TWO schools have criticised new Government performance measures after they came towards the bottom of national league tables.

Wexham School, in Norway Drive, Slough and Altwood CoE Secondary School in Altwood Road, Maidenhead, both hit back at the new Progress and Attainment 8 scores released by the Department for Education last week.

Wexham and Altwood were placed in the bottom 12 per cent of all secondary schools nationally – with a ‘well below average’ rating – but in their most recent Ofsted inspections were rated as ‘good’.

The new league tables compare schools through the new ‘Progress 8’ rating, which measures how much students improve over time, and the ‘Attainment 8’ score, which measures their raw exam results. The league tables have now been released online. They do not include special schools.

Lawrence Smith, head of Wexham School, said: “Progress 8 is just one factor used to measure schools and neglects certain pupil characteristics, which may be “unfair to some schools” and is to ours.

“This is well documented in research.”

Rated as the worst performing secondary in the Royal Borough, Altwood said in a statement: “In our recent Ofsted inspection, dated October 2017, we were judged as good in all areas.

“Under the new measurements, we are one of a few schools that are improving rapidly but find themselves categorised as underperforming.”

Out of Slough’s primary schools, Claycots School in Monksfield Way, was also judged to be ‘well below average’ in regards to progress with reading and maths, although it was rated ‘above average’ for writing. It has also received a good rating from Ofsted in its recent inspection.

Meanwhile, Marish Primary School in Swabey Road was rated the best primary school in Slough, receiving a ‘well above average’ rating for student progress in reading, writing, and maths.

Headteacher Gill Denham said: “This is an exceptional achievement. Children and staff, parents and governors, have worked tirelessly together to shape an ethos that enables everyone to exceed expectations.”

Upton Court Grammar school was judged to be the best performing secondary school in regards to student progress, with 98 per cent of pupils achieving grade five or above in English and Maths GCSEs.

The worst performing primary school in the Royal Borough was Riverside Primary and Nursery in Cookham Road, Maidenhead. It has received a ‘good’ from Ofsted in its most recent inspection.

The best performing primary school in the Royal Borough was Lowbrook Academy in The Fairway, Maidenhead. The school was rated ‘well above average’ in all categories.

The best secondary is Newlands Girls’ School in Farm Road, Maidenhead, the only secondary in the borough to have a ‘well above average’ score.

Across the South Bucks region, the worst performing primary school was Iver Village Junior School in High Street, while the worst secondary was Burnham Park Academy in Opendale Road. Iver Village is rated ‘Good’, while Burnham Park Academy is ‘Inadequate’, according to Ofsted.

The best primary in South Bucks was St Peter’s CoE school in Minniecroft Road, Burnham, while the best secondary was Khalsa Secondary Academy in Hollybush Hill, Stoke Poges.
