The article focuses on the assessment of mediation competence in the context of the Content and Language
Integrated Learning (CLIL). We offer new assessment scales developed with the use of descriptors for mediation
from the CEFR Companion Volume (2018). The approach to assessment of oral performance that we discuss
combines global and analytical marks. For the majority of classroom teachers in Russia, this issue has become very
important from two points of view: a) how to introduce new scales of mediation and connect them adequately
with traditional speaking skills, described in the literature (Pavlovskaya 2017), and b) how to harmonize global
assessment with analytical scales. The research is based on the experience of evaluating the mediation skills of
students of the Graduate School of Management, St. Petersburg State University. The implications of the method
for classroom teaching are discussed.
