A quasi-experimental research design with a two-group pretest-posttest aimed to examine the effects of simulation-based learning on knowledge and skills in emergency patient triage among nursing students. The sample consisted of 43 third-year nursing students, selected based on specified criteria through simple random sampling. The research instruments included: 1) a high-fidelity simulation scenario for assessing and teaching emergency patient triage skills, which was developed by the researcher, content-validated, and revised based on expert feedback before implementation. 2) A high-fidelity simulator 3) The data collection tools included a general information questionnaire for the participants, a knowledge assessment questionnaire for emergency patient triage, and a skills assessment form for emergency patient triage. The knowledge assessment had a content validity of 1 and an internal consistency (Cronbach’s alpha) of .70. The triage skills assessment had a content validity of .98 and an internal consistency of .89, respectively. Data were analyzed using Wilcoxon matched pairs sign-rank test and Mann-Whitney U test statistic.The research findings indicated that after the implementation of a high-fidelity simulation for emergency patient triage, there was no statistically significant difference in post-simulation knowledge scores between the control and experimental groups (p > .05). However, the experimental group showed a statistically significant increase in knowledge scores after the simulation compared to their pre-simulation scores (p < .05). Additionally, the experimental group demonstrated significantly higher emergency triage skills than the control group (p < .01). These findings support the integration of high-fidelity simulation with conventional teaching methods to enhance nursing students’ education
