The work of a professional mentoring, assessment and integration consultant for a psychological and educational companion program aimed at reducing dropouts from vocational training institutions in Algeria is based on assessing the subject's psychological and teaching activities, his personal resources and environmental conditions where he is, and helping him develop positive adaptability, with the aim of making the right personal and professional choices on his career path.This question prompted us to envisage a work plan of companionship and mentoring for the benefit of the guidance counselor, to accompany and mentor the trainees during the training and to prepare them for integration into professional life.
