Ethics is an inherent dimension to social work from the beginning, and remains so today, especially given the glaring inequalities and injustices that are detected today. A professional answer must be able to articulate diverse elements of its practice, with a need for ongoing review of both, knowledge and act marked by excellence. As such, this article reflects the ethical dimension in Social Work, mainly in terms of the possibilities to assess their ethical performance. To this end, we resort to the proposed "ethical indicators" of Spanish philosopher Juan Carlos Siurana, from which substantive elements can be released for an own configuration of social work indicators. Key ideas, specificities and essences of these indicators are included in a set of reflections that accompany the system of indicators to which reference is made.
