Teachers in the constitution in Indonesia are professionals who must meet pedagogical, social, personal, and professional competencies. This qualitative research with a phenomenological approach aims to explore the experiences of the teacher professional education program (PPG) participants in gaining soft skills. The research data were collected through in-depth interviews conducted on fifteen PPG participants consisting of seven females and eight males. The fifteen participants attended PPG in five universities spread out from universities in Central Java, West Java, Yogyakarta Special Region, and Jakarta Special Capital Region. The sampling technique used was purposive sampling. Data analysis was carried out through the horizontalization, texturally, structurally, and essential descriptions stages. The results of this research found that PPG participants received soft skills learning in hidden curriculum patterns so that each participant had an initial understanding and how to get various soft skill understandings. Soft skills obtained by participants during the PPG implementation are self-confidence, collaboration, hard work, respect for culture, patience, wisdom, maturity, mental resilience, humility, responsibility, creative thinking, positive thinking, cooperation, humility, respect for others, and tolerance. This research recommends that soft skills learning at PPG be implemented with a structured curriculum so that participants have better abilities as teachers.
