Staff at a large Oxfordshire comprehensive need to spice up their lessons for unmotivated pupils and cater for the full range of pupils' abilities, a team of inspectors said.

Standards at Gosford Hill School, Kidlington, are rising, but there were still areas where teachers could improve, said the Ofsted team.

The attitudes of pupils indifferent to learning should be improved by making activities more motivating, the inspectors said.

It said pupils were not always clear about the purpose of a lesson and what teachers expected them to learn, and lesson planning did not always take into account the needs of pupils with different abilities. There was also a variation in how teachers implemented school policies, particularly on assessing pupils' learning and handling their behaviour.

But the standards of teaching were satisfactory or better in 90 per cent of the lessons.

GCSE results are above the national average and last year all the pupils gained at least one GCSE.

The school has successfully lifted the proportion of GCSE grades A* to C to above the national average.
