PISA 2018 data

The request was successful.

Dear Department for Education,

The PISA 2018 report for England (https://assets.publishing.service.gov.uk...) included the following paragraph:

“As the figures did not fully meet the PISA 2018 participation requirements, a nonresponse bias analysis was required to examine whether the final set of participating schools were representative of the overall sample of schools and ensure that no significant differences were found between the balance of stratification variables in the achieved sample and the original, planned sample. The OECD’s Technical Advisory Group was satisfied that this analysis demonstrated that no notable bias would result from the non-response. The OECD therefore agreed that the UK data should be included as fully comparable to other countries’ data in the international reports.”

Could you please supply me with a copy of the non-response bias analysis that was sent to the OECD?

In addition, I was wondering if you could provide me with the following basic additional information:
• The GCSE mathematics grade distribution of the English pupils who completed the PISA 2018 assessment. (I.e. the *weighted* percent of the PISA 2018 participants in England that achieved an A* in GCSE mathematics, the percent who achieved an A etc).
• The GCSE English language grade distribution of pupils in England who completed the PISA 2018 assessment.
• The average progress 8 and attainment 8 scores of pupils in England who completed the PISA 2018 assessment.

Best wishes

Professor John Jerrim
