Certified Theory of Change (CTOC) is a professional certification program that equips participants with knowledge and practical skills in applying the Theory of Change (TOC) methodology for systematic project planning, implementation, monitoring, and evaluation.

Theory of Change (TOC) is a systematic planning and evaluation methodology that explains how and why a desired change is expected to occur within a specific context. It provides a structured framework for identifying long-term goals and mapping the sequence of activities, outputs, outcomes, and impacts required to achieve those goals. The approach also identifies assumptions and external factors that may influence the success of a project or program.

TOC helps project managers and stakeholders establish clear logical relationships between project interventions and expected outcomes while ensuring that project activities are aligned with strategic objectives. By defining measurable outcomes and explicitly identifying the assumptions underlying each stage of change, TOC supports effective project planning, implementation, monitoring, and evaluation. Consequently, the application of Theory of Change enhances project effectiveness, accountability, and the achievement of sustainable development outcomes throughout the project life cycle.
