Clinical simulation is a teaching strategy to assist nursing students to connect classroom knowledge to the clinical setting. Teaching clinical simulation requires special training, but many nursing faculty who teach clinical simulation do not receive clinical simulation training. The purpose of this study was to determine if the effects of formal versus informal simulation training impacted nursing faculty's self-ratings of their competency in facilitating simulation and identify areas for needed educational support. A quantitative descriptive approach was used and grounded in the National League for Nursing and Jefferies (NLN/JSF) theoretical framework. This framework focuses on the relationship between teacher, student, and educational experience. Data on 102 faculty members from prelicensure nursing programs in Maryland completed the Debriefing Assessment for Simulation in Healthcare (DASH-SV) survey. Data analysis using the independent-samples t-test revealed no significant difference in nursing faculty's perceptions regarding how they facilitate clinical simulation between nursing faculty who are formally trained to teach clinical simulation and those who are not. However, there was a significant difference in one element of the DASH-IV which measured the skill of helping students achieve or sustain good performance. The data will contribute to the nursing simulation literature by providing a better understanding of what faculty members perceive as their strengths and weaknesses in teaching clinical simulation. The findings of this study can influence positive social change in nursing by providing nursing administrators with information about faculty perceptions of clinical simulation and influence decisions on training of nursing faculty in using clinical simulation.
