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

Assessment of this unit should include demonstrated competence in a workplace based project or a simulated workplace project.

Access should be available to all normally accessed tables, data etc which would be available to and used by a competent refractory specialist performing this assignment.

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

Competence must be demonstrated in the ability to design an appropriate refractory system and write the required specification.

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

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.

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Manufactured Mineral Products Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods which include direct observation of tasks should also include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

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:

solving problems

communicating at all levels

using organisation knowledge system

analysing

interpreting data

negotiating

technical reporting

technical drawing - possibly computer aided drafting (CAD)

Required knowledge

Required knowledge includes:

properties of all common refractory systems

typical limitations and applications of all common refractory systems

installation methods and their advantages, disadvantages, typical uses and limitations

heat transfer calculations (resistances in series and parallel)

structural calculations (beam, column, arch, strength of refractory materials, and physical properties of refractory materials)

thermal expansion (calculation of and allowance for)

refractory anchors, types, uses and selection

refractory installation methods and their impact on design

common refractory repairs and their impacts on design

methods of reuse, recycling and disposal of refractories at the end of their life and the differences for different types of refractory systems

critical refractory specifications

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. 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.

Stakeholders

Stakeholders may include:

customer representatives

technical experts

regulators

refractory designer

refractory installer

End use conditions

End use conditions may include:

surface temperature of refractory

required temperature gradient through refractory/outside surface temperature

chemical condition (e.g. pH)

mechanical condition (e.g. impingement)

temperature or other cycling

Types of refractory installations

Typical types of refractory installation include:

block/precast

monolithic/castable

gunite/shotcrete

refractory coating

multilayer refractory linings (e.g. hard face over insulating refractory)

Ranking of refractory system solution

Ranking should be based on:

how well they meet the technical requirements of the end use

HSE risks

HSE risks should include focus on the comparative health, safety and environmental risks of the refractory systems under consideration.

Risks would include risks during:

installation

use

repair

removal and disposal at end of life

Cost of refractory systems

Cost of refractory systems should be total costs and should include:

material costs

installation costs

repair costs

life cycle costs

Optimum refractory system

The optimum refractory system would be:

that system which best delivers the technical requirement at the lowest cost and the least HSE risk
