What is triangulation in evaluation?

Triangulation in evaluation refers to the use of multiple methods or data sources to cross-verify findings. This approach enhances the credibility and validity of the evaluation results by ensuring that they are not solely reliant on one perspective or methodological approach. By integrating different viewpoints—such as quantitative data and qualitative insights—evaluators can obtain a more comprehensive understanding of the program being assessed. This process helps to identify inconsistencies or corroborate findings, thereby enriching the overall analysis and providing more reliable recommendations.

In research and evaluation, relying on a single method or data source can lead to biased or incomplete conclusions. Triangulation, therefore, serves as a crucial method to enhance the robustness of evaluations, as it allows evaluators to see the whole picture and draw more informed conclusions based on a well-rounded evidence base.
