Broughton Jewish Primary School is appealing against its latest Ofsted inspection findings, claiming the inspector's report contained inaccuracies which led to a downgrading to "requires improvement".

In a letter to parents, the school said it had implemented an improvement regime 18 months before the inspection, and would hold an open day to explain its position."In our opinion the draft report contained a number of inaccuracies based on certain findings which we strongly disagree with," governors chair Dov Black wrote.

Two years ago, BJPS was judged a "good" school by Ofsted. "Requires improvement" has replaced "satisfactory" under tougher inspection rules. Now a school's overall effectiveness is assessed by Ofsted in four areas - teaching, pupil results, behaviour and leadership. If just one area "requires improvement", the assessment is downgraded.

The Ofsted inspectorate has classified the complaint under "exceptional circumstances" and has not published the inspection report.

Broughton Jewish has seen a major rise in intake over the past three years, up 100 pupils to 447.

It has applied for grant funding to increase its capacity.
