There are many examples of crises and catastrophes in the history of mankind. Almost the entire spectrum of natural disasters is possible in Kazakhstan. In particular, earthquakes, floods, fires in forests and steppes, snowstorms, and others. In all mountain and foothill zones, there is a danger of landslides, the threat of snow drift. In addition, there are situations that have arisen for man-made reasons. These catastrophes are the result of human activity. Such extreme situations require the concentration of all physical and psychological capabilities of a person. This is especially important for military personnel who often operate in extreme or critical conditions. Psychological readiness to solve such situations gives the individual confidence in the correctness of their own actions and, in the end, leads to a successful result. The purpose of this article is to present the results of research in the framework of a master's thesis. The main focus is on the analysis of the features of psychological training of military personnel to act in an extreme situation. The studied problem is revealed by the authors from the point of view of modern approaches to the psychological training of military personnel in a critical situation. The research methods used (analysis, generalization, experiment) allowed us to reveal the depth of the problem relevant to military psychology. The research is based on the results of modern research by Kazakh and foreign scientists. Approaches to the interpretation of the essence of the content of the concept "extreme situation" are considered, and the factors that determine the specifics of psychological training of military personnel to act in a crisis are highlighted. The concept of "psychological readiness of military personnel to work in critical (extreme) situations" is defined. Statistical results of the experiment are presented. The experimental activity carried out in the course of experimental work has a high practical significance, since it was successfully tested through the implementation of the work of the military unit 3176 "K" in Pavlodar and can be used in the psychological training of military personnel. The article is devoted to the actual problem of psychology. The results presented in the article may be useful for military psychologists.

Main problem: The article highlights the problem of tests as methods of psychology, the influence of validity and reliability on the results of psychological research. Purpose: Uncovering the significance of validity and reliability on psychological research results. Results and their significance: Testing is an important method in psychology, allowing measuring various aspects of the psyche and behavior of a person. The history of the development of tests in psychology goes back more than a century and began with the work of Francis Galton and Alfred Binet. Over time, the tests have become widely used in various fields such as education, personnel selection, clinical diagnosis and research. Basic requirements for tests include reliability (repeatability of results), validity (measurement accuracy), standardization (same test conditions) and objectivity (lack of subjectivity in assessment). Tests must be designed using psychometric principles to ensure accuracy and validity of results. Modern tests include a variety of measurement techniques, such as tests of personality, intelligence, aptitude, and professional skills. The use of tests in psychology requires professional training to correctly interpret the results and make valid conclusions. Testing as a method of psychology continues to evolve, and its role remains key in the study of the human psyche and behavior. Testing in psychology has a wide range of applications, including assessing personality traits, identifying psychological disorders, and predicting behavior and success in various areas of life. The development of computer-based tests and online platforms makes testing more efficient and convenient for researchers and participants. Modern tests increasingly take into account cultural differences and the diversity of individual characteristics, which contributes to more accurate and tailored assessments. It is important to remember that the use of tests requires ethics, confidentiality and compliance to ensure the reliability and validity of the data obtained.
