Triangulation means using more than one source to reduce misreadings. It is how leaders avoid chasing the wrong problem.

Why triangulation matters
One dataset can mislead. A second source adds context. A third source helps you decide.

Common triangulation pairs

• Assessment trend + student work samples

• Attendance trend + behaviour incidents

• Survey themes + counselling trends

• Walkthrough notes + learning outcomes

What triangulation does not mean
It does not mean collecting everything. It means selecting only the evidence that will help you decide.

A practical approach
For any pattern, ask:

• What other source would support this?

• What other source might contradict it?

• What would I expect to see if the pattern is real?

Key Takeaways

• Triangulation protects time and credibility.

• Use it to confirm or challenge assumptions.

• Limit yourself to two or three sources.

Quick Check

Choose one pattern you are seeing. Name two sources that would help you confirm it.
