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

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

Evidence of the following is essential:

correctly blend chemicals for ink and varnish manufacture according to job specifications

demonstrate an ability to find and use information relevant to the task from a variety of information sources

use either a mixer/disperser OR a bead mill OR an automatic ink dispensing system to blend TWO batches of chemicals OR tint TWO batches of ink intermediates/concentrates according to manufacturer's and job specifications, OHS requirements, enterprise procedures and the listed Performance Criteria.

Context of and specific resources for assessment

Assessment must ensure:

assessment may take place on the job, off the job or a combination of these. Off the job assessment must be undertaken in a closely simulated workplace environment.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.

Required Skills and Knowledge

Required skills

OHS in relation to operating machinery such as safely switching off machinery before cleaning is started

communications ideas and information by completing logs and checklists according to enterprise procedures

collecting, analysing and organising information by reading and interpreting job requirements from documentation

planning and organising activities by completing startup checks prior to the blending process

teamwork when contributing to the production process in association with others

mathematical ideas and techniques by mixing batches according to job specifications

problem-solving skills by making adjustments to the mix to maintain quality standards

use of technology by using blending machines and equipment

Required knowledge

OHS considerations when cleaning bowls, vats, and pots

other OHS issues that arise in the blending of chemicals and use of an automated ink dispensing system

safety equipment that is required and what do you need to check when fitting and using it

batch coding system used in the work area and the recording procedures used

procedures for preparing containers and equipment for blending/tinting

checks to be made when measuring chemicals for blending

procedures that apply to adding chemicals according to formulae

purpose and process of homogenisation

purpose of de-ionising water when it is to be used in the blending process

procedures that apply to constructing a correct colour according to a formula

factors that determine the position of the mixing head when blending

procedures for testing conductivity, viscosity and pH, where in-process testing is conducted

sampling and testing process

recording and labelling procedures that apply

environmental issues that need to be considered when working with the range of materials used in chemical blending/tinting

manuals, safety and other documentation that are relevant to this task and where they are kept and information that is included in these documents
