When you sit down with the Secondary 1 option form after PSLE results, you will notice that some schools on your shortlist are boys’ schools or girls’ schools, while most are co-educational. For many families the single sex vs co-ed school question is one of the first real decisions about what kind of environment their child will grow up in for the next four or five years.
There is no universally right answer. Good and caring schools exist in both categories, and children thrive in both. This guide sets out how the two types tend to differ in Singapore, on culture, CCAs and daily life, and how to match that to your child’s personality. For a general checklist covering academics, programmes and location, see Choosing a Secondary School in Singapore.

What Single-Sex Schools Look Like in Singapore
Most single-sex secondary schools in Singapore have long histories. Many were founded by mission or community organisations and are now government-aided schools, while a few are independent or autonomous schools. As a result, several share a few features:
- Strong traditions and identity. Long-established school songs, houses, alumni networks and annual events that students take pride in.
- Affiliated primary schools. Many single-sex secondary schools have affiliated primary schools, which can affect posting for children from those schools.
- A religious or values ethos in some cases. Mission schools usually welcome students of all faiths but may hold chapel services, assemblies or values lessons linked to their founding tradition. Ask the school how this works in practice.
These are tendencies, not rules. Each school is different, and plenty of co-ed schools also have strong traditions and active alumni.
What Co-Ed Schools Offer
The majority of secondary schools in Singapore are co-educational. They range from newer schools with modern facilities to long-established neighbourhood schools with loyal communities. Co-ed schools tend to offer:
- A mix that mirrors daily life. Students learn, work and compete alongside peers of all genders, which some families see as good preparation for junior college, polytechnic, ITE and work.
- More choice near home. Because there are many more co-ed schools, it is often easier to find one with a short commute and the right programmes.
- A wide range of CCAs and programmes. Many have Applied Learning and Learning for Life programmes and a broad CCA list.
Comparing the Two at a Glance
The table below summarises common differences parents raise. Use it as a starting point for questions, not a verdict on any particular school.
| Factor | Single-sex school | Co-ed school |
|---|---|---|
| Social setting | Friendships and classroom dynamics within one gender during school hours | Mixed classes and friendships from Secondary 1 |
| CCAs | Teams and groups are all one gender; some schools have long-running flagship CCAs | Mixed and gender-specific teams; range depends on the school |
| School culture | Often strong heritage, traditions and alumni ties | Varies widely, from heritage schools to newer ones |
| Number of options | Fewer schools, so fewer near any one home | Many more schools across every region |
| Affiliation | Many have affiliated primary schools | Some have affiliations, many do not |
Matching the School to Your Child’s Personality
The most useful question is not “which type is better?” but “where will my child do well?”. Think about these traits honestly, ideally together with your child.
Confidence in class. Some children speak up more readily in a single-sex setting; others are equally comfortable anywhere. If your child tends to hold back, ask how teachers at each school encourage participation.
Friendships and social style. A child who enjoys close friendships with peers of all genders may find a mixed school more natural. A child who prefers a smaller, familiar social circle may like the tight-knit feel some single-sex schools have, though this varies by school.
Interests and CCAs. If your child is set on a particular sport, uniformed group or performing arts CCA, check which schools offer it at a level that suits them. CCA offerings vary far more between individual schools than between school types.
Values and family background. Some families want continuity with a school a parent or sibling attended. Others prefer a school without a religious ethos, or specifically want one. Both are fair considerations.
Readiness for a long commute. Since single-sex schools are fewer, choosing one may mean a longer daily journey. A tiring commute can affect sleep, homework time and CCA participation. Our guide to comparing secondary school commutes can help you weigh this.
Questions to Ask at Open Houses
Open houses and school websites are the best way to see past general impressions. Questions worth asking at any school:
- How do students mix across classes and levels, and how does the school build a sense of belonging in Secondary 1?
- Which CCAs are most active, and how are students allocated if a CCA is oversubscribed?
- How does the school handle peer relationships, online behaviour and wellbeing?
- What links does the school have with other schools, for example joint events or combined CCAs between boys’ and girls’ schools?
- For schools with a religious founding tradition: what religious activities are part of the timetable, and are they compulsory?
Talking to current students or recent graduates, where possible, often gives the most honest picture.
Common Myths to Set Aside
- “Single-sex schools always get better results.” Results depend on many factors, including the school’s intake. Look at the programmes and teaching approach, not just reputation.
- “Co-ed schools are more distracting.” Children can be distracted anywhere. School culture and expectations matter more than whether classes are mixed.
- “My child must go where their sibling went.” Siblings can have very different needs. One child’s ideal school may not suit the other.
Putting It on the Option Form
Once you have a shortlist, rank schools by genuine preference, mixing in some safer choices based on your child’s PSLE Score and the schools’ recent cut-off points. Whether a school is single-sex or co-ed should be one of several factors, alongside fit, programmes and travel, not the only one. After posting, Supporting the Move to Secondary School has tips to help your child settle in whichever type of school they join.
Key Takeaways
- Both single-sex and co-ed schools in Singapore can provide excellent, caring environments.
- Single-sex schools are fewer and often have strong heritage and affiliations; co-ed schools are more numerous and closer to most homes.
- Choose based on your child’s confidence, social style, interests and stamina for travel.
- Use open houses to test general impressions against each school’s reality.
- Treat school type as one factor among several when ranking your S1 choices.
