Secondary school performance tables in England (2018)

The Department for Education (DfE) has published the achievements of pupils at key stage four (KS4) and how they compare with other schools in their local authority area and in England. The secondary school performance tables show:

  • Attainment results for pupils at the end of key stage four
  • The progress made by pupils between the end of primary school to the end of secondary school
  • Data on the performance of disadvantaged pupils
  • Differences in the performance of:
    • pupils who had low attainment at the end of primary school
    • pupils who had high attainment at the end of primary school
    • pupils who were at the expected level at the end of primary school. 

There is also data about school:

  • income and expenditure
  • workforce
  • pupil characteristics
  • pupil absence
  • Ofsted inspections. 

The DfE will publish updated figures, accounting for amendments made after November 2018, in April 2019.

Information on secondary accountability measures (including Progress 8 and Attainment 8)

Information and guidance have been made available on secondary accountability measures. The guidance on this page explains how secondary accountability measures have been calculated in 2017. It also gives more information about recently announced reforms that will apply to accountability measures in 2018 and 2019, and a short video explaining Progress 8 is available. The documents available on this page include:


16 to 18 accountability headline measures

The DfE has published information for schools on new measures in the 2017 to 2018 performance tables. The five new headline measures in the performance tables covering 16 to 18 education in 2017 and 2018 are:

  • progress
  • attainment
  • progress in English and maths
  • retention
  • destinations. 

The technical guide explains how the headline measures are calculated. Guidance for previous years is available on the UK Government Archive.

Guidance has also been published on progress scores for 16-18, which outlines how progress 'bandings' are calculated, and what the progress scores show. There is further information about 16 to 18 progress score bandings in the school and college performance tables.

Discounting and early entry guidance

The DfE has published guidance on approved key stage 4 qualifications, discount codes and point scores for reporting in the 2014 to 2021 school and college performance tables.

The DfE uses discount codes to group qualifications with similar content together in the school performance tables. This is so that schools are not credited twice for 2 similar qualifications.

Point score values are given to all qualifications in the school performance tables so that it's possible to compare qualifications of a different level, size and grading system. Excel spreadsheets containing further information on performance points and discount codes are available here.

Further guidance about calculating performance points is available online here.

Ready reckoners and transition matrices


The DfE has published key stage 4 pupil and school ready reckoners on revised 2018 data. Adjusting of extremely negative scores has been built into the Progress 8 pupil ready reckoner for the first time, whereby extreme negative progress scores are replaced with a minimum score that has been set for the relevant prior attainment group. While pupils still receive a large negative score, adjusting scores in this way helps to limit the impact of extremely negative individual scores on a school’s overall score. 

Transition Matrices have also been published for KS4 on revised 2018 data. In addition to the usual breakdowns for gender and disadvantage, the KS4 TMs have also been produced with breakdowns for special educational needs (SEN) and English as an additional language (EAL). The products were adjusted considerably to accommodate subjects moving from the A*-G to the 9-1 grading structure, and to include the first double award subject, GCSE combined science, on the 9-9 to 1-1 grading structure. These products allow users to select pupil number and percentage data by subject and KS4 attainment category for different KS2 attainment groups using built in drop down menus. This functionality improves the user experience, and makes the product smaller and much easier to use.  


The DfE has published a ready reckoner to calculate level three value-added scores and transition matrices of level three results by key stage four prior attainment.

Level three value-added is a progress measure for school sixth forms and colleges that is used in the 16 to 18 performance tables. You can also read the 16 to 18 accountability technical guide to learn more about the level three value-added measure.
