About the data
Alongside their Annual Report (last published December 2015 using inspections data as of 31st August 2015), Ofsted produces various analysis to show Local Authority Performance. We wanted to provide similar analysis but base it on all of the very latest inspections, as of now, rather than as of August 2013. Below is a table that does just that and gets updated every night. Our data engineers have listed a few pointers to help to you make the most of this.
- Pupil counts are sourced from the January 2015 school census (specifically the Headcount of pupils column from the underlying data of SFR16/2015). This is rounded to the nearest 5 and an X is assumed to be 1 pupil. Where there is no school census headcount we fall back to the Number of Pupils value from EduBase. If neither of the previous are present we use the EduBase School Capacity figure.
- The list of schools as well as each school’s phase and region is sourced from EduBase as of October 2014. Only those marked as
Openat that date are included. No Children’s Centre inspections are included in this table.
- Watchsted is the source of the inspection grades data. Only a school’s latest inspection is considered. Where an academy is yet to be inspected it’s latest pre-conversion inspection grade is used.
- The latest framework option only shows inspections since 01/09/2012. This allows you to compare like for like inspections. Older frameworks reflect a different grading criteria, but both Ofsted and the DfE include the latest inspection for each school (regardless of the framework) in their calculations for their Good or Outstanding indicator.
- Schools which have not been inspected are ignored and not included in the denominator of any percentage calculation.
- There is an option to Hide LAs with fewer than 10 primary or 3 secondary school inspections. If an LA is hidden, it’s values still contribute to regional and national calculations.
