Helena Romanes School and Sixth Form Centre in Great Dunmow has been graded Good after an inspection by Ofsted.

The report said A-level achievements were above average, the teaching was “enthusiastic and engaging”, and headteacher Simon Knight was “highly visible and approachable”.

Inspectors said teaching had particular emphasis on providing challenge for all pupils, including the most able.

They added the school had made a “sharp improvement in results in 2015”. There was strong evidence of a positive transformation in the sixth form.

The report also said: “The progress of current learners shows continual improvement in A-level subjects and is now above average.”

It added that students on vocational courses also continued to make excellent progress and their attainments were high.

Assessing pupils’ demeanour, it said: “Behaviour in lessons and around the school is very positive. Pupils move around the school in a calm, orderly and purposeful manner and show mutual respect for their peers and adults. They are welcoming and friendly and proud of their school.”

The inspection found that the school’s rewards policy was effective and said pupils excitedly explained the benefits of working hard and making good progress.

“Pupils are enthusiastic about the opportunities the school offers them in terms of extra-curricular activities.”

It said: “Pupils, parents and carers feel that safety is well managed and is supported by clear rules and responsibilities, good relationships and positive behaviour.”

Mr Knight said: “I am very pleased the inspectors recognised the school’s continuing progress made since the last inspection in 2012. I would like to thank students, parents, staff and governors for their support in helping the school to achieve this outcome.”
