In order to improve the quality of education, the implementation of the priority national project “Education” I consider it appropriate:
to review, in the light of modern requirements, the current (in some cases obsolete) state educational standards and educational programs;
significantly increase the demands on the quality of textbooks and teaching aids, strengthen their scientific basis and focus on a high level of professional training of specialists;
to develop, in the light of modern requirements for the preparation of competitive graduates, model regulations on educational institutions of the corresponding types and types, charters of educational institutions, collective agreements;
to immediately finish the five-year work on the development of the draft Code of the Russian Federation on education and submit it to the State Duma, pay special attention to it: the independence of educational institutions and students (their rights, duties and responsibilities); the role of public organizations in improving the quality of education and increasing the effectiveness of educational institutions; the development of integration of educational institutions of all types and types; recognition abroad of Russian educational documents (diplomas, etc.) abroad; free equal participation of educational institutions and citizens of the Russian Federation in the global market for educational services.
