The concept of competence has recently been a hot topic in science management, particularly human resource management. However, most of the studies conducted on this topic have mainly been theoretical. Thus, the present study aims to operationalize competence management through the construction and validation of a questionnaire intended for Tunisian project managers. To this end, a quantitative study is conducted among 156 respondents. The principal component analysis and Cronbach's alpha calculations were used to ensure the validity and reliability of the factor structures. The results of the factor analysis confirm the existence of a measurement scale of competence management that comprises five independent dimensions, namely recruitment, assessment, training, compensation, and career management. This study provides project managers with a measurement instrument that can be used to analyze competence management practices in their companies so that they can develop and enhance their employees’ skills.
