The school with the lowest GCSE results in Waltham Forest has been praised for making good progress, but told further improvements must be made.
Just 32 per cent of pupils at Kelmscott School in Markhouse Road, Walthamstow, achieved five good GCSEs or above last year and Ofsted inspectors criticised standards of teaching in English and maths.
In a letter sent by the watchdog to headteacher Lynne Parvez following a follow up inspection in March, inspectors said the foundations had been laid for reversing a decline.
Inspector Carmen Rodney said: “You and other senior leaders have been very open about the reasons for the decline in 2013 results in English.
“Your openness has contributed to a methodical review of English and mathematics before planning the next steps to accelerate improvement in these subjects.”
She said that the school’s plan of action “includes clear lines of responsibility, measurable targets and monitoring and evaluation.”
“The governing body, like the local authority, believe in and support the work you and your staff are doing to accelerate improvement,” the inspector added.
