TWO more South Gloucestershire schools have been told they must improve by education watchdog Ofsted.

Chipping Sodbury School and Yate International Academy were both rated at level three by inspectors- a grade requiring improvement.

Only last week the Gazette reported that Marlwood School in Alveston had also been given the same rating after dropping one level from its previous assessment.

At Chipping Sodbury secondary, inspectors said the quality of teaching, the behaviour and safety of pupils and the leadership and management were all good but the achievement of pupils needed to be better.

Lead inspector Sean Thornton said: "Although progress is improving, achievement is not yet secure. In particular, students do not reach the standards of which they are capable in English."

He said boys did not do so well as girls and the achievement of pupils was variable between groups of students and in different subjects.

But good leadership and management were already leading to improvements, teaching was now good and there was an acceleration in progress by students.

There was also praise for "highly effective" governors, who had a good understanding of the school's strengths and areas for improvement.

Head teacher Gareth Millington said the Ofsted inspection had been "positive". Results were improving and recently introduced improvement measures were having a positive effect.

He also highlighted Ofsted's comment that his own commitment to further raising standards was shared by all staff.

Mr Millington said: "We had our best ever results last summer across the board and we were very pleased with our parents’ views about the school, which the Ofsted team said were among the best they had ever seen."

The team who inspected Yate International Academy said the achievement of pupils and the quality of teaching needed to be better but the behaviour and safety of pupils, along with the school's leadership and management, were good.

Lead inspector Simon Rowe said: "Although achievement has improved in both the primary and secondary phases , students do not yet make good progress in writing, mathematics and in the sixth form.

"While there is much good and outstanding teaching, too many lessons do not challenge all students sufficiently."

But he said leaders, managers and governors had raised expectations across the academy.

He said: "Students make good and outstanding progress in many areas, for example in humanities, English and in the reception class."

He also said the academy's primary phase had improved since the previous inspection and was now rated as good.

Dr Rob Gibson, the chief executive principal of the Ridings' Federation of Academies, said: "While the federation recognises that there continues to be room for improvement, I believe the report reflects well on our work in raising standards.

"Particularly pleasing is the recognition by Ofsted of the rising standards in our primary phase and the continued progress in the secondary phase."

Yate's principal, Roger Gilbert, said: "I am pleased that Ofsted recognised the progress our 3-19 academy has made, while much work has already commenced in addressing those areas identified for improvement."

He also said the academy had achieved a record haul of GCSE and BTEC results last year, with 58 per cent of students achieving at least five A*- C grades, including in English and maths - a nine per cent increase on 2012.
