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, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.

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

Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:

OHS requirements are met

quality improvement techniques are applied

emergency procedures are understood and applied

waste is minimised.

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

Guidance information for assessment

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

Required Skills and Knowledge

Required skills

Required skills include:

using and maintaining all required materials, tools and parts

recognising situations which could cause production problems and taking appropriate action

implementing enterprise's procedures and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the production of fibrous plaster products

diagnosing and solving problems involved in the work

communicating effectively with team members, management and in some cases, clients

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

specified quality standards

characteristics of different materials

requirements from drawings, specifications or job sheets

distinguish between causes of faults such as:

materials faults

dimensional inaccuracies

inappropriate allowance for material shrinkage

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. 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.

Procedures

All operations are performed in accordance with standard procedures and work instructions

Products

Products may include:

ornamental castings including scotias, cornices and arches

centre pieces (both reinforced and un-reinforced)

ornamental recessed panels

Equipment and unit operations

This unit of competency includes all such items of equipment and unit operations which form part of the modelling process. These may include:

slides

templates

reinforcing materials

separation agents

lifting equipment (for large work)

Fibre

Fibre may be glass fibre or other appropriate fibre

Typical problems

Typical problems may include:

incorrect calculations or setting out

inappropriate plaster mixtures

variations in ambient temperature

inappropriate placement of reinforcing or anchor points

Occupational health and safety (OHS)

The identification and control of hazards and the application of OHS is to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements
