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, the range statement and the Assessment Guidelines for the Training Package. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The candidate should demonstrate the ability to conduct maintenance and repair work on wastewater collection assets by: planning and preparing work site performing maintenance and repair tasks on pipe work and structures according to manufacturer specifications and organisational requirements checking work, restoring work site, storing equipment and completing documentation. |
Context of and specific resources for assessment | Access to the workplace and resources including: documentation that should normally be available in a water industry organisation relevant codes, standards and government regulations. Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit. Questioning will be appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |

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.
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: install and repair appropriate assets clear chokes and blockages maintain assets identify and respond to operational problems use communication systems perform work-based calculations follow drawings, plans, specifications and instructions apply policies and procedures use safety and personal protective equipment work effectively as part of a team use tools and machinery identify hazards communicate with customers and other employees use literacy skills in regard to verbal and written communication in the workplace record work activities. |
Required knowledge: system hydraulics basics system layout system calculations environmental aspects of construction and maintenance lock-out procedures for mechanical and electrical installations relevant utilities and service bodies risk factors and potential hazards of locating underground utilities and services risk factors and potential hazards of installation and maintenance processes hazardous materials handling landscape and ground structure of work area equipment operation, capacity and limitations effects of weather and conditions on construction site or plant control systems pipes and fittings OHS procedures personal work site safety component parts repair and maintenance standard operating 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. Add any 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. | |
Assets may include: | collection system's pipe work, including: vitrified clay reinforced concrete polyvinyl chloride (PVC) polyethylene cast iron cement lined ductile iron cement lined glass reinforced piping mild steel cement lined structures, including: meter pits valve pits drop structures regulators erosion barriers person access chambers and pits head walls thrust blocks inspection shafts controlling equipment fittings, including: jointing systems for pipe types, e.g. gibault tension bands solvent cement joints compression ring joints bolted flanges cathodic protection electrofusion butt-welding. |
Equipment and tools may include: | hand and power tools lifting and winching equipment mechanical excavation equipment local repair by electronic means, including: top hats patches pneumatic and motorised equipment, including: compressors pneumatic spades and attachments motorised cutting equipment conventional and jet rodding systems on- and off-road vehicles portable pumps communication equipment closed circuit television (CCTV) equipment to survey repairs breathing apparatus gas detection equipment rescue equipment appropriate personal protective equipment. |
Legislative and organisational requirements may include: | relevant federal and state or territory legislation and regulations codes of practice, associated standards and guidance material documented organisational policies, manuals and induction programs relevant community planning and development agreements, such as land care agreements. |
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.
