Main internal HR risks as determined by JSC 'Russian Railways' are risks connected with the training level of its staff. Technical learning is a tool to sustain a high knowledge level of the employees and to assess their knowledge level. Presently, the emphasis is on modern information technologies, namely the e-learning system. Using these systems broadens opportunities to analyze employees learning results and allows real-time recording of potential deficiencies in the training level. However, due to a large number of personnel undergoing trainings, there is a necessity to develop methods for automated evaluation of the obtained results that will assist in managerial decisions. This work suggests a clusterization of the technical study outcome for automatization and also provides the necessary metrics for solving the problem.
