What does triangulation in evaluation refer to?

Triangulation in evaluation refers to the use of multiple methods or data sources to enhance the credibility of evaluation findings. This approach is valuable because it helps to increase the validity and reliability of the results. By incorporating various perspectives, including different methodologies, data types, or stakeholder inputs, evaluators can cross-verify information. This process can reveal different dimensions of a particular phenomenon or program, leading to a more comprehensive understanding.

When evaluators employ triangulation, they can identify patterns or inconsistencies across data sources, which are crucial for making informed decisions. It adds depth to the evaluation and reduces the likelihood of biases that may arise when relying solely on one method or source of data. Consequently, the conclusions drawn from the evaluation findings become more robust and well-supported.

The other options focus either exclusively on specific aspects of evaluation or limit the scope to single methodologies, which does not align with the broader concept of triangulation as a means to enrich the evaluation process.
