The Key invited a sample of its members to complete its annual survey in February 2017. The questionnaire for this study was designed by The Key and conducted online using Survey Monkey. 1,182 school leaders from mainstream schools completed the full survey.
The data has been weighted to match the population profile of schools in England in terms of region, school phase and school type. The profile of The Key’s membership database is similar to the profile of schools across England. The data can therefore be taken to represent the views of teachers on The Key’s database, which in turn provides an indication of the opinions of leaders in mainstream schools across England.
The survey was designed, administered and analysed by The Key. Ipsos MORI provided advice on questionnaire design and weighting.
