Use the Singapore Junior Biology Olympiad (SJBO) registration page maintained by the Singapore Institute of Biology. Start with your school’s biology or science coordinator, then check the organiser’s instructions for the intended edition.
There is an important alternative route: the registration page names an appointed exam centre for students unable to register through school. Follow that link from the organiser’s page and confirm current arrangements. Do not copy another olympiad’s rule that individual or centre-based entry is impossible.
The published timeline is for 2026: registration ran from 13 February to 13 March, and the theory round was on 6 May. These dates have passed as of 17 October 2026; the presence of a 2026 form does not establish that a future entry window is open.

Practical checks before you act
Confirm the route before sending personal details
If the school is registering participants, ask who coordinates the list and what you need to provide. If that route is unavailable, return to the organiser’s appointed-centre link rather than assuming any tuition provider or competition centre can register you.
Before submitting information, check the centre’s current notice against the organiser’s page. Ask which edition it covers, whether registration is actually open and how completion will be confirmed. An old centre listing is a starting point for verification, not a guarantee of a future place.
Use the correct forms and read what they require
The registration page links both a 2026 registration form and an NDA form. Open the documents for the relevant edition and read them before submission. This guide does not replace their instructions or interpret the agreement on your behalf.
Keep a simple record of the version used, what was submitted and any acknowledgement received. If something is missing, ask the school or appointed centre how to correct it. Avoid circulating completed forms containing personal information in public study groups.
Separate an old format from current instructions
Did you know? The current registration page says SJBO will no longer have a practical round. That makes an old preparation schedule containing a practical stage a poor substitute for checking the organiser’s current notice.
Read the intended edition’s briefing materials for eligibility, format and arrangements that matter to you. If the next edition is not yet published, label your notes as provisional. Do not infer a new date, venue or assessment stage from a previous year’s calendar.
Prepare around biological reasoning, not an assumed route to an award
For a useful self-check, take a question from your existing biology study materials and explain the mechanism behind your answer. Then ask which observation or piece of data could challenge that explanation. This is a suggested learning exercise, not an official SJBO task.
A teacher can help you distinguish a knowledge gap from a problem interpreting an unfamiliar diagram or experiment. Keep ordinary school learning and optional enrichment in a manageable balance. Participation is an opportunity to learn; it does not itself decide future subject eligibility or university admission.
What to do next
Check the organiser’s registration and timeline pages first, then confirm the school or appointed-centre route for the correct edition. Use eduKate’s science-olympiad learning guide for the separate question of preparation and tutor fit, while keeping entry decisions with the organiser.
