Council-led initiatives have been key to driving up education standards and giving Haringey one of the best school records in the country.

Cllr Elin Weston, cabinet member for children, education and families, said the council had made a concerted effort to support schools and help them work together – despite government cutbacks and a loss of local authority control over education.

It has helped Haringey to achieve one of the best records in the UK, becoming one of only five boroughs to have all schools rated good or outstanding by education watchdog Ofsted.

Five years ago, only around 60 per cent of the borough's schools were good or outstanding.

Haringey’s achievements come despite the fact that it has some of the highest levels of deprivation in the country – in 2015, it was ranked the 30th most deprived borough out of 326 English local authorities.

Cllr Weston said: “The most important thing for us is that it means every child attending a school in Haringey is benefiting from a really high standard of education, and that can make such a difference to their life chances in the future.

“Like every London borough, we have had a 0.5 per cent increase in the overall schools budget – but that in no way reflects the rising costs schools are facing.”

According to the Institute for Fiscal Studies, the amount of per pupil spending in England’s schools has fallen by eight per cent since 2010.

Cllr Weston said that while teachers and pupils were the main drivers of success, the council has done its best to raise standards.

She said: “There has been a real, sustained effort to support our schools and reach the highest standards we can.

“The starting point would have been the Outstanding for All commission. That created a number of recommendations on how schools might work together and support each other.

“We have a great schools improvement team within the council that has supported schools and challenged them on data, and tried to pick things up and support schools through challenges.”

Cllr Weston said: “We know there can be an issue in terms of attracting teachers to STEM [science, technology, education and maths] subjects, so we have set up a STEM commission.

“That is not only about being able to recruit good STEM teachers, but about having an excellent STEM offer to prepare them for the changing world of work and economy, so they can have the best jobs they can and a range of options available to them.”

Local authorities have lost control over education due to changes that have allowed schools to set up as academies and free schools.

The Government has also scrapped the education support grant, which funded council-led schools improvement projects.

But Cllr Weston said the council had tried to retain as much control as possible and encourage partnerships between different schools.

She said: “We have also recently set up Haringey Education Partnership.

“There is a lot of expertise in Haringey. It means that if there is a particular need for additional innovation in a particular subject area, a school might provide that support to another school.

“It might mean a member of teaching staff might go in and do some training; it might mean people go on secondments; any number of peer-to-peer support mechanisms.

“We do not want to lose our influence on schools in the borough.

“We will continue to promote high standards and school-to-school support to make sure we do everything we can to stay in this amazing position we have got to.”
