Education, support and research for early years autism

Our Team

Puzzle Centre adopts a team approach to working with the children who attend the sessions in the nursery – the expertise of the Teacher and Therapists is used to ensure that each child receives an appropriate input of language and a tailor made programme of teaching and therapy during the entire session. All staff work with children on a one to one basis as well as within group sessions led by the Teacher or Therapists. Learning Assistants receive regular training and guidance on teaching methods and approaches.
