 annotated forms from the interviews with the practitioners to seek data consumers’ views on the data items practitioners identified as unhelpful. Phase 3: Missing Chapters project - Interviews with young people by project workers Phase 3 of the research, conducted only in the lead LA, took the form of peer research. This is a participatory method in which people with lived experience of the issue being studied take part in directing and conducting the research (Yang and Dibb, 2020). It aims to empower people to affect positive change by participating in research on their own communities (Lushey, 2017; O’Brien and Doyle, 2023). Three project workers were recruited by the lead LA to lead this phase of the research. All three were care leavers, meaning that they have a lived experience of being in the care system. The project workers collaborated with the Children in Care Council (CiCC) to enable the voices of children and young people directly impacted by recording practices to be heard. The three project workers were provided with an intensive two-day research skills training programme with the academic researchers from ARU. Additional training and continuous support were also provided by members of the Involvement team at the lead LA to prepare them for undertaking qualitative research with children and young people. ARU researchers supported the project workers in the data analysis aspect of the work with a further session to guide and model the process of coding data and developing themes. Two of the project workers, alongside other members of the CSC team, conducted face-to-face semi- structured qualitative interviews with young people in care (Yang and Dibb,2020) which focused on their knowledge and understanding of the information collected and recorded about them
