Barnsley has the worst performing secondary schools in the country, according to Ofsted's annual report.
Figures published this week by the government's schools inspector showed just 20 per cent of Barnsley's pupils attend secondary schools judged 'good or outstanding' by Ofsted.
However, secondary level performance strongly contrasts with primary schools in the town, with 62 per cent of pupils going to a 'good or outstanding' primary.
The authority's low rating comes despite a multi-million pound Building Schools for the Future project which has seen every secondary in the town rebuilt.
Coun Tim Cheetham said Barnsley Council is confident measures put in place will lead to improved outcomes for children in Barnsley.
"Whilst sharing the concerns expressed in relation to secondary schools, we also note the significant and sustained improvement in Early Years provision and primary schools," he said.
"The Department for Education recently acknowledged these achievements and confirmed the local authority has taken swift and decisive action to redress the situation in secondary schools."
A council spokesman said data used in the Ofsted report is 'out of date', and currently 25 per cent of secondary schools are judged 'good or outstanding'.
But that would still mean Barnsley ranks worst, with
Bradford at 28 per cent.
To drive up standards and transform the quality of education, learning and skills in areas like Barnsley, Ofsted's chief inspector Sir Michael Wilshaw has appointed a new regional director for Yorkshire and Humber, Nick Hudson, who will take up the post in January.
