Job performance evaluation (JPE) is a very important strategic tool for organizations because it allows them to measure the performance and development of people in their jobs and their contributions to achieve institutional goals, which ultimately reflect the performance of the institution and the institutional mission accomplishment. Thus, it is so important to have an objective and practical evaluation system that can fulfill these expectations, especially when it’s related to public entities whose main purpose is to meet the needs and to seek the community development, which requires having more productive, efficient and upright public workers who are permanent public value generators. In this context, the work was developed by taking as the object of study the national public entity Servicio Nacional de Aprendizaje SENA Regional Cauca, and aims to formulate a proposal to improve the work performance evaluation process, from the diagnosis of the process and the construction of a theoretical framework that integrates the necessary concepts to understand the importance of this tool and the need to apply it as a key factor in the human talent strategic management and as a strategy for continuous improvement in the entities. The development of the work starts from a general problem related to the JPE identified in some public entities, which is contrasted with the results of the diagnosis, that by the use of tools as the SWOT analysis and the problems and objectives tree, allowed the identification of improvement opportunities and possible determining factors, to finally achieve an improvement proposal focused on strengthening the process and accomplishing the goals stablished by the Comision Nacional del Servicio Civil (CNSC) that at present is just achieved partially, which means that its contribution to the institutional performance improvement and fulfillment of the institutional mission is very low, as it is argued in the present work conclusions.
