This paper is the result of a joint pilot exercise of the “Toolkit for identifying, monitoring and evaluating the value added of triangular co-operation” among the EU-LAC Facility for Triangular Co-operation (ADELANTE) and the OECD. The eight projects of the ADELANTE Facility worked with the questionnaire of the evaluation tool to assess the value added of working in a trilateral partnership. The EU team and the projects agreed that the six areas identified as potential value added of triangular co-operation are valid for ADELANTE. The joint pilot exercise was insightful and inspiring for all of the partners involved as an instrument for mutual learning. The recommendations arising from this joint exercise will contribute to the design of future EU triangular co-operation initiatives, aiming to make good use of the value added of the modality and addressing the challenges in a constructive, forward-looking way.
