Evidence Required

This provides essential advice for assessment of the competency standard unit and must be read in conjunction with the Performance Criteria and the Range Statement of unit and the Training Package Assessment Guidelines

The Evidence Guide forms an integral part of this competency standard unit and shall be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment

Longitude competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the Industrys preferred model for apprenticeships However where summative or final assessment is used it is to include the application of the competency in the normal work environment or in a realistically simulated work environment It is recognised that in some circumstances assessment in part or full can occur outside the workplace However it must be in accord with Industry and regulatory policy

Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed

The critical safety nature of working with electricity electrical equipment gas or any other hazardous substancematerial carries risk in deeming a person competent Hence sources of evidence need to be rich in nature so as to minimise error in judgment

Activities associated with normal every day work have a bearing on the decision as to how much and how detailed the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practiced These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included in the Assessment Guidelines of this Training Package

Critical aspects of evidence required to demonstrate competency in this unit

Before the critical aspects of evidence are considered all prerequisites shall be met

Evidence for competence in this unit shall be considered holistically Each element and associated Performance Criteria shall be demonstrated on at least two occasions in accordance with the Assessment Guidelines UEP Evidence shall also comprise

A representative body of work performance demonstrated within the timeframes typically expected of the discipline work function and industrial environment In particular this shall incorporate evidence that shows a candidate is able to

Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the Performance Criteria and Range Statement

Apply sustainable energy principles and practices as specified in the Performance Criteria and Range Statement

Demonstrate an understanding of the essential knowledge and associated skills as described in of this unit

Demonstrate an appropriate level of employability skillsConduct work observing the relevant Anti Discrimination legislation regulations polices and workplace procedures

Demonstrated performance across a representative range of contexts from the prescribed items below

The knowledge and application of relevant sections of Occupational Health and Safety legislation Statutory legislation Enterprisesite safety procedures Enterprisesite emergency procedures

Preparation and planning of work

Verification techniques

Diagnostic and fault finding techniques and procedures

Where appropriate attainment of an appropriate electrical licence deeming competency associated with electrical work

Repair techniques and procedures

Completion of work procedures

Dealing with an unplanned event by drawing on essential knowledge and skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items

Context of and specific resources for assessment

This unit should be assessed as it relates to normal work practice using procedures information and resources typical of a workplace This should include

OHS policy and work procedures and instructions

Suitable work environment facilities equipment and materials to undertake actual work as prescribed by this unit

Competency Standards should be assessed in the workplace or simulated workplace and under the normal range of workplace conditions

Assessment of this unit will be supported with documentary evidence by means of endorsement stating type and application of work

In addition to the resources listed above in Context of assessment evidence should show competency working in limited spaces with different types of plant and equipment as well as different structuralconstruction types and methods and in a variety of environments

Method of assessment

This unit shall be assessed by methods given in Assessment Guidelines

Note

Competent performance with inherent safe working practices is expected in the Industry to which this unit applies This requires that the specified essential knowledge and associated skills are assessed in a structured environment which is primarily intended for learningassessment and incorporates all necessary equipment and facilities for learners to develop and demonstrate the essential knowledge and skills described in this unit

Concurrent assessment and relationship with other units

There are no recommended concurrent assessments with this unit however in some cases efficiencies may be gained in terms of learning and assessment effort being concurrently managed with allied competency standard units where listed

Range Statement

10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance.

Inspection should be planned with the appropriate parties to determine access, conditions and work requirements.

Equipment may refer to PLC’s, I/O modules, VDU’s, DCS equipment, communication devices, alarms, stabilised power units and uninterrupted power supply units.

Materials may refer to insulation tapes, heat shrink, sleeving, spiral binding, cable ties, solder, sealants, lugs, connectors, terminal blocks, cable markers and identification labels.

Components may include fuses/circuit breakers, timers, contactors, contacts, coils, relays, resistors, inductors, capacitors, bridge rectifiers, diodes, heat sinks, solenoids, overloads, plug in printed circuit boards, switches, plugs, cable and thermistors.

Test and measurement instruments may include laptop computer, control system interface devices, multimeters, tong testers, insulation resistance/continuity tester, data loggers, overload injection tester, cathode ray oscilloscope, variac, hand held programmer, frequency generator, voltmeters and ammeters.

Fault finding and diagnostic techniques may include linear approach, half split rule, sensory detection and insulation/continuity tests.

Tests and operational checks may include correct air circulation, drainage, vibration, correct temperature, noise, pressure checks and leak detection.

Work may be performed with equipment on line.

Work completion details may include plant and maintenance records, job cards, check sheets and on device labelling updates.

Work site environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water and chemical.

Isolations can refer to electrical/mechanical or other associated processes.

Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries.
