Triangulation of Evidence: Why It's Important
Triangulation means backing up your evidence from more than one angle, so your evidence base stands up to scrutiny.
Rather than relying on a single document or data point, inspectors build their judgement from multiple sources: reviewing documents and data beforehand, then gathering first-hand evidence on the day through learning walks and discussions with leaders, staff and pupils. A judgement only feels secure when these different sources tell a consistent story.
The same logic applies to your evidence base. A policy document stating something is in place is a good start, but it's stronger when it's backed up by something that shows it in action, minutes, learning walk notes, pupil survey results, or a leader's report demonstrating impact.
When you're building your evidence base in Intelligent Evidence, it's worth asking whether a grade descriptor has more than one type of evidence behind it. A policy plus an example of it working in practice will always tell a more convincing story than either on its own.
