The assessment of the public civil servants’ activities should provide the personnel management decision-making process with the necessary information on the issue of efficiency and effectiveness. The authors conducted a review of domestic and foreign practice of evaluating professional activity in the civil service and concluded that the research problems of the methodological aspect of this topic are relevant. The approaches used by the authorities are not focused on individualising the contribution of a civil servant to the fulfillment of the objectives of the structure in which they hold the position. The authors propose a system for evaluating the effectiveness and efficiency of performance, which includes three aspects. The operational unit measures the current activity according to the indicators of the official regulations using a quantitative scale. The perspective block evaluates the professional and personal development of civil servants. The block for assessing the level of workload according to the responsibility matrix records the participation of a particular employee in achieving collective performance results. The experience of the territorial division of the federal executive authority (Krasnoyarsk State Statistics Service) is described as one of the options for the assessment approach. The article presents the results of a survey of Krasnoyarsk State Statistics Service employees on the implemented tool for identifying the achievements within the perspective block. It is concluded that the possibilities of personnel decisions are expanding in the areas of developing individual trajectories of professional and personal growth of employees, ensuring a balanced workload and building a fair personalised motivation system.
