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 fault find and repair/rectify complex electrical circuits. 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 fault finding and repairing/rectifying complex electrical circuits, 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: using diagnostic skills to identify and correct faulty operation managing multiple processes interpreting and using relevant circuit diagrams, specifications, schematics locating reading/recording built-in fault indicators interpreting error code documents isolating electrical circuits from the power supply tagging isolated circuits verifying circuit isolation confirming/localising circuit faults using appropriate test equipment, work techniques and tools recording/reporting faults in electrical circuits repairing/adjusting electric circuits confirming circuit/s against specification recording rectification of the circuit(s) |
Required knowledge |
Look for evidence that confirms knowledge of: circuit characteristics hazards associated with the electrical circuit(s) relevant regulatory requirements errors indicated by built-in devices circuit isolation procedures common electrical test instruments and their application common techniques for testing electrical circuits recording/reporting requirements for electrical circuit faults appropriate techniques/procedures for returning the circuit/s to specification site/manufacturers' circuit specifications requirements for recording circuit rectifications 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. | |
Circuit | A complex circuit is defined as interdependent circuits |
Appropriate techniques | Testing for voltage, current, frequency, polarity, phase, phase rotation, circuit continuity, insulation resistance, earth continuity etc. |
Test equipment | Continuity testers, ammeters, voltmeters, multimeters, tong testers, wattmeters, cathode ray oscilloscopes, etc. |
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.
Observation Checklist
| Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice | Yes | No | Comments/feedback |
|---|---|---|---|
| Circuit/system function and characteristics are determined by reference to circuit diagrams, specifications, schematics and/or consultation with technical adviser. | |||
| Where appropriate, built-in fault indicators and error codes are examined and correctly interpreted, and results are recorded to standard operational procedures. | |||
| Where appropriate, circuit(s) are correctly isolated from power supply. | |||
| Faults are verified or localised using correct and appropriate techniques, procedures, tools and test equipment. | |||
| Faults are recorded to standard operating procedures. | |||
| Circuit/system is repaired, replaced or adjusted to specifications or manufacturers' requirements using correct and appropriate techniques, procedures, tools and equipment. | |||
| Circuit/system is checked and tested using correct and appropriate techniques, procedures, tools and equipment for compliance with site or manufacturers' specifications. | |||
| Where appropriate, repair/rectification report is recorded to standard operating procedures. |
