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.
