MAT Insight - Understanding Your MAT Report (Free)

We’ve built a new free report for every MAT in the country! Our new Understanding your MAT Report allows you to see your trust in a new light.

What does the report contain?

The report brings together key measures like your schools’ ASP performance statistics, alongside your MAT’s size and local demographics, to help you understand the unique makeup of your trust compared to others in England. 

You’ll have the metrics and benchmarks at your fingertips to see your MAT’s specific strengths and challenges, without waiting on spreadsheets or trawling online tables.

  • Your schools’ DfE performance data, benchmarked against each other and the national average
  • GIAS (Get Information About Schools) data to understand your MAT’s size and growth relative to other trusts
  • ONS area classifications to see the demographic spread across schools in your trust

What can I do with the report?

  • We hope the report will help you shape smart strategy and find new ways to improve results for staff and students
  • The report is easy to read with clear, visual charts, so it’s perfect to share with your key stakeholders in your next strategy meeting
  • We’ve built the report in partnership with the Centre for Education and Youth (CFEY) and there is a special article by CFEY’s Loic Mendes “Breaking the link? Attainment, Poverty and Rural schools” looking at the relationship between deprivation and attainment. This could spark some interesting discussions about the demographics across your trust

FAQ on data used in the report

How did you get this data for my schools?
  • ASP: Arbor is an accredited supplier of ASP data. We achieved accreditation through a tender with the Department for Education which means Arbor receives secure, early access to school performance data. 
  • GIAS/ONS: The Get Information About Schools (GIAS) site is public, as is the ONS website. We scraped data from both sources and used it to, for example, map Area Type Classifications onto the geographical location of your schools. 

We use all of this data to provide schools and trusts with intuitive reports and dashboards to help them understand performance and plan self-improvement strategies. Over 10,000 schools and 300 trusts have used our service over the past 4 years!

What data are you using in the report?

We use a few different data sources in your Understanding Your MAT Report: Get Information About Schools (GIAS), Analyse School Performance (ASP) and ONS Area Classification data. 

We’ve used the most recent data we could find for your trust, which differed between ASP and GIAS. Where we’ve used ASP data, only schools officially part of your trust before 1st September 2018 are shown because the data set looks at that cohort’s results in 2019 summer exams. Where we use GIAS data, we've included all schools in your trust as of 1st September 2019 (the last time we imported GIAS data). We've explained which data source is being used on each page in the footnotes. 

This is why, if schools officially joined your trust after 1st September 2018, you may see some graphs in the About Your MAT section of the report showing more of your schools than in the Your Schools’ Performance section.

  • Free School Meal pupils: We took this data from GIAS. This shows whether a pupil's family have claimed eligibility for free school meals as reported in the annual spring school census. Parents are able to claim free school meals if they receive a qualifying benefit. This does not show pupils who actually received free school meals but those who are eligible to receive them.
  • SEN: This data was derived from ASP data and this measure shows all SEN support, SEN statement and EHC pupils.
  • EAL: This is derived from ASP data and looks at any student where English is not, or not believed to be, their first language.
  • Pupil numbers: For Arbor MIS schools, pupil numbers are derived from their MIS. For all other trusts, pupil numbers are taken from GIAS.
How did you calculate the national/MAT average?

About your MAT section - Using GIAS (Get Information about Schools), we brought together data on the rate of growth and size of all MATs with two or more schools to create three-year trends and calculate the national average of all academies in England.

Pupil characteristics (FSM) - Your trust average is the average of your schools’ proportion of FSM pupils. The national MAT average is the average of every academy in England’s percentage of FSM pupils.

Pupil characteristics (proportion of SEN and EAL) - Your trust average is the weighted average of your schools’ proportion of SEN/EAL pupils. The national MAT average is the weighted average of every academy in England’s percentage of SEN/EAL pupils. The averages are weighted by pupil number. 

Performance measures - Your trust average is the weighted average of all your schools’ results. The national average is the weighted average of all state schools in England, and the national MAT average is the weighted average of all academies in England. The averages are weighted by pupil number.

How does the colour coding and benchmarking work?

When your trust is benchmarked against other trusts in England:

  • A green bar represents your trust
  • A grey bar represents other trusts in England

The number of similar trusts to yours is determined by the number of trusts that are in the same range as your trust. For example, on page 10, size by number of schools if your trust has 4 schools, you will be a similar size to trusts that are in your range of 2-5 schools as it shows on the x-axis.

When your schools’ performance is benchmarked against the national average:

  • A green bar means the schools have performed above the national average on this measure
  • A yellow bar means the schools have performed close to the national average on this measure (this may warrant further investigation)
  • An orange bar means the schools have underperformed relative to the national average on this measure (warranting further investigation)

In the performance section, if your school(s) performance is in the same x-axis range on the graph as the national average then the bar will be yellow, if your school(s) performance is in a higher range on the graph then it will be green and if your school(s) performance is within a lower range on the graph then the bar will be orange. 

For the blend of phases graph, you will have a predominant phase if you have a difference of 2 or more schools in one phase. You will have a similar number of schools in phases if there is a difference of up to 1 school in those phases.




If you're having trouble accessing the report, here are some troubleshooting tips:

  • If you have a different role, just ask one of your colleagues to download the report and share it with you outside of Arbor.
  • Make sure you’re using an up to date browser (we recommend Google Chrome).
  • If you get an error message when trying to download the report, try logging into an ingognito window. If the error message appears again, copy and paste the error message ID into an email to so we can find out what the exact problem is.
  • If you can’t see your report under My Reports, it could be that we were not able to create a report for your MAT because we couldn’t find enough data about your schools from our data sources. If all of your schools joined the trust after 1st September 2019, we won’t have been able to build your report as this release looks at data from the academic year 2018/19. You can still use your free performance dashboards to drill down into your schools’ performance and download your schools individual Insight reports.
