Schools use the questionnaire for different purposes. A discussion to explore what would be best for your specific situation is always welcome but options you might consider are:
Pupil voice collecting data about what students think about themselves and their school.
Evaluate the strengths and weaknesses of a school intervention and use statistical data to back up action points in SEF.
Address departmental differences within the school.
Shape group processes by sharing questionnaire outcomes during assemblies with whole Year groups.
Identify individual students' patterns during parents' evenings.
Encourage individual students to improve specific areas of their school life.
