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 perform basic metal spinning lathe operations. 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 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 performing basic metal spinning lathe 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.

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

reading and interpreting routine information on written job instructions, specifications and standard operating procedures. May include drawings

following oral instruction

entering routine and familiar information onto proformas and standard workplace forms

using all basic metal spinning tools

minimising damage and defects

calculating disc size and lathe speed

undertaking manual handling related to spinning products

using appropriate techniques, tools and equipment to measure materials and spinnings

Required knowledge

Look for evidence that confirms knowledge of:

sequence of spinning operation

types of spinning tools, their functions and requirements for maintaining tools

types of damage and defects e.g. tool marks, cracking, stress marks, thinning and incorrect finish

spinning lathe operation

why and how lathe speed is calculated

reasons for types of form chuck mounting

function and operation of accessories for basic spinning

methods used for each process

methods for stacking and protecting finished product

use and application of personal protective equipment

safe work practices and procedures

hazards and control measures associated with metal spinning lathe operations (basic)

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.
