Q: What competitions can my primary school child enter? A: Singapore offers several maths and science competitions for primary school students. Some are open from P1 while others start at P3 or P5. This guide maps every major competition to your child's level and links to a detailed profile for each one.
TL;DR Seven competitions cover primary school maths and science in Singapore. SMKC and SMC accept children from P1. SASMO, SPSO and RMO open up from P3 - P4. NMOS and APMOPS are reserved for upper primary (P5 - P6). Registration windows, fees and formats change each year - always check the organiser's official page before registering.

Use the table below to see which competitions your child is eligible for. A tick means that level is accepted; confirm exact eligibility on the organiser's website each year.
Note: Registration details - dates, fees and venues - change every cycle. Always confirm on the organiser's official page before registering.
Competition overviews
SMKC - Singapore Math Kangaroo Contest
SMKC is part of the worldwide Math Kangaroo family and is open to all primary levels (P1 - P6). It uses a multiple-choice format and emphasises logical thinking rather than curriculum-heavy content. SMKC is a good first competition because it is accessible and does not require advanced olympiad preparation.
SMC accepts students from P1 - P6 and focuses on problem-solving skills. It is designed to encourage mathematical thinking beyond the school syllabus without requiring formal olympiad training. The format may vary between cycles.
SASMO is open from P2 - P6 (and extends into secondary school). It uses a multiple-choice format and is calculator-free. SASMO is one of the largest competitions in Singapore with more than 400,000 participants across dozens of countries. It works well as an introduction to olympiad-style questions.
SPSO is the main primary-level science competition in Singapore, open to P3 - P6. It tests conceptual understanding in science through a mix of MCQ and open-ended questions. Strong performance can signal readiness for secondary science olympiads such as SJPO and SJChO.
RMO is organised by Raffles Institution and is open from P4 (Junior category) to P6. It uses a written format and the questions tend to be more challenging than typical MCQ-based competitions. RMO is a useful stepping stone toward more demanding secondary olympiads.
NMOS - National Mathematical Olympiad of Singapore
NMOS is organised by NUS High School and is open to P5 students only. It is one of the most established primary maths competitions in Singapore. Strong NMOS performance is often cited as a signal of readiness for SMO at the secondary level.
APMOPS - Asia Pacific Mathematical Olympiad for Primary Schools
APMOPS is organised by Hwa Chong Institution and targets P5 - P6 students. It includes an invitational round and draws participants from across the Asia-Pacific region. APMOPS questions are among the most challenging at primary level and the competition serves as a direct feeder into SMO and the broader maths olympiad pathway.
If your child is in P1 - P2, start with SMKC or SMC - both are designed to be approachable and fun. From P3 onwards, SASMO is a popular first olympiad because it uses a familiar MCQ format. There is no single "right" answer; choose based on your child's interest and comfort level.
How do I register my child for these competitions?
Registration methods vary. Some competitions (NMOS, RMO, SPSO) are typically registered through your child's school. Others (SASMO, SMKC) also accept private candidates through the organiser's website. Always check the organiser's official page for the current registration process, as it may change from year to year.
Is my child ready for a maths or science competition?
Most primary competitions are designed to be accessible to students who enjoy the subject, not only to top scorers. Competitions like SMKC and SASMO are intentionally broad and are a good way to test the waters. If your child enjoys puzzles, logic games or going beyond the school worksheet, they are likely ready to try.
Does my child need special coaching or tuition before entering?
No. Most primary competitions can be attempted with regular school-level knowledge and some independent practice using past papers (where available from the organiser). Familiarity with the question format matters more than hours of drilling at this level.
How many competitions should my child enter per year?
One or two is a reasonable starting point. Entering too many competitions can turn what should be an enjoyable challenge into a source of stress. Let your child's interest guide the number - some children thrive on variety, while others prefer to focus on one competition and prepare well for it.
Do competition results help with DSA or secondary school admissions?
Some secondary schools consider competition achievements as part of their DSA (Direct School Admission) process, particularly in the Maths and Science talent areas. However, DSA criteria vary by school and year. Competition results are just one factor - schools also look at school grades, CCA involvement, interviews and other evidence of talent and interest.
Are there science competitions for lower primary (P1 - P2)?
At the primary level, the main science competition (SPSO) starts from P3. For P1 - P2 students interested in science, informal activities such as science fairs, maker programmes and curiosity-driven projects can build the foundation before formal competitions become available.
Where can I find past papers to practise with?
Check the organiser's official website first - some competitions release sample papers or past papers directly. For others, your child's school may have practice materials. Be cautious with unofficial third-party compilations, as question formats and difficulty may change between cycles.
