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 competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

identify critical materials properties and roller building process characteristics in relation to the process requirements and the end product

plan own work process within workplace procedures and explain the reasons for the steps in the process

take appropriate action to observe equipment, materials and products for out of specification results, make adjustments and identify problems to be reported

Consistent performance should be demonstrated. For example, look to see that:

production quality and output standards are met consistently

problems are anticipated from process observations

problems are efficiently resolved

the process runs consistently and smoothly.

Assessment method and context

Assessment will occur on industrial roller building equipment in a work-like environment.

Competence in this unit may be assessed:

by using appropriate, industrial roller building equipment

in a situation allowing for the generation of evidence of the ability to respond to problems

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

through 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.

Application of knowledge of the materials, equipment and process sufficient to recognise material and equipment conditions which may lead to out of specification production.

Knowledge of organisation procedures and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.

Application of the knowledge of managing risks using the hierarchy of controls applied to the roller building process. Application of approved hazard control, safety procedures, the use of PPE in relation to handling materials, equipment operation and clean-up.

Knowledge as a basis for solving processing and material problems, including:

identifying the function of roller building equipment, machine components and the materials used

identifying faulty cores/mandrels

describing changes to materials at the stages of production conducted by the employee

explaining the impact of roller building machine temperature, pressure and adhesive flash off time on product quality and production output

identifying and describe own role and the roles of others involved directly in the roller building process

deciding if they (the operator) are able to rectify the fault or if assistance is required

explaining the effect of unauthorised or emergency shutdown of equipment on the roller building process

explaining the nature of the mechanical, hydraulic, pneumatic, electrical and electronic principles which influence the roller building equipment operation and product development

explaining the impact that chemical reactions/mechanical processes have on changing the state, form and condition of the materials

polymer properties and their interactions with process conditions

relationships between polymer properties and process conditions

changes to polymer properties to better suit process requirements.

product problems related to polymer properties

product problems related to process conditions

adjustments to process conditions to meet polymer and product requirements.

Competence also includes the ability to:

plan own work sequence, including identification of key checkpoints for equipment monitoring, product quality checks and monitoring of supplies and downstream operations monitor equipment operation and product quality

identify factors which may influence product quality and production output and appropriate remedies

make appropriate authorised alterations to own work plan and equipment to maintain both product quality and required production output

locate, interpret and apply relevant information and maintain workplace records

identify and safely handle products and materials, read relevant safety information and apply safety precautions appropriate to the task

apply and/or explain impact of incorrect or faulty materials.

Language, literacy and numeracy requirements

This unit requires the ability to read and interpret typical product specifications, job sheets and material labels as provided to operators.

Writing is required to the level of completing workplace forms.

Basic numeracy is also required to interpret specifications and lay out geometric shapes.

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
