Inadequacies in Tanzania’s education and training systems compromise the quality of workforce skills, giving rise to skill shortages, and constraining the operations and growth of formal sector firms in the country. This study addressed these concerns using data from a unique Enterprise Skills Survey that asked Tanzanian employers about the education, training, and occupational mix of their workforce, the skill gaps in cognitive, noncognitive, and job-specific competencies affecting their operations, and the strategies they are using to overcome these skill gaps. The study investigates the consequences for firm productivity of employers’ choices about their optimal skills mix, and their strategies to mitigate shortfalls in skills supply.
