Communication-significant and communication- insignificant mistakes in writing of Russian as a foreign language

Abstract. The problem of mistakes evaluation in the test-takers writing of Russian as a foreign language has been examined in this paper. Experts have difficulties with the introduction of a new criterion of mistakes analysis (criterion of success / failure of a communication act). The author concludes that the communication failure is often a result of incorrect syntactic constructions, whereas the morphologic and lexical deviations seldom influence the efficiency of communication.
