This is the third in a series of five research briefs that explore the impact of Little Stars, story-based teacher training programme on language and early literacy in 4- and 5-year-olds. This brief focuses on whether resource-based teacher training led to take-up of the programme as intended, and the extent to which teaching practices changed through implementing the programme. We used Kirkpatrick’s model1 and focused on Level 3 (behavioural changes) to explore how teachers were using the programme and how the training translated into actual classroom practice.
