The purpose of this research is to activate the potential of the future expert in physical culture and sports, to use it and to investigate the ways of self-development. The research was completed using the phenomenological design. The research was conducted with 50 physical education and sports teacher candidates attending the 1st and 4th grades in the 2021-2022 academic year. During the data collection process, a Semi-Structured Interview Form developed by the researchers and prepared by taking the opinions of three different field experts was applied. The answers were sought from the physical education and sports teacher candidates about their views on self-development, their views on the factors that hinder their self-development, their views on the institutions/organisations they benefited from while developing themselves and the development of their acmeological potential. Grouping method was used for data analysis and individual results were collected in different group environments. According to the results of the research, the situations that prevent the students from developing themselves and the data on the development of the acmeological potential were determined. It is thought that a similar study will contribute to the field.
