A Mildenhall primary school has been told by government inspectors that it must improve.
The former St Mary’s Church of England school, which converted to an academy in September 2011, was inspected by Ofsted in July.
It now has 417 pupils having grown in size since its conversion and the behaviour and safety of the pupils was rated as good by lead inspector David Turner.
However he said that the rate at which pupils progressed academically varied too much across the school and that they did not make consistent progress in different subjects, particularly writing, because teaching had not been “sufficiently challenging” or met the needs of all pupils.
Mr Turner said the quality of teaching at the school needed to improve as it had been more effective in Key Stage 1 than in Key Stage 2.
“In some lessons, pupils fail to make good progress because teaching is not challenging enough. Work and activities do not meet their needs and abilities, especially the higher ability pupils,” said Mr Leader.
He said the marking of pupils’ work was inconsistent and varied in effectiveness.
But the report said in stronger lessons teachers often used “highly imaginative techniques” to capture students’ interest.
“A good example was an outsatnding religious education lesson where children used everyday objects to discuss the themes of pilgrimage,” he said.
Pupils were praised for their behaviour and good manners and Mr Leader said they felt “safe and well-supported in the event of any problems.”
“They believe bullying is very rare and when it does happen it is dealt with quickly and their teachers help them to put relationships right,” said the report.
It said attendance was above average because of the positive way it was “encouraged, celebrated and checked upon by staff.”
Parents and staff were said to be highly supportive of the academy.
