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, the range statement and the assessment guidelines for this training package.

Overview of assessment

A holistic approach should be taken to the assessment.

Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.

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

It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:

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.

identify and take appropriate action on problems and potential problems.

Consistent performance should be demonstrated. For example, look to see that:

the process runs consistently and smoothly

all safety procedures are always followed.

Assessment method and context

Assessment will occur on computer controlled equipment and will be undertaken in a work-like environment.

Competence in this unit may be assessed:

by direct observation, supervisor's reports, project work, samples and questioning

in a situation allowing the generation of evidence of the ability to recognise, anticipate and solve problems

by using a suitable simulation and/or a range of case studies/scenarios

through a combination of these techniques.

In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Specific resources for assessment

This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level required for this unit.

Knowledge of computer controlled machines and programming, including:

the elements of a basic NC/CNC/other program and their function in controlling the operation of computer controlled equipment

machining operations

type(s) of computer controlled equipment and their applications

machining operations controlled by program

the tool path(s) to be followed when producing a part or product

the sequence of machining operations

the reasons for selecting tool path(s) and sequence of operations

the zero point of the equipment

standard codes used in the writing of programs

applications of standard codes in programming

procedures for writing programs in standard code format

procedures for completing operation sheets

the information to be included in operation sheets

influence of polymer properties on program requirements.

Competence also includes the ability to:

plan and sequence operations

check and clarify task related information.

Language, literacy and numeracy requirements

This unit requires the ability to read, interpret and follow information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

Writing is required to the level of completing workplace forms and operations sheets.

Mathematical techniques are required, eg in calculating coordinates of all relevant points on the part or product to be produced.

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. Add any 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.

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Context

This competency applies to all work environments and sectors within the industry. It requires an understanding of the operation of all relevant equipment and processes but does not necessarily require them to be used personally.

Procedures

All operations are performed in accordance with procedures.

Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.

Tools and equipment

This competency includes use of equipment and tools such as:

computer controlled machines

desktop computers.

Hazards

Typical hazards include machine operations hazards (when trialling programs).

Problems

'Anticipate and solve problems' means resolve a wide range of routine and non routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/s recorded in the procedures.

Typical problems may include:

machine malfunction

damage to machine/tools

machining errors.

Appropriate action for problems outside of area of responsibility may be reporting to

an appropriate person.

Appropriate action for solving problems within area of responsibility includes asking

questions and seeking assistance from appropriate person/sources

Variables

Key variables to be monitored include:

speed

output rate

product integrity and general conformance to specifications.
