Introduction

This Higher tier diagnostic document is intended to support students in accessing the Higher tier of the new GCSE
(9–1) Mathematics specification.

This document lists the units in the Highertier scheme of work, suggests questions to establish whether a student has the required prior knowledge, and provides a mapping of references to the Foundation scheme of work (and occasionally the Access to Foundation tier scheme of work) should the student need to refresh their understanding or develop a particular skill. Teachers can then turn to the relevant unit(s) in the Foundation scheme of work for additional support, including objectives, possible success criteria, opportunities for reasoning and problem-solving, and common misconceptions.

For later Highertier units, prior knowledge has sometimes not been covered in the Foundation scheme of work. In these instances, a reference to an earlier Higher tier unit is provided, along withdiagnostic questions to check that this knowledge has been acquired.

Our free support for the GCSE Mathematics specification (1MA1) can be found on the Edexcel mathematics website ( and on the Emporium (
