Problem and goal. The practical (pedagogical) training sites based on Moscow schools in the context of effective development of the resources of the Moscow Electronic School by future computer science teachers are analyzed. The goal is to identify the correlation of the digital footprint obtained as a result of the development of the school network activity index based on data on the actions of teachers and students in e-learning environments and of educational organizations identification corresponding to this index, as well as the methodological activity of schools in Moscow - the bases of practical (pedagogical) training of future computer science teachers. Methodology. The analysis of regulatory documents and the database of Moscow schools, where the Moscow City University students of the Computer Science direction are engaged in practical (pedagogical) training, reflection on the content of the knowledge obtained, search for criteria for selecting basic schools for conducting practical (pedagogical) training of future computer science teachers, local pedagogical experiment were used. Results. It was found out that the activity of schools in the development and use of educational resources of the Moscow Electronic School is not a prerequisite for cooperation with these schools. At the same time, the knowledge of information technologies, including the technology of working with the resources of the Moscow Electronic School, by future subject teachers, is an integral part of the professional competence of a modern teacher, and especially a computer science teacher. Conclusion. The basic criteria for selecting sites for industrial practices of future computer science teachers, in particular students of the Moscow City University, are proposed. The formulated criteria for selecting basic schools for conducting practical (pedagogical) training of university students will allow them to successfully solve the tasks set for this type of educational activity, achieve their goals and form professional and pedagogical competencies.
