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 measure components using a coordinate measuring machine in accordance with instructions.

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 on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then 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 measuring components using a coordinate measuring machine 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 techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. 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 and following routine, familiar information for loading, setting probes and measuring components

identifying and following pre-start check procedure

following safety procedures

selecting specified fixture/clamping device

positioning and clamping components

taking manual hits and determining probe alignment

verifying probe/s configuration to specifications

selecting and activating part programs as required where machine is fitted with microprocessors

verifying and confirming correct program operation

applying correct measuring techniques

reporting out of tolerance measurements

shutting down the part program

removing and handling components

cleaning machine and site

following verbal instructions

orally reporting routine information

Required knowledge

Look for evidence that confirms knowledge of:

task-related information on job sheets or equivalent

pre-start checks

hazards and control measures associated with operating a CMM, including housekeeping

use and application of personal protective equipment

safe work practices and procedures

fixtures/clamping devices and their uses

storage location and procedures

procedures to safely remove and handle components

required cleaning tasks and the importance of cleaning the CMM

effects of contamination

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.

Probe

Solid or electronic trigger probes

Measurements

Are limited to those which can be measured directly and do not require to be constructed mathematically
