Dr Green told the city's education committee: "If we expect more, we will get more from pupils and parents."
Dr Green found support from Chris Mason of the Liberal Democrats, who urged the directorate to examine the reasons why schools in the west end of the city were doing far worse than neighbouring schools in East Dunbartonshire. "The parental aspirations are pretty much the same but the attainments are very different," Mr Mason said.
Ken Corsar, Glasgow's education director, challenged assumptions that Glasgow schools were bottom of the league tables. "When we analyse schools like for like, our schools are not underperforming," Mr Corsar insisted.
Free school meal entitlement was around 25 per cent in some west end schools.
