1 TERMINOLOGICAL BASIS OF THE DUAL SYSTEM OF EDUCATION AND TRAINING In the first chapter of our scientific monograph, we will summarize the necessary terminological bases of the processed topic, based on the most current definitions and from the latest sources. Lifelong learning is a term that covers lifelong education and lifelong upbringing. Lifelong education is general education, vocational education and training, non-formal and informal learning throughout life, which leads to the improvement of knowledge, skills and competences from a personal, civil, social and professional point of view. This includes the provision of professional guidance and counselling services. Lifelong upbringing can be defined, in accordance with other authors, as a lifelong process, focusing mainly on the affective aspect of personality, which is intended to prepare a person for social life and pass on the experience of the older generation. So, the lifelong upbringing is a process of deliberate action on a person’s personality with the aim of deliberately and purposefully shaping and influencing the conditions that will enable each individual to develop optimally in accordance with individual dispositions, stimulating his or her own desire to become an authentic, internally integrated and also become a socialized personality. So, lifelong upbringing is a process associated with the development of each individual (ontogenetic aspect) and with the development of the whole society (phylogenetic aspect). By education, we perceive upbringing and education as a whole, whit what we are pointing to the real complexity of upbringing and education. (Barnová et al., 2019). According to Kováč (2015), vocational education and practice are part of the educational process in which knowledge, skills, and competencies necessary for the pursuit of a profession, group of occupations or professional activities are acquired. It is divided into theoretical lessons and practical training. In our monograph we will perceive the dual system of education and training and preparation system based on: a. Contractual relationship between the employer and the student (learning contract); b. Contractual relationship between the employer and the secondary vocational school (dual education contract); c. effective practical education directly at the employer at the practical training workplace;
