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:

batches are 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. Simulations may also include the use of case studies and scenarios. A bank of scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

This unit may be assessed in conjunction with:

PMC561080B 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 material 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 conditions which will lead to out of specification product

implementing the organisation's procedures and relevant regulatory requirementswithin time constraints and in a manner relevant to the operation of the equipment

conveying information relevant to the operation clearly and effectively

supervising delivery drivers as required by procedures

numeracy andliteracy to interpret workplace documents and technical information

Required knowledge

Required knowledge includes:

understanding of the equipment sufficient to operate it, recognise potential problems and to take appropriate action

organisation's procedures and relevant regulatory requirements, such as:

principles of operation of batching and mixing equipment

principles of batching and mixing these products

impact of variations in raw materials on the final product

impact of mixing on final product

organisation's production and/or delivery schedules

causes of faults such as those precipitated by:

raw material inaccuracies

equipment failures

mixing time/technique variations

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

Job requirements

Job requirements may be determined from:

work schedule

job specification

job card

batch card

computerised system

other

Sampling and testing

Sampling and testing may be required for:

moisture content

particle size

other

Variations

Variations may include:

nature and type of plant configuration

nature and type of material or product to be batched/mixed

conditions under which the product is to be employed including weather conditions

Typical problems

Typical problems include:

equipment malfunction

raw material specifications

mixing tolerance

uniform dispersion of minor ingredients/additives

mixing to colour/other special requirements

matching mixes produced with production requirements

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

Occupational health and safety (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
