The purpose of this thesis was to explore the development of elite sport through national sport policy within a developing country, Jamaica. Taking a qualitative approach, the thesis drew on the SPLISS framework (De Bosscher et al., 2006, 2015) to understand government influence in the development of elite sport, through policy, and to investigate other contributing factors for elite sporting success. A logic model illustrated the input-throughput-output pillars of the SPLISS framework, and aided in the interpretation of both a theoretical and rival proposition (Yin, 2018). This thesis purpose, accomplished in part by exploring the most successful elite sport in Jamaica, athletics (track and field), incorporated three interconnected studies on that developing country’s national sport system, a sport system that produced its first Olympic success in 1948, forty-six years before the introduction of national sport policy. Three interconnected studies allowed for findings that highlighted the roots of Jamaica’s sport development, beginning with the introduction of a school and community sport system by the former colonial British government, and retained and expanded by the Jamaican government from 1962. The findings also highlighted that the school and community sport systems facilitated a local approach to the development and training for athletics. It included factors outside of the influence of government, such as the impact of coaches and role models that assisted in creating a fraternity in the sport through tradition, culture and passion, and established an environment for elite sport. This environment involved a collaboration between educational institutions and the professional local club system, and represents the critical elements in the success of athletics, indicating that the influence of government policies for sport development was not impacting international sporting success up to 2017. The interconnected studies also provided support for gaps identified in the SPLISS framework and the literature on elite sport policy. For SPLISS, the findings provided evidence in understanding what happens when input factors are processed (the ‘black box’) leading to outputs, and national outcomes. For the literature, the thesis found that an historical context is important in understanding the coalescing of micro-, macro-, and meso-level factors for elite sporting success.
