For many Singapore families with a child who thrives in Mathematics or Science, NUS High School of Mathematics and Science sits at the very top of the secondary school wish list. It is not hard to see why. The school offers a distinctive six-year programme, a university-affiliated diploma, and a learning environment purpose-built for students who do not just study STEM subjects but genuinely love them.

Yet the admission process can feel opaque, especially for first-time applicants. Unlike most secondary schools, NUS High does not participate in the standard Secondary 1 (S1) Posting Exercise. Every single place is filled through a specialised pathway, which means preparation, timing, and understanding the selection criteria are all critical. Whether your child is in Primary 6 and preparing for the DSA-Sec exercise or in Secondary 2 and considering the Year 3 transfer, this guide walks you through everything you need to know — from eligibility and application steps to school fees, the curriculum, and practical preparation advice.

What Is NUS High School of Math & Science?

NUS High School of Mathematics and Science (commonly known as NUS High or NUSH) is a Specialised Independent School located at 20 Clementi Avenue 1. It offers a six-year Integrated Programme (IP) leading to the NUS High School Diploma, with a school motto of “Experiment. Explore. Excel.”Unlike other IP schools, it does not offer the GCE A-Level or the International Baccalaureate. Instead, it awards its own NUS High School Diploma, which is recognised by all universities in Singapore as well as universities worldwide.

Established in 2005, the school is an independent, specialised co-educational institution offering a six-year diploma programme accredited by the Ministry of Education and the National University of Singapore.It is the only IP school in Singapore that specialises in mathematics and science and leads to the NUS High School Diploma.The school admits approximately 170 to 180 students annually through the DSA-Sec process, selecting from around 2,000 applicants — typically the top 10% of Singapore’s primary school cohort based on aptitude in mathematics or science.

In the most recent accreditation in 2023, the Ministry of Education Singapore and the National University of Singapore concluded that NUS High’s Math, Science, Humanities, Art and Music Majors are beyond H2 A-level standard. That is a remarkable benchmark and a big part of what makes the school so compelling for academically ambitious students.

Admission Pathways: Year 1 and Year 3

NUS High School admits students at two entry points: Year 1 (equivalent to Secondary 1) and Year 3 (equivalent to Secondary 3). All admitted students join in January of each calendar year.The school does not participate in the S1 posting process; instead, interested students apply through the Direct School Admission for secondary schools (DSA-Sec).

As a specialised independent school, NUS High School can admit 100% of its Secondary 1 intake through DSA-Sec. This means there is no back-door entry via PSLE results alone. If your child is aiming for NUS High, the DSA-Sec exercise is the only route in at Year 1 — making early preparation all the more important.

Year 1 Admission (P6 Students): The DSA-Sec Process

Primary 6 students apply for Year 1 admission through the MOE Centralised DSA-Sec Online Portal. Here are the key points every parent should know before applying:

• Talent Areas:NUS High accepts applications under both the “Mathematics” and “Science” talent areas. Students should apply under one talent area only, as the selection test covers both subjects. There is no need to submit two choices for the same school.
• Portal Registration:Interested applicants must register at the MOE Centralised DSA-Sec Online Portal during the application period.Application through the portal is free-of-charge and requires one parent’s SingPass to log in for authentication purposes. Parents who do not have SingPass access can approach their child’s primary school for assistance.
• Don’t Double-Apply:Applicants need to register only once in either “Math” or “Science”. Students should not select NUS High School twice, as they only have three DSA choices.
• After an Offer is Made:Successful DSA applicants are not eligible for school transfer after the release of the PSLE results and cannot participate in the S1 Posting Exercise. This is a firm commitment, so families should be certain before accepting.

For Year 1 DSA-Sec applicants, the supporting documents required include a portfolio with scanned copies of the P5 and P6 school report books and any Mathematics and Science related accomplishments, such as certificates and awards, submitted within the first three days of PSLE Results Release.

Year 3 Admission (Sec 2 Students)

Students who did not enter NUS High at Year 1 have a second opportunity at the Year 3 entry point. For admission to Year 3, local mainstream secondary school applicants must be enrolled in the Secondary Two “Express” course of study at the time of application.In addition, applicants must be born between 2010 and 2012 and should not be older than 17 years of age as of 1 January 2027.

It is worth noting that this pathway is not open to everyone. The Year 3 Admission is not open to Singapore mainstream school Secondary Two students who are currently studying in an IP school or IP track, or who were posted to a secondary school under the DSA-Sec Exercise or AEIS.For Year 3 applicants, the required supporting documents include P6 to Secondary 2 report books, as well as Mathematics and Science related accomplishments such as certificates and awards (optional).

The Selection Process: Tests, Camp, and Interview

The selection process for NUS High is multi-staged, and understanding each stage helps families prepare effectively. The selection process consists of three stages: a Selection Test with one Mathematics paper and one Science paper (for all applicants), a one-day Selection Camp with various Mathematics and Science activities (for around the top 500 shortlisted applicants), and a Selection Interview for applicants that require further assessment.

Here is what each stage involves:

1. Stage 1 — Selection Test:Shortlisted candidates are invited to sit for the Selection Test, which assesses their proficiency in mathematics, science, and English. The test is designed not just to check syllabus mastery but to assess how well students can reason through unfamiliar problems. Preparation beyond the standard school curriculum gives students a meaningful edge.
2. Stage 2 — Selection Camp: Students who perform well in the test are invited to a one-day selection camp held at the school. This camp aims to identify students who can work well in a Math and Science school environment, show enthusiasm for the subjects, and demonstrate proactiveness. Activities are collaborative, and students are assessed on how they engage with problems and with others in a group setting.
3. Stage 3 — Interview:Students who perform well in the selection tests are invited for an interview. The interview panel typically includes school faculty and administrators who assess the candidate’s motivation, curiosity, and suitability for the school’s rigorous academic environment.

Shortlisting for the camp and interview is based on performance in the Selection Tests, primary school test and exam results (mastery of the primary school syllabus in Mathematics and Science), participation and achievements in Mathematics and Science related competitions and programmes, as well as related CCA accomplishments such as certificates and awards.

What NUS High School Looks For in Applicants

NUS High School considers various qualities and attributes and does not focus on students’ past achievements alone. This is an important nuance for parents to understand. A string of competition trophies matters, but it is not the whole story. The school is genuinely looking for intellectual curiosity — students who find Mathematics and Science interesting because they cannot help themselves, not simply because it scores well on a report card.

Students are assessed across three areas: academic performance in school, particularly in Mathematics and Science; a portfolio showcasing their passion and aptitude in Mathematics and/or Science; and performance in the DSA selection instruments such as tests, camp, and interview.

NUS High’s selection process is notably different from mainstream school DSA. Shortlisted students typically undertake a structured assessment that tests reasoning quality in mathematical and scientific problem-solving — not knowledge recall. The interview emphasises intellectual curiosity, the ability to approach genuinely unfamiliar problems, and authentic evidence of the student’s thinking process over time.

However, the school highly recommends that applicants be reading G3 Mathematics and G3 Science in their current school, as this better aligns with the academic expectations. Students on the standard stream will find the transition more challenging.

Inside the NUS High School Curriculum

One of the things that sets NUS High apart is how genuinely different its academic structure is from every other school in Singapore. The diploma’s curriculum is built on a 2-2-2 structure, with the first two years being the Foundation Stage, the second two the Advancement Stage, and the final two the Specialisation Stage.Studies are based on a modular system similar to NUS, where core modules are compulsory, elective modules help deepen the student’s knowledge, and enrichment modules are purely for the student’s interests.

The school uses a 5-point grade point average (GPA) system, similar to the system used worldwide.Diploma classifications range from Pass (2.5–2.9) to Merit (3.0–3.9), Distinction (4.0–4.4), and High Distinction (4.5–5.0). Students must maintain a minimum Cumulative Average Point (CAP) of 2.5 to progress each year.

The curriculum goes well beyond Mathematics and Science. Subjects span Mathematics and Sciences (Mathematics, Biology, Chemistry, Computer Science, Physics), Humanities, Art and Music (including English Literature, Geography, History, Art, and Music), Humanitarian Education and Student Leadership, and Languages including English, Mother Tongue, French, Japanese, Chinese Special Programme, and Malay Special Programme.

Beyond the classroom, NUS High runs several signature enrichment programmes:

• Da Vinci Programme — focused on Research, Innovation and Enterprise
• Galileo Programme — a satellite engineering track
• EINSTEIN+ Programme — talent development for the most advanced students
• TESLA Initiative — centred on Technopreneurship and STEM
• Voyager Programme — internationalisation experiences
• Atlas Initiative — leadership and service

Over 70% of NUS High graduates have pursued Science, Technology, Engineering and Medicine-related courses at university. For students passionate about STEM, this is a community that genuinely shares their interests and ambitions.

On the co-curricular front, CCA is considered a core but non-examinable module at NUS High School, and it is compulsory for every student to participate in one school-based CCA from any of the four categories: Clubs and Societies, Performing Arts, Sports, and Uniformed Groups.The school offers 24 CCAs spanning Sports, Performing Arts, Uniformed Groups and Clubs and Societies.

School Fees

As a Specialised Independent School, NUS High charges fees that vary based on the student’s citizenship status. The 2026 monthly school fees are: S$300 for Singapore Citizens, S$1,090 for Singapore Permanent Residents, S$1,885 for International Students (ASEAN), and S$2,995 for International Students (non-ASEAN). There is also a miscellaneous fee of S$30 per month per student.

For Singapore Citizen families, the monthly fee of S$300 is relatively affordable compared to international school alternatives, especially given the depth and breadth of the programme on offer. Financial assistance is available for needy Singapore Citizens through the MOE Financial Assistance Scheme, and the school also provides subsidies for the boarding programme for qualifying students.

Preparation Tips for Parents and Students

Given how competitive NUS High admissions are, early and purposeful preparation is important. Here are practical steps families can take:

1. Build genuine interest, not just credentials. NUS High selects for intellectual curiosity above all else. Encourage your child to read science books, explore mathematics beyond the school syllabus, and ask questions about how the world works. A student who genuinely enjoys the subject will interview very differently from one who has simply been coached.
2. Take G3 Mathematics and G3 Science.The school highly recommends that applicants be reading G3 Mathematics and G3 Science in their current school, as this better aligns with the academic expectations of NUS High.
3. Build a meaningful portfolio.A portfolio showcasing multiple top Mathematics competition awards will help students demonstrate their mathematical proficiency and significantly boost their application. This includes Olympiad participation, science fair entries, or any sustained self-directed project that shows genuine engagement.
4. Practise problem-solving, not just memorisation.The selection process tests reasoning quality in mathematical and scientific problem-solving, not knowledge recall. Students benefit from practising non-routine problems and learning to articulate their thinking process clearly.
5. Prepare for the group dynamics of the selection camp. Collaborative activities at the camp assess how students contribute to a team. Being thoughtful, listening to others, and building on ideas constructively matter just as much as demonstrating individual ability.
6. Apply under one talent area only.NUS High is found under both “Math” and “Science” talent areas, but applicants need to register only once in either subject. Registering twice wastes one of your child’s three DSA choices.

Frequently Asked Questions

Does my child need a very high PSLE score to get into NUS High?

The PSLE scores of students admitted from primary school through the examination phase are mostly in the 264–285 range, while those admitted through DSA-Sec have varying PSLE scores. Because NUS High admits entirely through DSA-Sec, the selection is based on aptitude and the selection process rather than PSLE scores directly — though a strong academic foundation is expected.

Do international students need to sit for the AEIS test?

International students applying for admission to NUS High School do not need to sit for the Admissions Exercise for International Students (AEIS) Secondary test due to the school’s specialised curriculum. However, applicants who are also applying to other mainstream schools in Singapore would need to take and pass the AEIS test before they can be considered for admission to those schools.

When are offers sent out for Year 1 DSA-Sec?

For Year 1 DSA-Sec, successful applicants will be notified and given a Letter of Offer (Confirmed Offer or Wait List) by 28 August via the main contact email address registered with MOE. Parents should ensure the contact email registered with MOE is one they check regularly.

Can a student transfer to NUS High after Year 1?

NUS High School admits students at Year 1 and Year 3 only. There is no transfer option between these two entry points. Students who wish to join in Year 3 must go through the separate Year 3 admission exercise.

Does the NUS High Diploma lead to university admission in Singapore?

The NUS High School Diploma is recognised by the National University of Singapore (NUS), Nanyang Technological University (NTU), Singapore Management University (SMU), and top overseas universities in the Ivy League, Oxbridge, and others. It is a well-respected qualification that opens doors both locally and internationally.

Final Thoughts

NUS High School of Mathematics and Science is a genuinely special institution — one that rewards intellectual curiosity, independent thinking, and a deep love of STEM. The admissions process is rigorous precisely because the school environment demands it. For the right student, it is not just the most prestigious choice; it is the best fit.

The most important thing parents can do is help their child build an authentic relationship with Mathematics and Science, rather than simply accumulating credentials for the application. NUS High’s selectors are experienced at telling the difference. A student who is genuinely curious will find the selection process far less daunting than one who has only been prepared for it from the outside. Start early, stay consistent, and let your child’s natural strengths shine through the process.
