Determinants of Internal Audit Effectiveness : Evidence from Ethiopia 

The existence of multi-dimensional measures of internal audit effectiveness made the findings of most prior studies inconsistent. The central attention of this study is to identify the determinants of internal audit effectiveness in Ethiopian public higher education institutions, add knowledge to the existing literature, and give direction to practitioners and academicians. To achieve this objective, both qualitative and quantitative research designs were used. Data were collected from internal auditors through a structured questionnaire and interview. The confirmatory factor analysis, structural equation model, and multiple regression model were employed. As the findings of the study denoted, adequate and competent internal auditors, internal audit charter and quality of internal audit work are crucial determinants of internal audit effectiveness. It can be concluded from the study that establishing internal audit charter and improving the adequacy and competency of internal auditors will ensure the independence and objectivity of internal auditors.
