Standardisation

20 min

Simple Explanation

Standardisation ensures all assessors apply assessment criteria and mark schemes consistently. It involves training, calibration, and ongoing monitoring to maintain marking standards.

Professional Definition

Standardisation is the process of training assessors to apply mark schemes consistently. It includes reviewing exemplar responses, discussing borderline cases, calibrating judgments, and monitoring consistency throughout the marking period.

Explain It to a 10-Year-Old

Standardisation is like tuning musical instruments before a concert. If every instrument is tuned differently, the music sounds terrible. Standardisation ensures every marker is "tuned" to the same standard.

Why It Matters

Without standardisation, marking drifts. Some markers become harsher; others more lenient. The same learner could pass or fail depending on who marks their paper — fundamentally unfair.

Step-by-Step Process

1

Prepare standardisation materials

Exemplar scripts at different levels

2

Conduct standardisation meeting

Markers calibrate judgments to agreed standard

3

Monitor during marking

Sample checks to detect drift

4

Provide feedback

Correct markers who deviate from the standard

5

Document the process

Evidence of standardisation for regulatory purposes

Worked Example

Digital Administration standardisation:
1. All markers receive mark scheme and exemplar responses
2. Markers independently mark 10 sample scripts
3. Results compared at standardisation meeting
4. Differences discussed; consensus on borderline cases
5. Markers calibrated to agreed standard
6. Ongoing moderation sampling during live marking
7. Drift identified and corrected through feedback

Common Mistakes

Mistake	Problem	Better Approach
Skipping standardisation	Different markers apply different standards	Always standardise before live marking begins
One-off standardisation only	Standards drift over time	Ongoing sampling and feedback throughout marking
Poor exemplar materials	Exemplars must clearly illustrate different levels	Invest in quality exemplar preparation

Checklist

Standardisation materials prepared?
Exemplar scripts at key grade boundaries

Calibration meeting conducted?
All markers attended and calibrated

Ongoing monitoring planned?
Sample checks during marking

Drift correction process in place?
How will inconsistent markers be corrected?

Summary

Standardisation calibrates markers to a common standard
Essential for inter-rater reliability
Typically involves exemplar scripts and calibration meetings
Ongoing monitoring prevents drift during live marking
Poor standardisation = unfair outcomes for learners
