This article highlights the changing role of special educational needs co-ordinators (SENCos) in England. SENCos are now required to manage change strategically and deliver inclusive school cultures. A school-based evaluative study undertaken by a teacher who is studying for the postgraduate National Award for SEN Co-ordination (NASENCO) for SENCos is featured within the article to illustrate the principles and techniques associated with strategic change management. The study is framed by a commentary that also includes references to more critical treatments of the shift towards quantified performance assessment, monitoring and management (of pupils, teachers and schools) which has been read as a displacement of professional judgement-based teaching practice.
