In the United Kingdom, the Coronavirus Act relaxed the duty on Local Authorities to provide all of the support set out in pupils' educational, health and care plans (EHCPs). They were expected to use 'reasonable endeavours' to deliver as much of this as possible. This relaxation was lifted in September 2020, meaning that from that point the legally required support stated in EHCPs should have been fully reinstated. In the first national lockdown most special providers reported they were only able to offer a very limited number of pupils in-school places. On average their capacity was 30% of their usual intake. In January 2021, the Prime Minister announced a further national lockdown, requiring educational settings to close to the majority of pupils for the second time. In this report this lockdown in early 2021 is referred as the second lockdown (although there was a national lockdown at the end of 2020, educational settings remained fully open). A briefing paper had been published setting out a summary of what happened during this second lockdown, and in the term following the expected 'return to normal' (i.e. all educational establishments being fully open as before the pandemic). This report provides all of the detail gathered to inform that paper. It is based on: (1) A survey of Headteachers from 190 special schools and colleges in England. This represents an 11% response rate across the sector; (2) Depth interviews with senior leaders of 40 special school or colleges; and (3) Depth interviews with 40 parents of children with EHCPs who attend this type of setting.
