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 grinding operations on a range of machines. 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 performing grinding 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 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.
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:
	reading and interpreting information on written job instructions, procedures, specifications, charts, lists, drawings and other applicable reference documents
	checking and clarifying task related information
	preparing an operational work plan
	planning and sequencing operations
	using precision measurement equipment within the scope of this unit
	setting up work using tools, techniques and equipment
	using coolant and dust extraction devices
	selecting and preparing grinding wheels and accessories appropriate to the grinding task(s)
	performing and monitoring internal/external cylindrical grinding process
	clamping/mounting work pieces
	checking for conformance to specifications
	performing numerical operations and calculations within the scope of this unit
Required knowledge	Look for evidence that confirms knowledge of:
	reasons for selecting the chosen sequence of operations
	the application of a range of holding devices/accessories
	reasons for selecting specific work holding devices, tools, techniques and equipment
	coolant selection/function
	standard grinding wheel shapes
	the range of abrasive materials used in grinding wheels
	factors impacting grinding wheel selection including grain size of abrasive particles; grade or strength of bond; and bond material
	grinding wheel dressing tools and their application
	internal/external cylindrical grinding process
	principles of effective clamping
	grinding operations/procedures
	the function of any grinding accessories
	tools, techniques and equipment for checking components for conformance to specifications
	hazards and control measures associated with grinding operations, including housekeeping
	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
Specifications	Dimensions and tolerances, geometry and tolerances, surface finish
Holding devices	Vices, clamps, magnetic chucks, face plates, collets, 3/4 jaw chuck, etc.
Wheels	Shape, grit/bond composition
Balanced	Static and dynamic balancing
Grinding machine	Surface, cylindrical and centreless machines
