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

It is essential that the process be understood and that the importance of critical material properties and design characteristics is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

products are made consistently in minimum time and with minimum patching

finishing is within specification/example

good OHS practice is used consistently.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

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

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.

Prerequisite units may be co-assessed if appropriate.

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:

recognising conditions which will lead to out of specification product and taking appropriate action

implementing the enterprise's procedures within time constraints and in a manner relevant to the correct use of the equipment

conveying information relevant to the operation clearly and effectively

maintaining appropriate levels of quality assurance

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

principles of concrete mixing (if mixed by operator)

principles of veneer adhesion

principles of concrete finishing

causes of mould wear

results of using worn moulds

problems resulting from mould leakage

reading steel plans

predicting final shape/dimension based on bar size/type and bend radius

principles of reinforcing concrete to specification

principles of fitting accessories to specification

principles of concrete product finishing

reinforcing materials

design factors

fabrication methodologies

effect of water-cement ratio on product

importance of vibration on compaction

required concrete cover of reinforcing

concrete sampling and testing procedures

non-conformance procedures

underlying causes of faults such as precipitated by:

material inconsistencies

mixing irregularities

finishing difficulties concrete

mould anomalies

casting/operating conditions

concrete mix variations

vibration

aggregate size

reinforcing design/placement

setting/curing time/rate

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

Typical problems

Typical problems may include:

compact product with tight bends/clearances

loss of fluids (concrete leakage)

adjustment to take account of variables such as weather

variations in cement/water ratio

backing concrete penetrating veneers

OHS

All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence
