The article discusses the grammatical competence in the English language of future teachers in the undergraduate program as a component of effective foreign language teaching in the form of ability to correctly apply the morphological, syntactic and lexical norms of the English language in solving practical problems. Taking into account the teaching of English as a pedagogical specialty, it is necessary to take into account the communicative and pedagogical components of professional competence. Based on theoretical provisions in the form of an analysis of pedagogical conditions of the organization of education, the current study views the specifics of improving morphological grammatical skills in the form of teaching tense forms of English verbs on the material of authentic texts from classical literature.

Increasing the level of foreign language communicative competence will contribute to the improvement of theoretical and linguistic knowledge, to the formation of practical skills in the form of teaching the norms of the literary language.
