A junior school deemed “inadequate” has been making significant improvements, Ofsted inspectors said.
Normanton Junior School on Church Lane was given the worst possible rating in June 2013 and was criticised for having a poor standard of teaching.
Inspectors found most pupils started school with standards of attainment above the national average but it fell below average by the time they left in year six.
They also said the staff were too inexperienced and any action to improve teaching by the school’s leaders had been ineffective.
Inspector Anne Bowyer’s follow-up visit to the school last month found it had made significant progress.
She said: “The school has turned a corner at last.
“The actions leaders have taken over the last two terms, in particular, are bearing fruit despite the significant changes to staffing.
“This has been brought about by the determined leadership of the acting headteacher who has built up positive relationships with pupils, staff and parents and pulled the school together in a way not seen before.”
Mrs Bowyer also said the standard of teaching had improved.
She said: “Inadequate teaching has been eradicated and there is a small proportion of teaching that is good.
“These improvements are very recent, so the school needs more time to show that this improvement is sustainable and can be built upon.”
Since the school was found to be failing by Ofsted, six teachers have left and five new members of staff have been appointed.
The school is planning on becoming an academy, as part of a multi-academy trust which includes Walton Primary Academy and Normanton Common Primary School.
