The article considers the process of self-identification as social progress. Theoretical researches of concepts of self-identification and identity are stated. The relationship of self-identification as a factor in the formation of personal identity is analyzed. The process of self-identification can be considered as a component of identification of a person with certain social groups, norms, values, traditions, religious dogmas, certain patterns of behavior and so on. Self-identification is a process of formation of personal identities, which includes the search for a certain identity as a model for personal development, identity formation or change its structure, the choice of certain values and qualities in the structure of the identity. Self-identification is a dynamic process of development of human self-consciousness, which is an important mechanism for the formation of personality. Through the concept of «identification» Freud defines the mechanisms of cognition and understanding of another person and social groups. Identification acts as a mechanism of personality development which consists in the unconscious identification of the subject with the object. Freud emphasizes that all types of identification are mechanisms of personality development. E. Erickson, characterizes the concept of self-identification through the concept of «identity». In turn, identity acts as an assimilated image of the individual in relation to the world around him. The concept of identity and self-identification is essentially plural, thanks to which it is actively applied to various aspects of modern reality. For a person whose originality and uniqueness are postulated from birth and by their own name and the right to show individual character traits, the concept of self-identification is extremely relevant. At the same time, the concept of «self-identification» is unstable and mobile, while acting as a leading and guiding self-concept of the person in the changing system of today. Self-identification is also an expression of the need to integrate certain values into the structure of personality, the desire to master certain knowledge and competencies. The process of self-identification includes identifying oneself with another person, social group, community of people, a certain pattern or image, defining oneself, one's social and moral guidelines, influencing one's own behavior and decisions. In this case, the individual must answer questions about their self-determination, place in life, their desires, goals and plans, opportunities, limitations, ideal image, and so on. The connection between self-identification and morality, on which the preservation of a certain identification status depends, should be taken into account here.
