Unit of competency details

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the 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 produce basic engineering drawings to AS 1100.101–1992 Technical drawing – General principles.

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.

Specifically the candidate must be able to:

• work within typical site/teamwork structures and methods
• apply worksite communication procedures
• comply with organisational policies and procedures, including quality requirements
• participate in work meetings
• comply with quality requirements
• use industry terminology
• apply appropriate safety procedures
• produce drawings in orthogonal and isometric projection to AS 1100.101–1992 Technical drawing – General principles
• produce drawings in third angle projection, including auxiliary views, sections and assemblies
• include all details, symbols and notation.

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 producing basic engineering graphics, 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.

Specifications 

Specifications may be obtained from:

• design information
• customer
• ideas
• concepts/expectations/requirements
• sketches
• preliminary layouts

Drawings 

Drawings may include:

• plans
• diagrams
• charts

Consultation 

Consultation may include

• reference to appropriate personnel, including technical supervisors, manufacturers, suppliers, contractors and customers

Engineering parts list 

Engineering parts list may include:

• part name
• description of part
• material specification or part number
• quantities
• other details, as required

Issued drawings 

Issued drawings may include:

• hard copy
• photographic, slide or transparency form, including presentation as a single drawing and/or with other drawings
• support documentation as a package
