During October Planning Committee, plans were approved for the creation of 'Treetops 2' School in Grays.
The development of a new single-storey building will see the school offer an additional 140 school spaces to pupils aged between 3 and 19 who experience moderate learning difficulties. The school operates a special verbal behaviour (VB) department for children on the autistic spectrum as well as applied behaviour analysis (ABA), which is the science of human behaviour.
Cabinet also committed £1m investment in the local road infrastructure, which will help alleviate potential traffic issues.
Cllr James Halden, Cabinet member for education and health, said: "I'm thrilled that our plans for expanding Treetops School have been approved, meaning we can further expand our offering of education to those with special education needs in the borough.
"Treetops is one of Thurrock's strongest performing special educational needs (SEN) schools, with regular 'Outstanding' ratings from Ofsted and strong performance across key performance indicators year-on-year.
"Due to the specialist nature of the school, 'Treetops 2' will deliver a higher staff-to-pupil ratio, meaning we can offer even stronger support to some of our most vulnerable children. I look forward to seeing the plans come to life as work continues to progress, ensuring that we continue to provide a strong foundation for education here in Thurrock."
