Schools will be required to report how many children with Down syndrome they educate as part of a government commitment to improve opportunities.
Sir Liam Fox, Conservative MP, previously urged ministers to add it as a separate category to the school census.
There are currently 13 categories for SEND on the census, such as “moderate” or “severe” learning difficulties, but there isn’t one for Down syndrome specifically.
From January 2025, schools will be able to select the condition from the list.
