This entry examines the role digital technologies play in learner success, both as a factor that impacts on learner success and in the context of digital technology’s role in institutional initiatives and supports designed to enhance learner success. The common goal of learners and educational institutions is that a learner will achieve their educational goals within that institution. When a learner withdraws from the institution this represents a loss of opportunity for that individual to achieve those goals, a loss to the institution in terms of mission and income, as well as a loss to society with regard to the benefits that accrue from an educated populace. Where students do not exit the institution, but progress through a programme without achieving the success of which they are capable, this also represents a loss of potential for the individual, the institution, and society. Learner success is impacted by both learner characteristics and institutional structures and processes. Institutions can enhance learner success through strategic initiatives and the targeted deployment of effective learner supports (Thomas, Hill, O’Mahony, & Yorke, 2017). In most cases such initiatives and supports are mediated through digital technologies, as their use now permeates most forms of teaching and learning activity.
