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 specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package
Overview of assessment requirements	A person who demonstrates competency in this unit must be able to perform milling operations. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Context of 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.
Interdependent assessment	This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with milling operations 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.
Consistency of performance	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.
Required skills	Look for evidence that confirms skills in:
	setting up jobs using appropriate equipment
	calculating and setting cutting feeds and speeds appropriate to the job
	interpreting drawings and job instructions/specifications
	milling components to specification
	visually and dimensionally checking components for conformance to specification
Required knowledge	Look for evidence that confirms knowledge of:
	safety hazards associated with milling machines
	sequence of operations to achieve the job requirements
	cutter types and tooling geometry
	consequences of varying speeds and feeds from the optimum rates calculated
	effects of different materials on cutting speeds and feeds
	conventional and climb milling techniques and their applications
	the application of each of the following: slab, gang, shell, slot, form, and slitting
	applications requiring the use of dividing heads and rotary tables when milling components
	the procedures for using dividing heads and rotary tables on milling machines
	appropriate techniques, tools and equipment to measure milled components
	use and application of personal protective equipment
	safe work practices and procedures

Required Skills and Knowledge

Range Statement

The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here. The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable
Variable	Scope
Drawings	Engineering drawings to AS 1100/1102
Tooling	Slab, gang, end, shell, slot, form, slitting cutters
Cutting parameters	Setting up machine, feed and speed calculations
Accessories	Dividing heads and rotary tables
