Elements of Competency Performance Criteria              
Element: Determine system specifications and characteristics
  • Complex circuit/system function and characteristics are determined with reference to circuit diagrams, specifications, schematics and/or consultation with technical adviser.
  • System specifications and operational data is obtained, read and interpreted.
  • Findings are verified using correct and appropriate techniques, procedures, tools and test equipment.
  • Results are recorded and analysed to determine appropriate modification.
       
Element: Modify circuits and systems as required
  • Modifications are undertaken as determined to standard operating procedures.
       
Element: Test modification
  • Modifications are tested and monitored to assess suitability.
  • Modifications are documented in accordance with standard operating procedures.
       


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 modify complex electrical circuits and systems. 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 modifying complex electrical circuits and systems, 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

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

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:

determining appropriate system modifications

analysing

facilitating multiple processes

obtaining and interpreting relevant circuit diagrams, flow charts, specifications, schematics, engineering data sheets, etc.

recording/reporting

testing and monitoring electrical circuit/systems

high level communicating

undertaking calculations using formulae

entering routine and familiar information onto proformas and standard workplace forms

locating, reading and interpreting information on written job instructions, specifications, drawings, charts, lists and other reference documentation

planning, sequencing operations

checking and clarifying strategies

Required knowledge

Look for evidence that confirms knowledge of:

system interrelationship and dynamics

operation of complex electrical circuit/system

implications of modifications to system including hazards

operational specifications of the circuit/system

common electrical test instruments and their application

appropriate test equipment and its application to the testing of the modified circuit/system

the reporting/recording requirements associated with the modification of complex electrical circuits and systems

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

relevant hazards and control measures related to the competency

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.

Complex electrical circuits and systems

Industrial control systems, automatic process machines, material transfer systems, distribution systems, complex control panels etc. incorporating a range of circuit protective devices, relays, timers, transformers, sensors etc.

System

A system's circuit is defined as one that interconnects between a number of interdependent apparatus

Test equipment

Continuity testers, ammeters, voltmeters, multimeters, tong testers, wattmeters, cathode ray oscilloscope, etc.

Documented

All modifications recorded or incorporated into drawings, schematics, 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.
