Linking Instructional Resources, Work-integrated learning and Employability Skills acquisition: A Meta-Analysis of Competence-Based Education for Livestock Training in Tanzania
This meta-analytic review examines the influence of instructional resources and Work-Integrated Learning (WIL) on employability skills acquisition within the Competence-Based Education and Training (CBET) framework in Tanzania’s Livestock Training Institutions (LTIs). The study systematically synthesised evidence from published research, institutional tracer studies, and policy documents spanning 2005–2025, guided by the PRISMA approach. Data were drawn from 42 empirical studies and reports, and analysed using a mixed-method meta-analytic technique combining quantitative aggregation and qualitative thematic synthesis. Findings reveal that adequate instructional resources, including functional laboratories, livestock units, and ICT- supported learning, have a strong positive correlation (r = 0.68 – 0.81) with students’ technical competence, job readiness, and employability skills. Institutions equipped with modern learning environments produced graduates with 20–35% higher employment rates than those from under-resourced settings. Moreover, structured workplace learning experiences including attachments, internships, practicums, apprenticeships, co-op programs, and fieldwork enhanced graduate adaptability and confidence by 25–45%, thereby confirming the pivotal role of experiential learning in strengthening CBET effectiveness. However, inconsistent implementation, limited trainer delivery capacity, and uneven policy enforcement undermine the system’s full potential. The study recommends adopting a Livestock Education Employability Model (LEEM) that emphasises resource upgrading, structured Work-Integrated Learning, digital innovation, and policy alignment. Building on this model, strengthening CBET through sustained investment, digital transformation, and designed industry partnerships is essential to aligning curricula with labour market demands and, in turn, advancing national goals for livestock sector transformation, employability skills development, and youth employment.
