Estimated study time: 8 minutes

Learning objective: Choose evidence that matches whether a standard requires knowledge, practical competence or both.

Knowledge-based evidence Competence-based evidence
Explains principles, legislation, physiology, method design or quality theory. Shows safe application during real or appropriately simulated practice.
May use a referenced explanation, case discussion or presentation. May use competency records, observed activity, annotated results or trainer testimony.
Question: can I explain it accurately? Question: can I do it safely and justify my actions?
Example: limitations of an enzymatic creatinine method. Example: responding to an IQC failure under the local procedure.

A theoretical explanation cannot by itself prove that a candidate can carry out a practical task safely. Conversely, a signed competency form may show that a task was observed but may not demonstrate the candidate’s understanding of limitations or patient impact. The strongest portfolio uses the appropriate combination.

When reviewing a proposed evidence item, ask whether the standard needs an explanation, an observed action, an artefact from practice, a reflection on judgement or several of these together.

Learner activity

Take one practical competency and add two short notes: the knowledge that underpins it and the evidence that shows safe application.

Key points

  • Match evidence type to the requirement.
  • Competence standards need evidence of practice.
  • Competency records often need supporting explanation or annotation.
