IELTS One Skill Retake: A Bias for Best Model

A transparent approach to communications and decision-making is central to policy adjustments such as this, in addition to involving stakeholders in the process (Jones & Saville, 2016; Chalhoub-Deville & O’Sullivan, 2020; Spiby & Clark, forthcoming 2023).

Both the implications of these changes and their relation to test consequences (Weir, 2005; Saville, 2009; Clark et al., forthcoming 2023) must be thoroughly investigated and recorded if they are to be understood by key stakeholders (Taylor, 2007).
