The IDB supports the development of knowledge, interventions, programs, and policies to improve the competencies and skills acquired by adolescents in the education system so they will contribute to a student's successful transition between school and work. The projects for this field include supporting the government of Costa Rica to improve the English as a foreign language project in order to close the skills gap between the demand in the labor market and the supply of the education systems in the field. As part of its research agenda, the IDB conducted a survey of young students from Chile analyzing their educational labor trajectory while measuring certain cognitive and non-cognitive skills, relating them to the education and labor performance of adolescents. The IDB also implemented The Employers’ Survey of Mandatory Skills (ENEHD, Spanish Acronym), that investigated the twenty-first century skills demanded by entrepreneurs for people under 25.
