This article explains the Verifier Body (VB) and Verifier scores, factors that improve scores, and the associated VB ‘risk levels’ that determine the activities implemented by SLCP to ensure high quality data.
- Individual Verifier Quality Scores
- Verifier Body Quality Scores
- Managing Quality Scores
- Verifier Body Risk Levels & Corrective Actions
All Verifiers and VBs are monitored by SLCP. SLCP assigns a score to Verifiers and VBs as part of our Integrity Oversight Program.
Both Verifiers and VBs receive an individual score that reflects their performance. A Verifier’s score is one element that influences a VB’s score. VBs are expected to address individual Verifier performance issues in order to improve their own score.
VB and Verifier scoring incentivizes strong performance to ensure high quality verifications, while also empowering facilities to make informed choices when selecting a VB.
Individual Verifier Quality Score
An Individual Verifier Quality Score is the metric used to track the performance of each Verifier.
Verifiers are scored between 0 and 5, with 5 being the highest score. This score is calculated by taking the total number of mistakes (‘quality issues’) associated with a Verifier’s assessments, and dividing it by the total number of verifications the verifier has conducted. Verifications with no mistakes will result in a higher score, and those with mistakes will result in a lower score.
Only verifications from the last 12 months will count towards an Individual Verifier Score.
VB Quality Scores
The Verifier Body (VB) Quality Score is the metric used to track the quality performance of each VB.
The VB Quality Score is calculated using the following elements:
-
A Management System Check
This is a mandatory check, conducted every three years. It ensures that a VB has the correct systems, trainings and policies in place, reflecting SLCP requirements. -
A weighted average of Individual Verifier Scores
An Individual Verifier Quality Score is the metric used to track the performance of each Verifier. The VB score takes a weighted average of Individual Verifier Scores, based on how many verifications they have conducted. This means Verifiers with more verifications will have a higher impact on the overall weighted score. -
A VB issue to verification ratio
This ratio monitors the number of mistakes at a VB within the last 12 months. It is calculated by dividing the number of quality issues by the total number of verifications. The calculation also considers how serious and how often those quality issues occur.
These three elements make up a single score between 0 and 5 that determines a VB’s performance, with 5 being the highest. The scores will be displayed on the public VB Active List on 1 January 2026.
Managing Quality Scores
VBs should aim to improve their score as it impacts their risk level and their likelihood of appearing on the ‘Selection List’ for facilities.
A VB’s score can be improved by:
- Addressing individual Verifier performance issues so that they are conducting more verifications without mistakes
- Resolving quality mistakes or concerns quickly and adequately
- Ensuring all Verifiers are trained and are up to date on the latest SLCP guidance and calibrations. Regularly check the VB dashboard for important announcements and to track scoring.
VB Risk Levels & Corrective Actions
The VB Score is used to determine the risk level of each VB, monitored through the ‘Integrity Oversight Program’. SLCP ensures that actions are taken based on each VB’s assessed level of risk.
All VBs and Verifiers are monitored by SLCP. Those with lower scores have extra quality assurance activities applied based on their risk level.
SLCP has four risk levels, and different interventions are applied at different levels, once a VB has remained at that level for a certain period. The levels are:
| Risk level | Score | Interventions |
| Low Risk | Score 4 or higher | VBs are encouraged to keep high performance. |
| Medium Risk | Score between 3 and 4 | VBs are given a monthly performance summary. |
| High Risk | Score between 2 and 3 |
VBs are issued a management system 'Corrective Action Request’, and SLCP conducts a Desktop Review. If a VB does not show improvement, they may be placed on probation, suspended, or terminated. |
More information is available in the Scoring Model Concept Note, available to VBs on their individual VB Dashboard.
