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

A person who demonstrates competency in this unit must be able to set and edit computer controlled machines/processes. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

Context of and specific resources for assessment

This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with setting and editing computer controlled machines/processes or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning should not require language, literacy and numeracy skills beyond those required in this unit. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning and sequencing operations

checking and clarifying task related information

attaching ancillary devices

mounting work holding devices

measuring tool offsets

entering and verifying tool offsets

producing and checking first-off samples

editing programs

instructing machine operator on the sequence of operations

following safety procedures

identifying worn or damaged tooling and taking appropriate corrective action

Required knowledge

Look for evidence that confirms knowledge of:

ancillary equipment and its applications

procedures for attaching the ancillary device(s) to the NC/CNC machine

work holding devices, their application and procedures for mounting them

location of work holding fixtures/devices/tools relative to the machine zero or datum

reasons for establishing tool offsets

procedures and devices for measuring tool offsets

procedures for entering and verifying tool offset

procedures for adjusting tool offsets

operating procedures

safety features and equipment

measuring devices/ techniques for checking the parts or product

effects of changes to cutting feeds and speeds

the impact of changes to the sequence of operations on the part or product to be produced

procedures for editing programs via the machine controller

the sequence of operations of the machine/process

examples of worn or damaged tooling

the effects of worn or damaged tooling

the corrective action to be taken for worn or damaged tooling

hazards and control measures associated with computer controlled machines, including housekeeping

safe work practices and procedures

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.
