A Working on What Works (WOWW) approach was utilised over six sessions in a mainstream Scottish primary class to enhance classroom relationships and behaviours. The aim of the intervention was to manage everyday classroom problems within a natural classroom environment. WOWW incorporates positive psychology and implements a solution-focused approach. The quantitative results illustrated an improvement in the teacher ratings and class ratings for the class goals set by the class teacher, and helped the teacher to feel more confident in her class. From the qualitative comments, class teacher and pupils reported a positive experience of WOWW and noticed a difference within the classroom. In summary, WOWW influenced a positive change to relationships and behaviour within the classroom.
