The article presents the study of the performance efficiency of university teachers in the context of generational balance. The views of scientists on the problem of the generational theory in the field of higher education and science are presented. The use of tools for measuring teachers’ performance on the example of international scientometric databases and local systems for automated determination of performance results is presented, the prospects of its scalability in higher education institutions is proved. The dependence of the rating indicators of teachers` performance on the age of scientific and pedagogical workers is experimentally studied. The generational balance of teachers of higher education institutions is studied on the basis of the analysis of the ratio of age and publication activity of the most productive TOP teachers of universities occupying different positions of the consolidated ranking. A SWOT analysis of the generational balance of teachers of higher education institutions was conducted. The tendency of decrease of the percentage of young scientists among university teachers is revealed, the possible consequences are analyzed. The mechanisms of application of tools for measuring the university teachers` performance depending on the age category are described. The imbalance of different age groups of teachers indicates high risks of a generational conflict and may lead to a reduction of performance efficiency in the future. Performance measurement tools are an important factor for the implementation of educational management of higher education institution.
