Relevance. The transformation and development of modern information technologies (IT) have affected the educational process of all educational institutions, which makes it necessary to justify the application of numerous pedagogical innovations using IT in the vocational training of future teachers. This makes developing important for future educators to understand the SMART-complex as a component of the information education environment, since in order to develop the SMART-complex, the teacher must understand its` structure and the interaction of all components. Purpose: to highlight and characterize the main elements of the SMART-complex as an educational information environment of an educational institution, to prove the advisability of their use in the training of future teachers. Methods: direct analysis and synthesis are for substantiating the relevance of the problem, that is under consideration; deduction is for identifying the main structural elements of the SMART-complex, modelling is for the image of the structural appearance of the SMART-complex, generalization is for taking the stock of the work. Results: the emergence of the concept of the SMART-complex and some elements of its structural type were analysed; the existing SMART-complex models were described and generalized and their main structural elements were defined; the need to introduce SMART-complex as a component of the information education environment was noted. Conclusions: SMART-complex is an information dynamic system of educational and methodological direction with defined SMART-criteria (specific, measurable, attainable, relevant, time-bound), with static, dynamic and environmental components; SMART-cloud resource is a system for personalized delivery and processing of electronic content; services (e.g., cloud-based electronic storage) for handling documents, spread sheets, electronic presentations; video-web conferencing for creation of electronic questionnaires, tests; application of this resource allows to organise both general and individual work with the content, in fact SMART-cloud resource is a «core» of SMART-complex; available SMART-complexes correspond to the modern educational needs in the context of fulfilling the tasks of the New Ukrainian School and can be used in the training of future teachers.

Transformational changes both in the world on the whole and in the education system in particular are constanly creating new challenges for the professional qualities of teachers. There is a profound discrepancy between the needs of the modern student and the abilities to meet these needs on the part of the teacher. There are a number of reasons for this, namely, the difference between generations, teachers' low motivation for self-development, and low digital literacy. It is very important to take into account all of these issues while training future teachers. We have experimentally determined the relevance of using SMART complexes in the process of professional training of bachelors studying in the program "Secondary education: labor training and technology", Additionally, we have proved the need for active implementation of SMART complexes into educational and professional activities of teachers.
