Education plays a vital role in a person's life as it provides them with the necessary knowledge, skills and tools needed for the working world later on. With the introduction of the Millennium and Sustainable Development Goals in the 21st century by the international community, more children, especially in Africa, are attending school. With fast-growing economies, such as Kenya and Ghana, and the Sustainable Development Goals' particular focus on secondary education, the relationship between secondary education and economic development becomes fascinating. While most studies on this topic have looked at primary education's association with economic growth, this literature review tries to fill the gap in the academic literature by documenting and analysing the relationship between secondary education and economic growth in Sub-Saharan Africa. A general overview of the field and three detailed case studies are given. In addition, human capital theory is used to explain how people acquire knowledge and use it to their benefit to contribute and be productive in an economy. For this literature review, six major academic research databases have been searched for quantitative studies examining the relationship between education and economic growth in Sub-Saharan Africa. Most studies found a positive association between secondary education, largely proxied through enrolment rates, and national economic growth. This shows that investments in secondary education can boost local economies and provide people with more opportunities. However, more research must be conducted as the quality of education has been neglected in studies examining the relationship between secondary education and economic growth in Sub-Saharan Africa.
