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!

MEM18057B - Maintain/service analog/digital electronic equipment

What evidence can you provide to prove your understanding of each of the following citeria?

Undertake maintenance checks and routine tests

  1. Electronic equipment, functions are determined and understood by reference to circuit diagrams, equipment manuals and/or consultation with equipment operator where appropriate.
  2. Equipment built-in test functions are run and results are recorded to standard operating procedures where appropriate.
  3. Built-in faults/status display is noted and recorded to standard operating procedures.
  4. Equipment/sub-assemblies, components, connections, terminations etc. are checked visually and with correct and appropriate test equipment and techniques.
  5. Faulty components are removed and replaced where appropriate.
  6. All results are checked for compliance with manufacturers' requirements or specification, and results are recorded to standard operating procedures.

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

A person who demonstrates competency in this unit must be able to maintain/service analog/digital electronic equipment. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with maintaining/servicing analog/digital electronic equipment, or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

following relevant circuit diagrams, manuals, specifications, schematics, maintenance records, supplier catalogues etc.

checking electronic equipment/sub-assemblies, components, connections and terminations for conformance to specifications

removing and replacing components from the electronic equipment

isolating electronic sub-assembly from the power supply

adjusting/tuning and calibrating electronic equipment/sub-assemblies
