An Oxford primary has received a warning from Ofsted to improve significantly, after inspectors expressed concern at pupil under-achievement during a visit to the school.

Windmill Primary School in Headington was inspected by the schools' watchdog last month and issued with a notice to improve.

The report said that pupils in Year Six underachieved, and judged the school's overall effectiveness as inadequate.

Teaching, although satisfactory overall, was found to be inconsistent.

The report recognised that the school had the capacity to improve and that headteacher Lindsey Weimers had a clear view of what needed to be done.

Inspectors praised the "warm and secure environment" of the reception classes, which they said helped children settle well into school life.

They also highlighted the good care and support for vulnerable pupils and the fact that children enjoyed school.

The report said: "The headteacher has a clear view of what needs to be done and has set the right priorities for the school's future.

"She has recognised the root causes of underachievement in Year Six and is taking effective action to make improvements.

"Teaching is now satisfactory overall and beginning to help to raise pupils' achievement. However, the school is aware that it needs to increase the quantity and consistency of good teaching in order to address the legacy of inadequate teaching."

To improve further, the school was told to raise standards for pupils in Years Three to Six, improve the quality of teaching and ensure subject leaders are effective in their roles.

Inspectors will visit the school again during the next year to monitor progress.

Mrs Weimers and chairman of governors Tim Spiers said they were pleased that Ofsted had agreed with their own assessment of the school.

Mr Spiers said: "We are pleased that the report reflected our own view of the school, and we are confident that we are improving. We were particularly pleased that the inspectors recognised that our children enjoy school and have a good sense of community responsibility."

In March, Ofsted served similar notices on Rose Hill Primary School, Oxford, and St Leonard's Primary School, in Banbury.
