Studies in north-western Australia Aboriginal communities identified executive functioning and behavioural regulation as significant issues for children. Exposure to alcohol prenatally and adverse childhood experiences are known risk factors for impaired self-regulation and executive function, these risk factors being present in remote communities. In response, a partnership was initiated to trial a teacher-delivered self-regulation intervention based on the Alert Program®. While student outcomes were assessed, this paper describes the implementation and impact of the intervention on teachers through the five dimensions of the RE-AIM framework (Reach, Efficacy, Adoption, Implementation, Maintenance). Trained classroom teachers (n = 29) delivered eight Alert Program® lessons to students over 8- weeks. Impact and implementation outcomes were assessed through teacher training and student lesson attendance data, and pre-training and post-intervention teacher questionnaires. Data were analysed using paired-samples t-tests and descriptive statistics. Eighty-one to 100% of prescribed lessons were implemented and teacher understanding of self-regulation and the Alert Program® improved significantly following the intervention (n = 14, p = 0.001). Most teachers (88%) reported changing their teaching and behaviour management practices because of the intervention and agreed there were benefits in teaching the Alert Program® to students in a region with high reported rates of foetal alcohol spectrum disorder and self-regulation impairment.
