A think tank has called for Ofsed inspections to be scrapped in a bid to stop a "toxic" target-driven culture in schools.
A study from Demos suggests that parents, teachers and pupils, as well as inspectors, should be responsible for drawing up annual school reports.
It argues that the current system, where schools are held to account through inspections and league tables, is "profoundly toxic" and fails to improve standards.
It said that the current culture forces headteachers and teachers to put results and targets ahead of pupils' education.
