Introduction University-led higher education for paramedics has been in place for over 20 years, with students in these programs required to complete supervised clinical placements with an experienced paramedic mentor. This investigation aims to establish whether the non-rotation of paramedic students between paramedic mentors while on ambulance-based placements aids or hinders the undergraduate paramedic student’s development of competencies. Methods Purposive and convenience sampling methods were used, with semi-structured group interviews conducted with second year undergraduate paramedic students for data collection. Thematic analysis was used to draw meaning from the collected data. Results Five key themes emerged from within the data. Students reported difficulties in maintaining relationships with their assigned mentors, particularly in situations where conflicting schedules and role changes necessitated frequent rotation between mentorsStudents reported feeling there was great variety in the way competency-based learning is managed by paramedic mentors, leading to inconsistencies in assessment. Students also described comparing their own personality and clinical practice against mentors, in order to self-identify more appropriate mentors during the placements. Conclusion This research provides an initial insight into how paramedic students perceive the effects of non-rotational ambulance-based placements on the development of competencies. Based on the findings of this research it is not possible to draw firm conclusionas to whether the non-rotation of ambulance-based placements aids or hinders undergraduate student paramedics’ development of competencies. Further research is required in this area across a variety of settings in order to understand the applicability of these results.
