 From traditional to contemporary practice of psychoeducation 
On the occasion of the 50th anniversary of the creation of psychoeducation as a university discipline, the developmental trajectory of psychoeducational intervention is traced on the basis of the events related to the evolution of its purpose (reeducation, readaptation and adaptation) and their repercussions on the diversification of its professional fields of activity. The transition from traditional practice (vocational call and power of action) to contemporary practice (professional discipline and power of knowledge) is characterized in terms of the evolution and the preponderance of clinical accompaniment, the exercise of an advisory role and the psychoeducational assessment. Research data and testimonials will support the statements made and the nature of the challenges psychoeducators face in their area of work. Given the variations in the conditions under which psychoeducation is practiced, the conclusion raises questions about the future of psychoeducational intervention.
