Involving students in peer review has substantial benefits for students' learning and development and, more pragmatically, for staff workload. This paper reports on a student-led effort to co-design a peer review formative assessment task. The assessment is part of a personal development module within a higher education degree apprenticeship programme delivered via blended mode by a business school in South-East England. This case study on student-staff partnership offers a description of the process and a reflection on the impacts from both the student and staff perspective. It suggests that student co-design and peer review activities complement work-based learning, effectively bringing the prior experiences and academic skills of mature/professional students into the classroom.
