Feedback is not useful merely because somebody gave it confidently.
Feedback source calibration is the process of deciding how much weight a correction deserves by judging the source’s expertise, evidence access, independence, domain fit and alignment with the governing standard.
This is the second pillar in the second Feedback quartet beneath How Feedback Works. It owns a narrow decision: when should a learner accept feedback, question it or verify it?
Quick Read
Good feedback depends on more than kindness, seniority or confidence. A source deserves more weight when they understand the domain, have seen the relevant performance, know the standard being judged, can explain the evidence behind the correction and have a reliable track record. Weight should fall when the source is outside the domain, has seen only a fragment, is working from an outdated standard, or has incentives that distort the judgement. Calibration is not cynicism. It is a disciplined way to keep useful authority while preserving the learner’s right to inspect the reason for change.
Expertise Must Match the Job
A brilliant mathematics teacher may not be the strongest source for literary style.
A writing coach may give useful prose advice while lacking authority over a particular examination rubric.
Credibility is domain-specific.
Evidence Access Matters
A teacher who watched the full reasoning process sees more than someone who sees only the final answer.
A marker with the complete script may understand a recurring pattern that a reviewer of one paragraph cannot.
The Governing Standard Matters
A correction can be sensible and still belong to the wrong standard.
For assessment, the rubric and task instructions matter. For publication, the house standard matters. For a laboratory procedure, the validated protocol matters.
Track Record Is Evidence, Not a Substitute for Evidence
A source with a strong history of accurate diagnosis deserves a higher prior level of trust.
But even reliable people can be wrong in a particular case.
When stakes are high, inspect the evidence behind the correction.
Independence Matters When Several Sources Agree
Three tutors may repeat the same interpretation because they all learned from the same marking note.
Agreement is stronger when sources reached the judgement through genuinely separate routes.
Source Calibration and Feedback Conflict Work Together
The first sibling, Feedback Conflict, owns what to do when credible corrections disagree.
Source Calibration helps decide how much each route should count before the disagreement is resolved.
A Practical Calibration Packet
CORRECTION: “Your evaluation is too descriptive.” SOURCE: Subject teacher DOMAIN FIT: High EVIDENCE ACCESS: Full essay + prior essays STANDARD ACCESS: Current rubric EXPLANATION: Points to 3 paragraphs without judgement language TRACK RECORD: Prior corrections improved marks ACTION: High-weight feedback; repair and retest
Evidence Boundary
Feedback research supports the general value of actionable, task- and process-focused feedback, but outcomes vary with how feedback is designed, received and used. The Education Endowment Foundation explicitly advises schools to consider the quality of the evidence, the learner’s response and the opportunity to act on feedback rather than treating all comments as equally effective.
Final Thought: Trust the Correction in Proportion to the Route Behind It
The strongest feedback source is not simply the most confident voice. It is the source with the clearest fit to the task, the best access to the evidence and the most defensible route from observation to correction.
