Establishing a DEI curriculum is a three to five-year process. This session will provide a roadmap of what this might look like. Diversifying the curriculum can often lead to a "knowledge-rich" curriculum, which is encouraged by Ofsted. However, a conscientiously designed DEI curriculum must acknowledge the challenges to pedagogy itself and cannot fast-track a resources-based or content-led approach, as this could result in bolt-on change rather than cultural change. To secure the future success of every student and sustainable staff training and development for diversity, equality, and inclusion, we need to create a culture of belonging in every classroom. This session will provide a practical roadmap for how heads of departments and CPD leads can embed a sustainable, long-term approach to belonging, representation, and success for every student across their curriculum areas. The session will cover belonging and culture in the classroom, including what this can look like and how this can be achieved, as well as how to diversify the KS3 curriculum for every student, including data analysis, pastoral care, and sustainable change. The session will also confront some of the discomfort and barriers that staff may face from each other and parents and how these can be overcome, including with practical examples of language/management approaches. Colleagues will leave the session with practical and actionable items that can be put to work at your next CPD and department meeting.
