Q: What does How DSA Math Talent Tests Really Work: Inside the Rubrics, Question Types and Prep Timeline cover?
A: A parent-friendly but technically precise guide to the written & interview-based math assessments IP schools use during Direct-School-Admission (DSA).

TL;DR
DSA-Sec Math selections are talent screens, not mini-PSLEs. Schools set non-routine written tasks and short interviews to see pattern-spotting, proof sketches and communication-skills that align with the IP pathway. Explaining your reasoning matters more than speed on routine sums.
Application window (2025 intake): MOE’s DSA-Sec portal runs 7 May – 3 Jun 2025; schools publish their selection formats by late April MOE DSA-Sec.

Status: MOE DSA-Sec page last checked 2025-11-30 - portal window listed as 7 May – 3 Jun 2025. Schools release format/timeline on their own pages; rely on each school’s 2025 notice when posted.

1 What MOE and schools publish

DSA-Sec is talent-based: Schools use DSA to admit students with strengths in areas such as Mathematics; it is not a re-run of PSLE Maths MOE DSA-Sec.
Selections vary by school: Shortlisted applicants may be asked to sit written tasks and attend interviews, auditions or trials MOE DSA-Sec. Check your target school’s DSA page (e.g. RI Year 1 admissions) for its current format and schedule.
Registration window (2025): MOE portal is open 7 May – 3 Jun 2025; schools usually post their detailed timelines by late April MOE DSA-Sec.
Typical components: A timed non-routine written paper, a short interview/viva, and a review of your portfolio (Olympiad results, projects, or math logs). Exact lengths and weights differ by school and year-use the published school notice as your ground truth.

2 Question Types Demystified

2.1 Pattern Generalisation

Introduces 3-4 term patterns, asks for the $n$ -th term or closed form.
Sample:

"The sum \(S

Month	Student action	Parent support	Why now
Oct 2024	Diagnostic paper $→$ map weak strands.	Book enrichment only if needed.	8 months prep = gentle ramp.
Dec	Finish pattern & proof block.	Family puzzle nights (Koh's Math Olympiad Trainer).	Keeps practice light but regular.
Mar 2025	Sit a full timed non-routine mock.	Timekeeper, mark with rubric.	Builds stamina + realism.
Apr	Practise think-aloud interview clips.	Feedback on clarity, pace.	Muscle memory for viva.
May 7 - Jun 3	Submit via MOE DSA-Sec portal.	Collate portfolio PDFs.	Portal window per MOE.
Jul - Aug	School-based tests & interviews (per school schedule).	Logistics, rest, growth talk.	Peak performance window.

Pitfall	Why it backfires	Quick fix
Drilling PSLE TYS	Tests routine skills; DSA wants abstraction.	Use SMOPS, NMOS, RI Olympiad Jr papers.
Skipping write-ups	Marks for reasoning; sketches only score 2/4.	Force one-sentence "Because…" after each step.
Last-minute speed runs	Stamina beats speed; quality trumps quantity.	30-min deep dive per question variant.
Answer-chasing in interview	Panel values process over final number.	Practise think-aloud with phone recorder.
