Data analysis of your pupils' performance is a key part of understanding attainment and improving pupil outcomes. Get to grips with how to go about it, including what to focus on and how to analyse data from ASP and IDSR.

We worked with 3 of our associate education experts – David Driscoll, Brendan Hollyer and Ben White – to write this article.

Use these performance data tools and sources


There are various tools that allow you to analyse different performance data, such as:

  • Analyse School Performance (ASP) for headline measures
  • Inspection data summary report (IDSR) for 2019 and 2021 year group contextual information, and 2019 performance data
  • DfE school comparison tool to compare exam and test results with other schools
  • Local models for analysis, such as local authority (LA) or academy models
  • Purchased models linked to schemes of work


You can use data from:

  • National Foundation for Education Research (NFER) tests
  • Phonics tests
  • Practice tests and past papers
  • End of Key Stage (KS) SATs
  • Termly or end-of-unit internal summative data
  • Tests linked to purchased schemes of work
  • Pupil voice
  • Monitoring information from book looks, learning walks and subject scrutinies

These are the questions you should be asking whenever you're reviewing
