Physics Olympiad Difficulty Ladder
The Pathway at a Glance
Stage 1: Singapore Junior Physics Olympiad (SJPO)
Stage 2: Singapore Physics Olympiad (SPhO)
Q: What is the physics olympiad pathway in Singapore? A: Singapore has a four-stage competition ladder: the Singapore Junior Physics Olympiad (SJPO) for Secondary 2--3 students, the Singapore Physics Olympiad (SPhO) for JC/IP Year 5--6 students, the Asian Physics Olympiad (APhO) for top SPhO performers, and the International Physics Olympiad (IPhO) as the pinnacle. Each stage feeds into the next, with selection processes managed by IPS and NUS Physics.
TL;DR Singapore's physics olympiad ladder runs SJPO → SPhO → APhO → IPhO. SJPO is the junior entry point (Sec 2--3). SPhO is the senior national contest (JC/upper IP). Top SPhO performers are considered for the APhO team, and the strongest are selected for IPhO - the world championship. Each stage has its own detailed guide linked below.

The physics olympiad pathway is SJPO, SPhO, APhO, then IPhO.

Check current level, school nomination, theory depth, practical readiness, training load, selection stage, lab skills, and whether the next rung fits school workload.

Progress is usually gradual: build mechanics, circuits, waves, data analysis, and proof-style explanation before chasing international selection.
Concrete example
A Sec 3 SJPO student should strengthen force diagrams and graph interpretation before worrying about IPhO-level electromagnetism.
Best next step
Identify the next realistic competition and plan one theory block plus one practical-skill block each week.
Practical rounds matter: Both SPhO and IPhO include experimental components worth significant marks. Students who train only on theory are often surprised by the practical round - start building lab skills (measurement, uncertainty analysis, data graphing) alongside theoretical preparation. See our SPhO Practical Round Guide for details.
The SJPO is the entry point for younger students - typically Secondary 2 and 3. It is organised by the Institute of Physics Singapore (IPS) and hosted at NUS. Schools nominate candidates; individual registration is not available. The competition has historically consisted of a General Round (MCQ) and a Special Round (written, by invitation for top scorers). Doing well at SJPO builds confidence and early exposure, though SJPO results do not directly qualify students for SPhO.
The SPhO is the senior national physics competition, typically for JC1/JC2 or IP Year 5--6 students. It is jointly organised by IPS and the NUS Department of Physics. Schools nominate students, and the contest involves theory-based papers. Top SPhO performers are identified for further training and selection towards the international competitions. This is the critical gateway: strong SPhO results are what lead to APhO and IPhO consideration.
The APhO is a regional international competition drawing teams from across the Asia-Pacific. Singapore selects its APhO team primarily from top SPhO awardees, who then undergo additional national training. The APhO format includes both a theory paper and an experimental exam, making it a significant step up from SPhO. Performance at APhO also informs the final IPhO team selection.
The IPhO is the pinnacle of the physics olympiad pathway. Each country may send up to five contestants. The competition consists of two five-hour exams - one theoretical and one experimental - held on separate days. Singapore's IPhO team is drawn from the national training squad, with final selection informed by SPhO and APhO performance plus dedicated national trials. Representing Singapore at IPhO is a distinction that carries weight in university admissions worldwide.
Olympiad physics builds on - and goes well beyond - the school syllabus. Students aiming for this pathway benefit from having a strong grasp of their core school physics first. A solid foundation in mechanics, waves, electricity, and modern physics makes olympiad-level problem solving far more accessible.
IP Physics Tuition - for IP students building the fundamentals from Secondary 3 onwards
A-Level Physics Tuition - for JC students strengthening H2 Physics alongside competition prep
Eclat Institute does not offer olympiad-specific tuition. Our focus is on helping students build the strong conceptual and problem-solving foundations that make olympiad self-study and school-based training programmes more effective.
Frequently Asked Questions
Do I need to do well in SJPO to qualify for SPhO?
No. SJPO and SPhO are separate competitions with independent registration. SJPO is aimed at younger students (Sec 2--3), while SPhO targets JC/upper IP students. You do not need SJPO results to enter SPhO - school nomination is the entry mechanism for both. That said, SJPO is excellent early exposure.
How is the Singapore IPhO team selected?
The selection process is managed nationally. In general, top SPhO awardees enter a training programme, participate in selection tests, and may represent Singapore at APhO. The final IPhO team of up to five students is chosen through national trials. Check the official NUS Physics olympiad pages for the current selection process.
Can I sign up for these competitions individually?
For SJPO and SPhO, registration is through schools - individual sign-ups are not available. Speak to your physics teacher or teacher-in-charge of competitions. APhO and IPhO selection is by invitation through the national training programme.
What topics should I study beyond the school syllabus?
Olympiad physics typically covers mechanics, thermodynamics, electromagnetism, optics, and modern physics at a deeper level than H2 Physics. Experimental skills are also tested at APhO and IPhO. Past papers and the official syllabi (available on the IPhO and APhO websites) are the best guide to scope.
Is olympiad participation useful for university applications?
Yes. Strong olympiad results - especially at the national (SPhO) and international (APhO, IPhO) level - are recognised by top universities in Singapore and abroad. Many scholarship applications also ask about competition achievements.
