The mid-year intake for expat children who missed the main AEIS cycle
What the S-AEIS is
The S-AEIS is the supplementary AEIS sitting. It exists for children who were not placed in the main cycle, or who arrived in Singapore after the main registration window had closed.
A child who is successful in the S-AEIS starts local school in April or May, not in January. That is the practical difference most families care about: the same test structure, a later start, and a shorter runway before the school year catches up with them.
The S-AEIS is not an easier route. It uses the same format and syllabus as the main cycle, at a different time of year. Treat the preparation the same way you would treat the main cycle.
The 2027 dates, as they stand
As of 20 October 2026, MOE has not published the S-AEIS 2027 dates. The pattern from previous years is:
- Applications open in early January 2027.
- Tests are held at the end of February or in early March 2027.
- Successful children start school in April or May 2027.
Those are planning dates, not confirmed dates. MOE publishes the confirmed window on its official S-AEIS page, and that page is the only version that counts. Check it before you book a Cambridge English test, before you book travel, and before you tell your child a date.
If you are aiming for the main AEIS cycle instead, that registration usually opens in July, with tests in September. The same rule applies: the 2027 main-cycle dates are not published yet.
Who can apply
The S-AEIS is open to international students who do not have a place in a local school and who meet the age and level criteria for the year of admission.
Two things catch families out:
- Eligibility is checked against date of birth and admission year, not against the school year your child is in now. A child who is in P5 at an international school may be routed to a different level than the parent expects.
- The main AEIS and the S-AEIS can route the same child to different levels. This affects older primary applicants most. Do not assume the level you were told for one cycle applies to the other.
Use MOE's official eligibility checker for the S-AEIS before you plan anything. It takes a few minutes and it prevents the most expensive mistake in this process, which is preparing for the wrong paper.
The Cambridge English requirement comes first
Primary applicants cannot register for the S-AEIS mathematics paper until they hold a qualifying Cambridge English Qualification (CEQ) result.
The CEQ is booked privately through a registered Cambridge centre, not through MOE. It has to be completed early enough for the result to be in hand when the S-AEIS application window opens. In practice, that means sitting it in the second half of the year before, not in January.
Two Cambridge tests are used:
- A2 Key for Schools for the Primary 2, Primary 3, and Primary 4 routes, including eligible older children routed through the S-AEIS Primary 4 route.
- B1 Preliminary for Schools for the main AEIS Primary 5 route, including eligible older children applying for Primary 5 through AEIS.
The exact test and the minimum score depend on your child's date of birth, the admission year, and the route. Confirm both with MOE's eligibility page before you book a test. The full explanation is in the CEQ requirement guide.
Documents to prepare before January
The application itself is short. The preparation around it is not. Have these ready before the window opens:
- Your child's birth certificate, with an official English translation if it is not already in English.
- Your child's passport bio-data page.
- The Cambridge English Statement of Results.
- Any previous AEIS or S-AEIS result, if your child has sat the test before.
- A payment method for the application fee.
Documents that are scanned badly, cropped, or in the wrong format are a common reason an application stalls. Prepare clean digital copies in advance, not on the last day.
How the application works
The application is submitted through MOE's Candidates Portal. You create an account, enter your child's details, upload the documents, choose the level, and pay the fee.
Three rules make the difference between a smooth application and a rejected one:
- The level you select is the level your child is tested at. It is not a preference to be adjusted later.
- The documents must match the details you enter. A misspelled name or a mismatched date of birth creates a manual review.
- Submit before the window closes, not on the day it closes. Traffic and payment failures at the deadline are avoidable.
Applications go through the portal, not by email. If someone offers to submit it for you, you are still the one responsible for what is entered.
What happens after the test
MOE releases the placement outcome after the test window. If your child is placed, you report to the school within the stated window and complete the remaining administrative steps, including any Student's Pass follow-up that applies to your family.
A placement is not the end of the process. The first six months in a local school are where most families need the most support: the pace of English, the way mathematics is presented, and the size of the class. Plan for that period before the result arrives, not after.
What to do while you wait
The waiting period is not dead time. Children who keep a daily reading habit and continue mathematics practice arrive at the test calmer than children who stop and restart.
- Keep reading daily, in English, at a level your child can enjoy.
- Keep mathematics practice short and regular rather than long and occasional.
- Run one timed paper closer to the test, then work through the errors rather than the score.
If you want the full preparation sequence, read the AEIS preparation guide. If the mathematics paper is the part you need help with, AEIS maths tutoring starts with a diagnostic lesson rather than a package.
