It is with enthusiasm and anticipation that we celebrate the launch of this international scientific journal (Issue 1) that focuses on research examining the complex topic of skill and competency development. GJSD serves the scientific and academic community, as well as educators, teachers, trainers, professionals in the industry, decision-makers, and broader society in general. In line with the mission of the publisher, the GiLE Foundation, we are dedicated to “support young people’s pursuit of a successful and meaningful life by developing their competencies and through research and advocacy”.
