Technology Education hours offer to the mentally disabled pupils the opportunity to acquire a system of knowledge, capabilities and attitudes that streamline future integration into social and professional life. Having and using the approaches of the learning activity at the pupils with mental disabilities, and also the notions of "working culture" and "psycho-pedagogical conditions", we have identified the argument that would justify the didactics of Technology Education in the auxiliary school, centered on the formation of the practical skills at the pupils in primary school , useful for both personal and socio-professional development, based on a variety of psycho-pedagogical conditions reflecting the efficiency of the working culture. Formation of the working culture at the pupils with mental disabilities can be efficiently achieved if certain psycho-pedagogical conditions are respected. These, applied in the teaching-learning process of the Technology Education, facilitate the obtaining of the goals and of the final results determined by the component of the learning – working culture.
