insufficient vocabulary is one of the main sources of school poor progress of first-graders-foreigners. The identification of knowledge and use of words is facilitated by language diagnostics of children entering the first grade of Russian state schools of compulsory education. The purpose of this study is to determine the volume of foreigner vocabulary and identify gaps in knowledge by diagnosing lexical units in student speech. To achieve this goal, the analysis of scientific and methodological literature, diagnostic testing, quantitative analysis and descriptive methods were used. Diagnostics of vocabulary volume of first-graders-foreigners was carried out on specially selected lexical units necessary for communication and assimilation of the school curriculum. A picture dictionary (manuscript) was developed in which the visual material is systematized and grouped according to the thematic principle and includes the most commonly used Russian vocabulary in the first grade. It is a scientific novelty in the organization of the process of language diagnostics of first-graders-foreigners. The picture dictionary can be used as diagnostic material for input and final testing when determining the level of Russian language proficiency of first-graders-foreigners with poor language skills and in remedial group and individual work. In the course of the study, problem areas were identified on the main lexical topics, which are important both in terms of communication and in the learning process and the criteria for assessing the volume of the vocabulary were described. The results of the study of the volume of vocabulary can be used in scientific work in the field of methods of teaching Russian as a non-native language, as well as in the work of a teacher when planning educational material with first-graders-foreigners.
