This study evaluated the effects of a reading and language intervention, for low-income children living in a remote Chilean community, using a randomized controlled trial. At the beginning of the study, participants were allocated to the intervention (n = 34) or waiting control (n = 34) minimizing on a composite language measure and age. Children in the intervention group received a 27-week program aimed at fostering code-related, word reading and oral language skills. Children’s progress in language and literacy was monitored at four time points: pre-, mid- post-intervention, and at delayed follow-up 9-months after the intervention had ceased. At the end of the intervention, children in the intervention group scored showed improvements compared to the waiting group on pre-literacy, reading, language, and reading comprehension measures (effect sizes d >.25). The gains in pre-literacy skills, word reading and word knowledge were maintained at 9-month delayed follow-up, though the improvements in language and reading comprehension were not. Intervention programs designed to support literacy and language skills in remote communities can be delivered successfully by trained assistants. Our findings inform the future provision of language and literacy programs in populations living in isolated areas.
