Abstract

Background: Oral language skills provide the foundation for formal education, and children may require language support over an extended period of time to maximise their education potential. Most work on language intervention, however, has focussed on the preschool or early school years. Here, we describe the development and evaluation of the Oral Language for Literacy Intervention (OLLI) programme which is designed to support children with weak language skills in the later primary school years. Methods: We conducted a randomised control trial in 33 schools (50 classrooms). The language skills of all 8–9 year‐old children in each participating classroom (n = 1,423) were assessed using an automated app (LanguageScreen). The six children with the weakest LanguageScreen scores within each classroom (n = 296) were randomly allocated to the intervention (n = 148) or control group (n = 148). The children in the intervention group received the OLLI programme delivered in individual and small group sessions over 20 weeks. Children in the control group received their typical teaching. Results: Children receiving the OLLI programme made significantly larger gains than children in the control group on a preregistered latent variable reflecting standardised measures of oral language ability (d = 0.38) and on a measure of their written expression (d = 0.42). Conclusions: These findings have important implications for improving educational attainment in children in the late primary school years. The OLLI programme is designed to be deliverable at scale and is of relatively low cost.
