As technical and vocational education and training (TVET) continue to occupy a prominent position in Africa's development, addressing the growing concerns about young women's under-participation in science, technology, engineering, and mathematics (STEM)-related TVET has become urgent. This paper draws on the critical capability approach of vocational education and training (CCA-VET) to critique the TVET policy discourse on the participation of girls and women in STEM-related TVET. The paper employed the practical argumentation approach, a critical discourse analysis approach to achieve the paper's aims. The paper's central thesis is that for education policies to transform young women's under-participation in STEM-related TVET, it is urgent to move beyond human rights-based, and human capital approaches to adopt a comprehensive theoretical approach, such as the critical capabilities approach. The paper concludes that breaking this hegemony of human rights and human capital approaches to TVET policy can be achieved by re-conceptualising TVET policy discourses. The re-conceptualisation of TVET policy discourses can be achieved by admitting the critiques of these dominant theories that underpin most TVET policies and then adopting the CCA-VET as a better alternative approach to framing TVET policies.
