Diagnostics: assessing and addressing children’s difficulties with mathematics

  • by


This programme looks at materials and activities to help teachers assess and address children’s difficulties with mathematics.

Aimed at supporting the implementation and progression of a mastery curriculum, this diagnostic approach (developed in New Zealand) is based on interview techniques and a structure of conceptual development. It will support practitioners in their understanding of the strategies to support learners in mathematics.

This fully funded programme is aimed at primary teachers, maths subject leaders and SENCOs.

The diagnostics interview programme was primarily developed for children who are struggling with maths and is therefore relevant for both KS1 and KS2.  However, Adam Gifford, the course facilitator suggests that the interview works best from the end of year 2 onwards and isn’t recommended for reception or year 1.

This is a two day programme and is split into the following parts:

  • Understanding the stages of the diagnostic interview for assessing children’s difficulties with maths
  • Practice – looking at a series of example interviews
  • The Interview in detail

“The whole course was engaging, interesting and really useful. I’m looking forward to sharing it with my maths team and implementing the Diagnostic tool in school next year.” – Kate Wilson, Deeplish Primary Academy

“I really enjoyed the whole course. I found it interesting and thought-provoking as well as it providing me with a really useful diagnostic tool. Adam was very engaging too.”Karen Burman, Smithy Bridge Primary School
