Amnesty International commissioned a comprehensive, evidence‐based, independent assessment of its Stop Violence against Women (SVAW) campaign. Two independent consultants were commissioned to carry out this review, and to provide Amnesty International with an objective and honest assessment of the campaign. The evaluation aimed to look for indications of Amnesty International’s contribution to changes in the external world, assess how the organization worked in partnership with women’s movements and networks, and to identify successes and areas for improvement at the operational level of the campaign. Because of the scale of the campaign, and the huge range of actions carried out by Amnesty International around the world over six years, a case study approach was agreed. Case studies were carried out in the UK, Kenya, Uganda and Venezuela.
