Young people are the most important strategic resource for development of any society, therefore, the growth of the knowledge-based economy and development of the country in the macro perspective depend on the way its educational and professional potential is formed and fulfilled. Mastering new knowledge and developing the intellectual abilities of young people lead to the development of the educational potential of the nation—the most important qualitative characteristic of the workforce and the population. A significant increase in the level of educational potential of young people can be only implemented with the use of modern communication technologies and creation of hybrid educational environments. The paper considers the issues of developing a technology for creating a hybrid educational environment, including, along with existing research laboratories, various virtual laboratories with the possibility of full immersion of school students in their space, which would contribute to increasing the level of vocational guidance for school children, namely: improving their knowledge of professions, interest in engineering areas, confidence in choosing a future career, development of professionally significant competencies; and would also be very attractive to them. The authors of the work focus on the virtual component of the hybrid educational environment of the university's engineering school. The formal description of the technology uses functional diagrams in the IDEF0 notation. The following basic programming environments are used as development tools: Twinmotion, Bigscreen, 3DVista Tour, LMS Moodle. A hybrid educational environment of the university was created, including: adapted resources of existing scientific and educational laboratories for the tasks of the engineering school, developed virtual images, created digital twins of technological complexes for conducting computational experiments, developed educational virtual laboratories that allow organizing the educational process under the control of the LMS Moodle system during early career guidance. Hybrid educational environment of the university can be considered as a predecessor of the model of supervised and unsupervised e-learning for young people.
