What knowledge of mathematics is required by students?

Students are expected to have basic numeracy skills, including understanding of percentages, ratio and proportion. They should also understand and be able to calculate an average (mean), and be able to represent the chances of something happening in precise numerical terms (i.e. as a fraction, decimal or percentage). No mathematical knowledge beyond this is required.

Simple algebraic skills can be a very powerful tool for problem solving, particularly for more complex problems, but will they never be assessed directly. The focus is on being able to make valid problem-solving insights and deductions, whatever methods are used.
