Efforts to improve teaching in schools by using IT are being hampered by the number of teachers who are not able to use computers competently, according to school inspectors.
The Office For Standards in Education (Ofsted) warned that the use of IT to improve teaching is dependent on skilled individuals.
But it reported that, while the level of IT skills among teachers is improving, nearly one in 10 are still unable to use IT properly.
The inspectors also concluded that only a small number of schools are using IT to improve teaching across the curriculum.
Ofsted admitted that a National Lottery funded programme of in-service IT training for teachers was a "severe disappointment" and "did not take sufficient account of teachers' needs".
David Bell, HM chief inspector of schools, said that, while five years of government funding had enabled schools to increase the use of technology, there was still a long way to go.
"What the government, local education authorities and schools must now focus on is ensuring that the quality of pupils' IT experiences is consistent across all schools," he said.
