As a career develops throughout a person’s life, the andragogue consultant involved in this process, providing career guidance for adults, counselling, information and career development services, is particularly relevant. The article analyses, both theoretically and empirically, what characterises the process of providing career guidance services to adults, and how the andragogue consultant’s activities are manifested in providing support, guidance and counselling to those pursuing their lives and careers. Thus, the theoretical discourse of career guidance service andragogue consultant activity is analysed, and empirically substantiated career guidance service features, and links with andragogue consultant activities, are provided. The qualitative research carried out reveals that the characteristics of career guidance services are revealed through the activities of the andragogue as a competent career and life consultant. The summarised theoretical, documentary and empirical analysis suggests that the andragogue consultant’s career guidance, client-centred, needs-based approach is designed to help an adult choose their education and employment, career planning and management competencies, and create and develop a career.
