Background: Midwifery students, clinicians and educators in Australia identified the need for improved feedback for midwifery students whilst they are on clinical placement; in particular formative assessment. The miniCEX or mini-clinical evaluation exercise is one approach to assessment that has been proven valid and reliable in medical education. The aim of this research was to develop, implement and evaluate a miniCEX tool for midwifery education. Methods: Using an action research approach, this project engaged midwifery clinicians and midwifery students to adapt and implement the miniCEX in a postnatal ward environment. Focus groups were held to establish the clinical expectations and develop performance guidelines of students across the domains of midwifery practice, as well as evaluate their use in practice. Findings: Evaluation of the midwifery miniCEX, including its applicability from the perspective of staff and students was positive. The miniCEX was found to be easy to use, time efficient and valuable for learning. Discussion: The miniCEX is an innovative approach to assessment and feedback in midwifery education, and there is currently no identified evidence of its use in midwifery education despite broad use globally in medical education. Conclusion: The implementation of the midwifery miniCEX offers broad benefit to both midwifery students and midwifery clinicians and educators globally.
