The aim of this project is to evaluate whether Beanstalk's 'Story Starters' intervention is effective in boosting vocabulary and grammatical development in young children. Story Starters is a reading intervention delivered by Beanstalk, a national children's literacy charity committed to ensuring no child faces the severe consequences of illiteracy. Beanstalk trains volunteers to provide caring and fun one-to-one support to disadvantaged children aged 3 and 4 in local nurseries, aiding their language development.
