We have shown that personal and professional development is a complex multifaceted process, which aims at the formation of future teachers not only general and professional competences, but also envisages the development of their personal meanings. The study identified the main components of personal and professional development of future educators, namely: personal (value-personal and professional settings; self-knowledge and self-development; professional elevation); 21st century skills (critical thinking and problem-solving skills; communication and collaboration skills; digital skills), research and development (ability to highlight the research problem; work in a team; design stages of the research; select the necessary tools to solve the research task; analyze, organize, summarize the information received; to acquire new knowledge for their own use in their professional activity; to create and present their own educational products), reflective (self-concept, personal qualities and results of their own activity; self-analysis, self-knowledge, self-diagnostics, self-assessment, self-development, self-improvement; ability to detect mistakes, disadvantages of their own professional activity, and correct them).
