As the volume of Korea’s official development assistance (ODA) expands, the demand for systematic management of evaluations and improvement of their usefulness is increasing. This study focuses on developing evaluation methodology for technical cooperation (TC) which is an important part of Korea’s ODA. Based on the case studies of six multilateral organizations and four bilateral development agencies, we draw lessons for Korean ODA agencies in terms of selection criteria, types, and methodological aspects of evaluation of technical cooperation and propose a four-step project management and evaluation mechanism for TC activities.
