The two Bristol schools that switched from the private sector last year to become state-funded academies have both been found to be making good progress towards raising standards.

Bristol Cathedral Choir School and Colston's Girls' School have had "monitoring inspections" from learning watchdog Ofsted.

Each has been found to be adapting well to the change from being selective fee-charging schools to being oversubscribed maintained schools.

In both cases, the change has meant much larger pupil numbers in the lower year groups. Work is due to start on new buildings next year to help the academies accommodate the eventual much higher numbers on roll.

"The transition to academy status has been managed well and morale is high," the BCCS report says.

"The academy has made a very good start at setting up a robust infrastructure that will support future developments."

The inspectors' other findings were as follows:

Bristol Cathedral Choir School:

Standards are high, with every student in Year 11 achieving five A*-C grades at GCSE;

Students are "polite, friendly and helpful";

Principal Neil Blundell, who joined a year ago, provides "very clear direction and drive";

Areas for improvement: more extensive systems to track and monitor academic progress and students' learning to be checked more carefully during lessons.

Mr Blundell said: "This is a very positive report after our first year as an academy. Since we were moving from the independent into the state sector, a tremendous amount of change has been necessary, so I am particularly pleased that the inspectors recognise that we have made good progress but have taken the changes at a sensible pace."

Colston's Girls' School:

Standards are high, with every student in Year 11 achieving five A*-C grades at GCSE;

Atmosphere in the school "happy, welcoming and very calm";

Plans in place to adjust the curriculum to match the needs and aspirations of a changing academy community;

Areas for improvement: use expertise and rigorous analysis to ensure that every student makes good or better progress, and maximise opportunities for all students to contribute to the academy and wider community.

Principal Lesley Ann Jones, who led the school through the transition, said: "The report was very positive. It confirmed that standards remain high and gave us the opportunity to reflect and to seek further improvements."
