Education bosses have vowed to pull out all the stops to turn around a Southampton school after it was named the worst in the country in Government league tables published today.

Department for Education figures reveal that pupils at Oasis Academy Mayfield make less progress than at any other school in England.

It is also among the worst in the country for its attendance rates, the number of children who persistently miss lessons, and the proportion of teenagers leaving with five or more A* to C grades, including maths and English.

Last night bosses at the academy, its charity sponsor and Southampton City Council all promised they would continue work already underway to help it turn around its fortunes.

Oasis Mayfield was formed in 2008 following the controversial merger of Woolston and Grove Park secondary schools.

In 2009 it was named the ninth worst school in England measured by the results children achieve at the end of primary school and their GCSE grades, taking into account factors including pupils’ gender, mobility and levels of deprivation.

Last year’s GCSE results at the academy, where building work is underway at its site in The Grove to create a brand new school, dropped further.

Principal John Toland said the academy is working relentlessly in its “drive in raising aspirations and outcomes”

for pupils, and improving attendance rates – which are this year at 92 per cent – would help “significantly” boost results this year.

He said: “Our figure was affected by a high level of non-attendees and those who failed to complete courses through the time of transition.

This was reflected in our disappointing results last summer.

“We are confident that our robust structures and systems in monitoring and interventions have addressed these factors and we will see much improved achievement this summer.”

Southampton’s education chief, Cllr Paul Holmes, said: “While the scores from Mayfield are disappointing, we know that many of the systems at the academy have been much improved since last summer and we anticipate that this will have a positive impact on attainment and attendance.

“The role of the local authority is to support and challenge our schools and we will continue to do that where necessary so that all our schools are achieving the very highest standards.”
