Harvey Road School in Croxley Green has been rated “outstanding” by the schools inspectorate.
The school, in Harvey Road, was inspected by Ofsted in October and judged to be outstanding.
The report highlights “substantial curriculum changes which have contributed effectively to pupils’ progress and the continued rise in standards.”
Nick Rowlands, headteacher, said: “The school’s success is based on a very powerful and hugely effective partnership between staff, pupils, parents and governors.
“The children play a significant part in driving forward new ambitious ideas while the staff are totally committed to the school’s vision of: ‘Be happy, Show Respect and Seek Success’.
“Not only are the standards of attainment and progress over the past six years exceptionally high but the extended opportunities in sports, music and languages are excellent.
“We offer children exceptionally well focused initiatives that are rigorous and purposeful whilst maintaining the sense of enjoyment and awe that is so important in young people.”
The report praised pupils' “outstanding behaviour and sensitivity to others supports the school’s caring ethos.”
Reverend Miriam Mugan, chair of governors, added: “As Governors we are delighted with the result of the OFSTED inspection and we will continue to work with the Headteacher and school staff to maintain and further improve the learning experience and opportunities for the children of Harvey Road School.”
