This study used a descriptive correlational design, four tools were used to collect the data; Nursing coaching leadership scale, self-monitoring scale, nurses' reporting errors scale and ethical awareness scale. Results:  revealed that the majority of studied nurses had a high perception level of nursing coaching leadership, and intention of errors reporting (81.0%, &77.0% respectively), while more than two thirds of studied nurses had a moderate level of ethical awareness, and self- monitoring (72.0%, & 68.5% respectively).  Conclusion: This study confirmed the positive correlation between nursing coaching leadership, self-monitoring, intention to report errors, and ethical awareness.
