Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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 this training package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the design meets the requirements of the standard.

Assessment method and context

Assessment will occur using industrial PB, PEX, PP, Al/PEX composites, PVDF, CPVC and other relevant plastic pipes and components and equipment and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

by use of an appropriate, industrial equipment, situations and polymers

in a situation allowing the generation of evidence of the ability to recognise, anticipate and solve problems

by use of a suitable simulation and/or a range of case studies/scenarios

by a combination of these techniques.

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level required for this unit.

Knowledge and understanding of PB, PP, PEX A1/PEX, PVDF and CPVC materials and pipeline components as described in national standards to recognise suitability for specific application, and to establish work instructions.

Knowledge of detailed work instructions necessary to design high pressure pipelines, and to implement requirements to attain required quality outcomes.

Competence includes the ability to:

identify individual types of materials and components being used

establish specific job needs

establish product selection

set up and maintain safe working environment

establish installation requirements

identify and rectify fault causes arising from application and component variability

establish completion test requirements

establish and maintain quality records

as relevant for the practical completion of work required.

Language, literacy and numeracy requirements

Read material which is sequenced for instructions, explanations, information or opinions.

Write short and simple messages about routine tasks or activities, or complete forms.

Use hands-on real-life materials and pictures/diagrams based on personal experience and prior knowledge.

Use several pieces of related mathematical information.

Read, write and speak whole numbers and money sums, recognise and interpret simple fractions, decimals and percentages, use simple data, grid references.

Use simple grammatical forms and vocabulary to give instructions, give explanations, ask questions and express viewpoints.

Clarify intended meaning by asking for repetition when listening, and varying speed and changing tone or emphasis when speaking.

Use strategies such as providing verbal and non-verbal feedback in order to show interest or attitude.

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. 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.

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This competency unit includes the design of relevant elements of polybutylene (PB), polypropylene (PP), crosslinked polyethylene (PEX), A1/PEX composites, polyvinylidenefluoride (PVDF) and chlorinated PVC (CPVC) pressure pipeline components. The end applications include pipelines used for transmission of water based fluids at elevated temperatures.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards. These may include

AS/NZS 2642

AS/NZS 2492

AS/NZS 4176.

Tools and equipment

This competency includes use of equipment and tools such as:

measurement devices including pressure gauges, times, temperature probes, calipers, and computer based monitors

calculators

relevant safety equipment

comprehensive work instructions.

Hazards

Typical hazards include:

high pressure fluids

hazardous cleaning fluids

pipe material handling

heavy stationary and moving machinery

cutting and heating components.

Problems

Anticipate and solve problems means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.

Typical process and product problems may include

variable material, and pipes and components as supplied

variable field site conditions

limitations in available data on specific job requirements.
