Prof Sparks called for the majority of pupils to study maths up to the age of 18, and said that some teenagers should take tailored courses “between a GCSE and A-level”. “The reason some people are being put off maths is related to that issue of teaching to the test,” he said. “Schools are given a big incentive to make sure pupils pass tests, which doesn’t necessarily mean that they get the well-rounded understanding that a good education requires.”
