Academic, religious, pedagogical, apostolic and personal formation experien-ces received there were analyzed in this case study –from a qualitative approach– by means of semi-structured interviews and focus groups. Personal and apostolic formations stand out among the results due to the characteristics of Istmina as a proper place for sensibilization and subjugation in proof of vocation. However, the reach of integral formation is questioned because academic formation presented meaningful deficiencies. In conclusion, even though formation experiences in vulnerable con-texts are appreciated –and contextualiza-tion of learning is deemed meaningful–, participants agree in the necessity of deve-loping strong competences to face educa-tional and apostolic practices.esArticle
