Cheltenham Ladies' College has been classified as 'excellent' in every category, according to the latest Independent Schools Inspectorate (ISI) report.
In the report, when assessing the pupils' academic and other achievements, it said they 'develop a comprehensive body of knowledge, skills and understanding across all areas of learning, enabling them to continually extend their range of achievements.'
The key findings went on to state that the 'pupils' attitudes to learning are consistently positive', reporting that 'they show initiative, independence and leadership in their learning', and 'articulately communicate their ideas, views and feelings, listen attentively to others, read avidly and skilfully express themselves when writing or during discussion'.
In the area of pupils' personal development, the report said 'pupils develop strong confidence' allowing them to 'eagerly and resolutely seek new challenges in order to stretch their immediate and longer-term personal boundaries and aspirations.'
Principal Eve Jardine-Young said: "We are absolutely delighted that CLC is fully compliant with all regulatory requirements and has achieved the highest possible grading of 'excellent' in all areas in the Educational Quality inspection."
"My warmest thanks and congratulations go to all of our teachers, pupils, staff and parents for their contributions; without their dedication to sustaining excellence throughout College, this result would simply not be possible.
"It is a powerful affirmation of their incredible work."
