The TWiTCH programme is based on the principles of Dialogic Reading. Through TWiTCH training, practitioners learn how to use a clearly structured intervention that builds on familiar Early Years practice (storytime and small group work) to improve the quality and quantity of adult-child interactions. The programme aims to strengthen practice and build practitioner skills and confidence, leading to regular, high-quality interactions which will increase vocabulary and the complexity of children’s language and their ability to express opinions.
