Student persistence can be defined as the continuation of students' enrolment and progression towards the completion of a qualification. [1] Globally, there are a growing number of postgraduate students. [2] With the increased number of postgraduate enrolments, attrition from such programmes is estimated at 40-50% in most countries worldwide. [3] High postgraduate student attrition has a huge impact on national resources and robs the labour market of highly skilled personnel, resulting in loss of financial investments and knowledge. [1,4] Student persistence to completion in undergraduate and postgraduate studies is vital for academic institutions, society and the economy. [4] Higher-education institutions are awarded funds based on the number of undergraduates and postgraduates that they produce. [4] The impact of non-completion on undergraduate and postgraduate programmes results in decreased funding and affects resource allocation. [5] Furthermore, the effect of student persistence at the societal and economic level can be observed in the production of a highly skilled workforce that is able to generate advanced and creative ideas to improve the economy and society. [6] Student persistence to completion in postgraduate programmes is associated with factors related to students and academic institutions. [1,3] Student-related factors comprise age, time management, time from last degree, learning approaches and social connections, such as peer, family and employer. [7] Factors related to academic institutions include: mode of study, i.e. whether students are enrolled full-time or part-time, faculty support and academic integration. [1,7] In South Africa (SA), 10 universities offer Master of Public Health (MPH) programmes. MPH students come from diverse professional backgrounds and are primarily part-time students who reside off campus. [8] Most programmes are characterised by high attrition rates and prolonged time to completion. [9] The throughput for MPH programmes in SA ranged from 25% to 60% between 2009 and 2014. [9] The throughput for the University of KwaZulu-Natal, Durban, SA for the cohort of students who enrolled between 2009 and 2011 and graduated between 2012 and 2014 was 25%. Although a number of students leave MPH programmes prematurely, the context for these students may not differ from that of students who persist to completion. The aim of this study was to gain a deeper understanding of the phenomenon of persistence to completion in an MPH programme. Methods A constructivist approach was adopted to understand the phenomenon of student persistence to completion among MPH graduates. A case study design was implemented. Face-to-face in-depth interviews were conducted with MPH graduates from the University of KwaZulu-Natal. Purposive sampling was implemented by recruiting participants who were available at the time of data collection. Ten interviews were conducted until saturation was reached. Saturation refers to when no new information or themes are observed in the data. The in-depth interviews, fo...
