NCEA Numeracy · Put your knowledge to work in context.
This page is an independent study guide for the NCEA Numeracy co-requisite, maintained by a private study platform and not affiliated with or endorsed by the New Zealand Qualifications Authority (NZQA). The NCEA Numeracy co-requisite is the numeracy requirement learners in Aotearoa New Zealand need to meet alongside their NCEA programme; it is aimed at secondary students working towards NCEA and at other candidates who need to show the numeracy standard. The exam covers four areas: number and algebra, measurement and geometry, statistics and probability, and using numeracy in real-life contexts. Each area carries equal weight, so no single topic can be skipped, and questions are framed around practical situations rather than abstract drill. The NCEA Numeracy case studies are 5 cases and about 3,022 words.
