The aims were to examine when, where, how and why the Holocaust is taught in state-maintained secondary schools in England, and to inform the design and delivery of a continuing professional development (CPD) programme for teachers who teach about the Holocaust. A two-phase mixed methodology was employed. This comprised an online survey which was completed by 2,108 respondents and follow-up interviews with 68 teachers in 24 different schools throughout England. The research reveals that teachers adopt a diverse set of approaches to this challenging and complex subject. In the report, teachers’ perceptions, perspectives and practice are presented and a range of challenges and issues encountered by teachers across the country are explicitly identified. The research shows that, although most teachers believe that it is important to teach about the Holocaust, very few have received specialist professional development in this area. It also shows that many teachers find it a difficult and complicated subject to teach, and that they both want and need support to better equip them to teach about the Holocaust effectively.(By the author)
