Each survey is based on a sample of around 500 schools, selected using probability methods. All schools in the country with pupils in the target age range are eligible, including state-maintained and independent schools.

In each school, a sample of pupils is selected randomly from all classes in Years 7 to 11. All eligible pupils have an equal chance of being selected.

The survey is administered by NatCen interviewers in order to guarantee confidentiality to participants. No member of school staff is allowed to see the completed questionnaires and individual responses cannot be linked to any individual or school.
