Quality of Evidence

What Is Quality Evidence?

Evidence is any material, observation, or document that proves a candidate possesses the skills, knowledge, and understanding required by a vocational standard. High-quality evidence leaves no doubt regarding a candidate's workplace capability.

The Three Categories of Assessment Evidence

Assessors gather evidence from three distinct sources to build a holistic picture of learner competence:

• Direct Evidence: Gathered directly by the assessor during real-time performance. Examples include direct workplace observations, structured professional discussions, and oral questioning. Direct evidence carries the highest level of trust.
• Indirect Evidence: Work produced by the candidate or documented by qualified third parties. Examples include completed work products, project plans, reports, and witness testimonies from workplace line managers.
• Supplementary Evidence: Additional supporting documentation, such as certificates of prior achievement, continuous professional development (CPD) logs, and professional memberships.

The Four Essential Rules of Evidence (VARS)

To be accepted by an assessor or quality assurer, all submitted evidence must satisfy four strict criteria, known collectively as the VARS principles:

• Valid: The evidence must relate directly to the assessment criteria being claimed. It must mirror real workplace standards and requirements.
• Authentic: The evidence must be unquestionably the candidate's own work. Assessors verify authenticity through signed declarations, witness sign-offs, and professional discussions.
• Current: Evidence must reflect contemporary working practices and current regulations. Outdated evidence — typically work older than two years — may require updating or supplementary observation.
• Sufficient: The portfolio must contain enough evidence to prove consistent, repeated competence over time, rather than a single accidental success.

How Assessors Evaluate Evidence & Common Pitfalls

Assessors use holistic assessment strategies to cross-reference single pieces of evidence against multiple assessment criteria. This approach reduces candidate workload while ensuring thorough coverage.

Common pitfalls that candidates should avoid include submitting unverified documents, failing to cross-reference evidence to criteria, presenting outdated work products, or relying on witness testimonies from unqualified sources.
