Learning in teams is aimed to develop skills of solving problem-based tasks by using various competences, performing effective virtual communication and knowledge exchange activities. The problem analysed in this article deals with the individual performance measurement for students working in virtual teams. The evaluation and management of learning processes in virtual teams has many specific features, as compared to the face-to-face learning mode. The goal of the article is to present evaluation framework, which could allow us to estimate performance indicators, not only by measuring efforts of teams or individuals by finding specific variables of virtual communication., but also by revealing their causal relationships to the final outcome of the virtual project work. Therefore the suggested method is based on the balanced scorecard concept, applied for virtual teamwork evaluation along analysed dimensions of the teamwork. The balanced values are included to the compound grade for individual performance evaluation, which is designed by calculating the teamwork grade and multiplying it to individual performance coefficient. These evaluation compounds consist of grades, estimated of individual and team input variables, and the results of internal self-assessment of the virtual team members. The experimental data of the real virtual teamwork was applied for analysis of the quality of suggested method, aimed to ensure that the final grade of the project assessment reveals the individual progress of each learner related to team performance.
