Abstract: The Health Practitioners Competence Assurance Act 2003 requires nurses to have evidence to support they are competent to practice. Many nurses have become distraught and / or angry at this prospect, and the researcher suggests that this response appears to be more commonly related to the expectation of undertaking reflective writing, which is a key component of the competence evidence. This study explores the predisposing factors relating to nursing, reflective writing and competence to determine how this may impact on a nurse's self esteem. Utilisation of Critical Social Theory informed by feminist framework allows for exploration of the historical, social, political and cultural factors that shape and form female nurses reality in practice. It is a theory that relates to oppression and power, with the primary intent being to raise consciousness in order to emancipate. Although no definitive findings were made, there are multiple factors relating to nurse's history, socialisation, political imperatives and cultural beliefs that have the potential to impact on their self esteem. Competence, competence assessment and reflective practice are complex, therefore presenting multiple challenges. In order for nurses to understand their contextual reality and opportunities for change there is a need for them to engage in critical reflection.
