Green Street Green Primary School has been demoted by Ofsted from outstanding to requiring improvement.

The mixed primary school in Orpington was judged to be requiring improvement in all five areas it was observed in - leadership and management, behaviour and safety of pupils, quality of teaching, achievement of pupils and early years provision.

Requiring improvement is one level above inadequate - the lowest rank awarded by the government watchdog.

This is the first inspection since the school converted to an academy in 2012, plummeting from their previous 2009 rating of outstanding - the highest available.

In particular, boys at the 441 pupil school were found to be at a disadvantage.

The report states: "Boys do not make as much progress as girls across the school. Gaps in achievement between boys and girls are too wide.

"Behaviour is not yet good. Where teaching does not interest boys or challenge them appropriately, they often lose concentration and waste time fidgeting.

"Teachers’ expectations of what pupils, especially boys, can achieve are sometimes too low."

The latest report, published on April 20, identified senior leaders are not holding teachers to account for the achievement of pupils, particularly boys.

Marking and feedback were an issue with "basic errors" in grammar, spelling and punctuation left uncorrected.

The quality of teaching is not consistently good, and skills of leaders in maths and English were found not to be developed enough to drive improvement.

But Ofsted did identify teaching in the speech and language unit matches pupils’ needs well.

Those with disabilities or special needs also achieve well, and pupils report that bullying is rare.

Ofsted highlighted steps the school needs to take to improve which include raising teachers’ expectation and challenging pupils, improving behaviour, and ensuring homework is regularly set and marked.

Governors are also required to develop their skills in holding senior leaders to account, and they in turn holding teachers accountable for the achievement of pupils.

Ofsted recommended an external review of governance, and how the pupil premium is spent, should be undertaken.

Headteacher David Abrahams, who has been in the post for two years, said: "Whilst we were disappointed with the grade we were given, the staff and governors have worked quickly to put an action plan together and we are now focused on moving the school back to at least good as quickly as possible."
