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 equipment be understood and that the importance of critical material properties and mixing variables 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:

product is produced on time and in specification

upstream and downstream communication is timely and effective

problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).

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

This unit may be assessed in conjunction with:

PMC561080A Organise self

MSAPMSUP106A Work in a team.

Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes. In remote operations, this person may also need scheduling and other materials ordering and handling competencies.

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 potential problems and taking appropriate action

implementing the enterprise's standard procedures and work instructions and relevant regulatory requirements within appropriate time constraints and in a manner relevant to the operation of the equipment

reading and numeracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

principles of drying of aggregates

principles of mixing these products

impact of variations in raw materials on final product

impact of mixing on final product

enterprise production schedules

distinguish between causes of faults such as:

raw material

equipment

mixing time/technique

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

Aggregate

Aggregate may include:

the normal range of gravels and sand as well as recycled asphalt pavement (RAP)

It may, or may not, include the addition of special aggregates such as slag, carborundum, lime or crushed garnets

Typical problems

Typical problems may include:

equipment malfunction

raw material specifications

mixing tolerance

uniform dispersion of minor ingredients/additives

mixing to special requirements

matching mixes produced with production requirements

adjusting mix formula to compensate for variations in raw materials (e.g. aggregate moisture content)
