Which description best captures the purpose of triangulation in assessment?

• A. Triangulation uses multiple data sources to corroborate findings.
• B. Triangulation uses a single data source to confirm a hypothesis.
• C. Triangulation eliminates bias by averaging scores.
• D. Triangulation increases the burden on clients.

Answer: (B)

Triangulation in assessment means gathering information from more than one source or using multiple methods so you can see whether findings converge. The aim is to increase confidence in the results by cross-checking evidence from different angles. Different data sources can have distinct biases or blind spots, so when they point to the same conclusion you have stronger support for your interpretation; if they diverge, you spot where more investigation is needed. That’s why using multiple data sources to corroborate findings is the best description. Relying on a single data source can’t provide that cross-validation, and options that rely on averaging or simply increasing client burden miss the core purpose of triangulation.
