<jats:sec><jats:title>Background</jats:title><jats:p>Body image dissatisfaction during adolescence is common but not benign. School-based interventions have the potential for wide reach, but scalability of previous programmes is limited by a reliance on external facilitators.</jats:p></jats:sec><jats:sec><jats:title>Aims</jats:title><jats:p>To assess the acceptability, feasibility and efficacy of a teacher-delivered body image intervention.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>A pilot clustered randomised controlled trial in which 16 classes of adolescent girls were allocated to a 6-session body image programme (<jats:italic>n</jats:italic> = 261), or usual curriculum control (<jats:italic>n</jats:italic> = 187) (registration: ISRCTN42594993).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Students in the intervention group had significantly improved body esteem and self-esteem and reduced thin-ideal internalisation. Effects for body esteem and thin-ideal internalisation were maintained for 3 months. There were no group differences for eating pathology, peer factors or depression. Acceptability, feasibility and efficacy varied between schools.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Teacher-delivered body image lessons have promise but further work is needed to increase efficacy and make interventions suitable across a range of schools.</jats:p></jats:sec>
