The increasing popularity of outdoor learning (OL) amongst researchers and practitioners highlighted the need to further investigate primary teacher trainees (PTTs) perception towards it and how this may be related to their nature connection. Participants were PTTs who were considering attending Forest School (FS) Training Level 1 as part of their Initial Teacher Education (ITE) course. This mixed-methods research employed the Nature Relatedness (NR) scale to measure trainees' relationship with nature. Semi-structured interviews with those who chose to attend FS training were conducted to ascertain their perceptions and attitudes towards the training. Through Thematic Analysis of interviews five themes emerged, including favourable perceptions of FS Training and OL for their future teaching career and a positive nature connection. A significant difference in the mean NR scores was identified with higher NR scores for the group who chose to attend the FS training in comparison with those who did not.
