In this exploratory, descriptive survey of 295 nursing preceptors it was found that 98.3 per cent had evaluated nursing students. They cited numerous reasons as to why they should be involved in the evaluation process. Only 28.8 per cent had been taught to evaluate and 5.4 per cent had failed students. There is a discrepancy between how little preceptors are prepared for the evaluation role and how frequently they are expected to do so. Consequently, there is an onus on nurse educators to prepare clear evaluation forms, to assess students for suitability for preceptorship experiences, and to recognize evaluation as part of the preceptor's professional relationship with the student.
