CPDE has developed the modules for member and partner CSOs, especially those working at the national or country level, to support their capacity development efforts. 

By using these materials in training or learning sessions, CPDE aims to equip CSOs in managing programmes particularly for EDC advocacy, in organising and managing networks for EDC based on a human-rights based approach to development and other key CPDE principles, and in launching and sustaining advocacy campaigns especially on development cooperation. This way, CPDE also promotes CSO development effectiveness, as part of its commitment to the Istanbul Principles.
