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 assemble and test complex engineering components and mechanical assemblies. 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 precision assembly 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

Look for evidence that confirms skills in:

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

preparing a sequential assembly plan

selecting and sourcing appropriate tools, components and sub-assemblies

using tools appropriately

following job instructions

identifying faulty components

following oral instruction

entering routine and familiar information onto proformas and standard workplace forms

Required knowledge

Look for evidence that confirms knowledge of:

fitting requirements

uses of relevant tools and equipment

sequence in which the tasks are to be performed

sources of the component/sub-assemblies

required action for tests and checks

required action for non-conformance

damage to components and/or assemblies through the use of inappropriate handling and/or unsafe storage procedures

relevant record keeping requirements

use and application of personal protective equipment

safe work practices and procedures

hazards and control measures associated with precision assembly

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.

Components/sub-assemblies

Includes parts that make up the sub-assembly and components

Technique

Assembly methods and correct use of hand tools

Records/inputs

Production schedules, job sheets, checklists

Tested

Tests and checks to specification of assembled product

Adjustments

Clearances, mesh, tension, level, alignment etc. using predetermined standards of quality and safety
