The sectoral analyses, studies of firms’ practices and observations of work carried out by Céreq are based on analyses of the  Générations surveys (a national programme that tracks the early years of the working lives of young people of all levels of education and training) and the  Defis surveys (on continuing training for employees), as well as on ad hoc surveys, field observations and the use of statistical data. These studies focus on analysing work and understanding the changes in occupations and the organising principles of sectors and industries, as well as on firms’ practices and identification of their skill requirements. The analyses, which connect directly with the major (digital and ecological) transformations, also adopt approaches looking forward over the medium and even long term.
