The development of strategic planning in Russia using program-targeted budgeting approaches, the adoption of effective managerial decisions in the public sector determines the relevance of the problem of improving the efficiency of projects and programs implemented mainly at the expense of the state budget. The importance of these issues is growing due to the scale of the tasks solved through government programs and national projects, significant amounts of resources allocated for their implementation in the presence of budgetary constraints in the context of global instability and a significant level of uncertainty. An analysis of the domestic regulatory legal, methodological framework governing the development of national projects, international experience in project management, shows that the assessment of the quality of project development is not sufficiently carried out and methodologically supported. At the same time, the success and efficiency of the project is largely determined by the quality of the development plan for its implementation. The article defines general principles and proposes a model for assessing the quality of the development of national and federal projects. Based on the approbation of the proposed tools, shortcomings in the planning of national and federal projects were identified, proposals were made to improve the methodological support for the development of plans for their implementation. It is concluded that the implementation of project quality assessment procedures will improve the planning of state projects, including through increased performance discipline, a more balanced and thoughtful approach of developers to drafting projects. The combination of a formalized state assessment and independent public expertise will ensure a high degree of objectivity in the audit of project plans and will help improve the efficiency and effectiveness of their implementation.
