Schools should not get distracted by "marginal" issues like school meals, the head of Ofsted Sir Michael Wilshaw has said.
Pupils' uniforms and toilets were also considered "minor" problems, with standards of teaching and managing the behaviour of pupils deemed far more important.
Wilshaw said in an interview with LBC London Radio: "What is really important, and I can't stress this too much, is that governors have got to focus on the big issues and not the small ones.
"Governors have got to focus on quality of teaching at a school, ask the head teacher about progress of students and the outcomes of students. Is the culture of the school right? Is the behaviour good? Those are the big issues and those big issues we inspect as well."
