Assessor Criteria

To demonstrate competence at assessing trainees (against the Level I Clean facilitator criteria), giving suitable feedback, and managing the assessment process.


Have demonstrated a high-level of facilitation skills* in the clean processes being assessed.

The key skills required are to:
1. Provide clear instructions on the assessment activities and what is required of trainees.
2. Recognise when a trainee is demonstrating the criteria (and when they are demonstrating not meeting the criteria).
3. Know when a criterion has been demonstrated sufficiently/enough (or not).
4. Deliver respectful feedback (written and verbal) and an ongoing assessment in a supportive style that clearly specifies:
a. what has been demonstrated
b. what still needs to be demonstrated to meet the criteria.
5. Recognise when feedback has (and has not) been implemented.
6. Weigh up all the evidence and, in discussion with at least one other assessor, come to a final assessment of overall competency based on that evidence.
7. Deliver the final assessment in a way that supports the development of the trainee (and as required responds to trainee objections and concerns).

* e.g. the as-yet-unspecified Level II Clean Facilitator competency criteria.
