A qualified teacher in a school or maintained nursery school who has responsibility for co-ordinating SEN provision. In a small school, the headteacher or deputy may take on this role. In larger schools there may be a team of SENCOs. Other early years settings in group provision arrangements are expected to identify an individual to perform the role of SENCO and childminders are encouraged to do so, possibly sharing the role between them where they are registered with an agency.
