There is growing recognition of the importance of soft skills in improving young people’s labor market outcomes. However, rigorous measurement of specific soft skills in the context of a large-scale field study is often challenging, and hence there is little evidence on the levels of some such skills among vulnerable youth populations, as well as potential gender gaps in such skills. Moreover, there is little causal evidence as to which skills or sets of skills are most malleable in late adolescence and early adulthood, and which may have the highest labor-market returns for such populations. This study will deploy novel measures of key soft skills with a sample of young male and female adults in urban and peri-urban Tanzania. Building on recent advances in psychology and behavioral economics, as well as BRAC’s Empowerment and Livelihood for Adolescents (ELA) curriculum, we will create training modules focusing on two different sets of soft skills. We will use an individual-level randomized controlled trial to estimate the causal impacts of these trainings on young men and women's skills and on their labor market outcomes.

Experimental Design

Experimental Design
This study will consist of an individual-level randomized controlled trial among 4800 youth from 40 communities spread over three regions of Tanzania: Dodoma, Dar es Salam and Iringa. Our community sampling frame will consist of clusters which have: at least 120 eligible young men and 120 eligible young women within a one-mile radius; community leaders who confirm interest in the program; and an existing venue suitable for hosting a training. We will randomly select 40 communities from the list of communities meeting these criteria. Within selected communities, we will conduct a listing to create an individual sampling frame of all eligible young men and women, defined as being: primarily aged 18-24, with possible inclusion of 16-17-year-olds and 25-26-year-olds if needed to attain the desired sample size; not in full time education or attending boarding school, and not in full time formal salaried employment. From this sampling frame, we will use a computer to draw a random sample of 60 adolescent girls and 60 adolescent boys per community, and to randomly allocate them to one of three treatment arms – receiving training on the first set of skills, receiving training on the second set of skills, receiving training on both sets of skills – or the control arm (no training).
