June onwards — the 2026 calendar is the only definitive source.
• Get a baseline score now. Have your child attempt one past-year AEIS paper for their target level. The result will tell you whether you have a 6-month or an 18-month runway.
• Start the document gathering today. Translations and notarisations take longer than expected, especially for documents from second-tier mainland cities.
• Have the honest family conversation about Plan B. If December 2026 brings no offer, what happens? Write the answer down before the September exam, not after.

The families who treat this seriously and start early have a meaningfully better outcome than those who treat AEIS as a single test to be crammed for. It's not a test. It's the first eighteen months of your family's relationship with Singapore.
