Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of ability to:

handle chemicals safely

demonstrate wastewater system operating procedures

demonstrate first flush system operating procedures

conduct water quality tests

take corrective action in response to out-of-specification results or non-compliance

monitor supply and quality of waste water

report and/or record corrective action

demonstrate emergency procedures

demonstrate shift handover procedure

demonstrate an operational shut down procedure.

Context of and specific resources for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

Waste water treatment systems and related chemicals

Test equipment

Relevant advice on environmental agreements

Operating procedures and related advice on equipment operation

Personal protective clothing and equipment

Communication systems and equipment

Housekeeping standards and procedures

Workplace information recording systems, requirements and procedures.

Method of assessment

Other units of competency relevant to the work role should be assessed in conjunction with this unit.

Guidance information for assessment

To ensure consistency in one's performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.
