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 maintain, repair control instrumentation - single and multiple loop control 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 maintaining, repairing control instrumentation - single and multiple loop control 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. |

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 interpreting relevant engineering specifications, technical information, software data, diagrams and drawings, historical records and documents pertaining to the system components and operational data consulting system operators and other relevant plant personnel with respect to the control loop characteristics confirming function/malfunction of the system and/or its components checking operational characteristics of control devices, signal conversion instruments and final control elements for conformance to specification identifying faults/defects in control system components locating/reading in-built fault indicators and error codes obtaining relevant pneumatic, electrical and electronic circuit diagrams testing and monitoring the control loop for correct operation monitoring and recording responses of the control system using appropriate fault-finding and diagnostic techniques and procedures throughout the monitoring and testing process comparing collected data with the operational specifications of the control system marking components for repair or replacement dismantling/disassembling serviceable items setting up appropriate test and calibration equipment setting and adjusting the controller modes checking the control instrumentation for correct zero, span and range adjusting the control system as required completing all necessary reports including appropriate follow-up procedures commissioning the control system interpreting trends from operational data interpreting information from in-built devices calculating control loop characteristics |

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. | |
Historical trends | SCADA, charts, chart recorders and data loggers, equipment condition monitoring etc. |
Control loop | An opened and closed loop system includes final control elements, process measuring devices, converters, controllers, process signals and the like |
Major components can include | Transducers, power supplies, removable circuit boards, sensor units and other like components |
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.
