Moderation

The process of reviewing and standardising evaluation scores across different assessors to ensure consistency and fairness in procurement scoring.

How it works

Moderation involves a systematic review of evaluation scores assigned by different assessors during the procurement process. A moderation panel, typically comprising senior procurement staff and subject matter experts, examines scoring decisions to identify and address inconsistencies between evaluators.

The process usually occurs after initial scoring but before final award decisions. Moderators review scores against evaluation criteria, challenge assessments that appear inconsistent with the evidence, and ensure all evaluators have applied scoring methodologies uniformly. They may request assessors to revisit and justify their scores, particularly where significant variations exist for similar responses.

Why it matters

Moderation is essential for maintaining procurement integrity and legal defensibility. Without proper moderation, scoring inconsistencies can lead to unfair outcomes, successful legal challenges under the Public Contracts Regulations 2015, and damage to the contracting authority's reputation.

The process helps ensure that all suppliers receive fair treatment regardless of which evaluator assessed their submission. It also provides an audit trail demonstrating that procurement decisions were made objectively and consistently, which is crucial if the process faces scrutiny or challenge.

Best practice

Effective moderation requires clear scoring guidance, trained moderators with appropriate authority to require score changes, and sufficient time allocation within procurement timescales. The moderation process and any score changes should be fully documented to demonstrate transparency and accountability.
