Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 diagnose and repair analog equipment and components. 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 diagnosing and repairing analog equipment and components, 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. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: obtaining and following relevant circuit diagrams, manuals, specifications, schematics, maintenance records, supplier catalogues, etc. locating, reading/recording and diagnosing built-in fault indicators obtaining error code interpretation documents running test functions and recording faults and/or equipment status indicated by built-in test functions/displays checking electronic equipment/sub-assemblies, components, connections and terminations for conformance to specifications removing and replacing/repairing faulty components from the electronic equipment recording results of tests undertaken on electronic equipment isolating electronic sub-assembly from the power supply adjusting/tuning and calibrating electronic equipment/sub-assemblies returning to service and testing to specification the repaired electronic equipment/sub-assembly using language and literacy skills to provide brief reports/records/results of tests reproducing fault symptoms in the electronic equipment and verifying faults using appropriate test equipment and fault finding techniques refitting repaired/replaced components into the sub-assembly |
Required knowledge |
Look for evidence that confirms knowledge of: analogue electronics including amplifiers, oscillators, power suppliers, filters the function(s) of the electronic equipment/sub-assembly symptoms of the fault in the electronic equipment/sub-assembly the purpose of reproducing electronic equipment/sub-assembly fault symptoms equipment and techniques to be used to test the faulty sub-assemblies/component probable causes of component failure procedures for: running built-in test functions verifying faults in electronic equipment/sub-assemblies isolating electronic equipment/sub-assemblies removing sub-assemblies from electronic equipment testing faulty sub-assemblies removing faulty components from electronic equipment fitting repaired/replaced components into sub-assemblies fitting repaired sub-assemblies into electronic equipment testing electronic equipment/sub-assembly performance errors indicated by built-in devices test equipment and fault finding techniques necessary to confirm electronic equipment/sub-assembly faults hazards associated with electronic equipment/sub-assemblies including electro-static discharge (ESD) tools and techniques to be used to remove/refit/repair/replace the faulty sub-assemblies/component from the electronic equipment operational specifications of the sub-assembly operational specifications of the electronic equipment/sub-assembly/component test equipment and techniques necessary to check electronic equipment/sub-assembly performance any applicable industry standards, national/Australian standards, NOHSC guides, State/Territory regulatory codes of practice/standards use and application of personal protective equipment safe work practices and procedures |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Fault finding techniques | Signal injection, substitution, monitoring, measurement, heating, sound, visual, touch, smell |
Test equipment | Continuity testers, ammeters, voltmeters, cathode ray oscilloscopes, frequency counters, signal generators, digital probes |
Components | Discrete component assemblies or individual components such as resistors, switching devices, capacitors, transformers, solenoids, tubes, semi-conductors |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
