For more than 10 years, the COHDA study institute has been working along the entire value chain of these different issues, on behalf of numerous stakeholders at both national and local level (DRIEETS, France Compétences, OPCO, job centres, universities, regional councils etc.) and for various areas of activity (construction, commerce, energy and environment, events, health and more). Budgetary constraints and an increase in the number of people to be taken care of have prompted public employment and integration policy stakeholders to ensure that their interventions are effective and optimised. Our support therefore takes various forms (future/integration study, study of recipient experience/path, survey of recruitment needs etc.) to monitor the results of training activities, identify levers to enhance the attractiveness of economic sectors with skills shortages, experiment with innovative training formats to boost professional integration, and more broadly highlight investments to be made to promote employment and employability.
