Ofsted inspectors say Spalding Primary School “requires improvement” and found the quality of teaching varying widely from “outstanding” to “inadequate”.
Inspectors visited the school from September 26-27.
Only one aspect of the school – the behaviour and safety of pupils – merited a “good”.
The school’s last inspection in 2009 found the school labelled “satisfactory” overall.
“Requires improvement” is the new name for the level of attainment formerly labelled as “satisfactory” so the report shows the school hasn’t managed over the last three years to climb the ladder into Ofsted’s good books.
But chairman of governors Paul Sharman says he is confident the school will make better progress.
He said: “We are confident we can move the school forward to make the necessary improvements. We know we have to improve and there are areas of good practice which we can build on.
“The Ofsted judgement is the equivalent of ‘satisfactory’ under the previous criteria so this rating can be misleading.
“With the support of staff, governors, parents and pupils, the school can make good progress towards the next Ofsted inspection.”
