Elements and Performance Criteria

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. 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.
Marking off/out
Marking off/out may include engineering components, jigs and fixtures, castings, templates, dies and tooling
Tools and equipment
Tools and equipment may include:
marking out tables
surface tables
rotary tables
dividing heads
vee blocks
cylinder squares
sine bars
vernier height gauges
protractors
straight edge and set squares
hammers
scribers
centre punch
marking medium

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 mark off/out in a general engineering situation. 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 apply the skills covered in this unit of competency in new and different workplace situations and contexts. Critical aspects of assessment and evidence include:
examination of detailed drawings for marking out requirements and specifications including materials, measurements and tolerances, manufacturing methods, standards and code requirements
correct calculation of measurements not shown on drawings
sequence of measuring and/or development is determined correctly
correctly establishing and marking datum points
measurements are accurately transferred to component, jig, fixture, casting, template, die or tooling
accurate production of templates.
Context of and specific resources for assessment
This unit has been developed to support training in and recognition of trade level competency in marking off/out general engineering items as applied to trade level fitting, machining and toolmaking work environment. Assessment should emphasise a workplace context and procedures found in the candidate's workplace.
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.
Method of assessment
Typically, persons engaged in Engineering Tradesperson - Mechanical work are required to apply their geometric development skills and techniques across a range of jobs and specifications.
A single assessment event is not appropriate. On the job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.
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
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with marking off/out general engineering items or other units requiring the exercise of the skills and knowledge covered by 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.
