This investigation focuses on students' self-reported changes in personal, social and technical skills that took place during a six-week long expedition to East Greenland. A 105-item pre-and post-expedition questionnaire was completed by 60 young expeditioners aged 16 to 20. Before the expedition participants generally felt that they had high levels of skills and were well prepared for the expedition. Of the 49 items in the 105-item questionnaire which related to participants' personal, social and technical skills, 22 showed statistically significant differences from those expected by chance when tested using the chi-square test. In terms of their personal skills, participants self-reported statistically significant changes (p less than 0.05) in their ability to avoid depression, avoid loneliness, set priorities, achieve goals, solve problems efficiently, cope with constant cold, enjoy isolation, manage time efficiently, maintain physical fitness, be enthusiastic, demonstrate confidence and set goals. In terms of social skills participants self-reported statistically significant changes (p less than 0.05) in their ability to control their emotions, motivate others, organise others, live in crowded circumstances, lead through consultation with others and maintain personal hygiene. In terms of technical skills participants self-reported statistically significant changes (p = 0.05 or smaller) in their ability to prepare dehydrated food, tie on and use ropes in glacier travel, use crampons and take charge of rescuing a member of their party from a crevasse. These items indicate that participants learned about survival and general skills associated with expeditions as a result of experiencing the expedition.This analysis of self-reported changes in items relating to expedition participants' personal, social and technical skills shows that participants have rated themselves more highly at the end of the expedition in a range of useful social/leadership skills and personality traits. The question of whether these same skills and traits could be transferable to higher education, employment and life in future is raised as a futher area for research. The improved technical skills reported will be useful if the participants undertake further expeditions to similar wilderness areas in future, perhaps as leaders. The potential of the findings of this study for training future leaders on expeditions is considered. Findings from this study may also be worthy of consideration by companies and organisations involved in personal development and training programmes. (Contains 1 table.)
