This unit has linkages to a wide range of other units in various Training Packages and combined assessment and/or training would be appropriate.

ELEMENT

PERFORMANCE CRITERIA

1 Determine technical drawing requirements.

1.1 Review relevant documentation/concept information to determine technical drawing requirements.

1.2 Where appropriate, liaise with relevant colleagues to confirm and clarify technical drawing requirements.

2 Select techniques.

2.1 Identify and select appropriate materials, tools and equipment suitable for technical drawing.

2.2 Safely follow procedures to test and practise a range of technical drawing techniques.

3 Produce technical drawings.

3.1 Select the most appropriate technical drawing technique for the work to be produced.

3.2 Select the materials, tools and equipment appropriate to the technique.

3.3 Use technical drawing techniques correctly to production drawings which are consistent with concept/purpose of the drawing.

Required skills:

literacy skills sufficient to interpret material required to produce technical drawings

numeracy skills sufficient for calculations and measurements required to produce technical drawings.

Required knowledge:

physical properties and capabilities of the range of materials, tools and equipment used for technical drawing work

knowledge about technical drawing techniques and their application to a range of contexts and subject matter

technical drawing practices, their history and theory

awareness of copyright, moral rights and intellectual property issues and legislation

organisational and legislative occupational health and safety procedures in relation to technical drawing work.

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.

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

The following evidence is critical to the judgement of competence in this unit:

production of technical drawings which show a command of the selected techniques and meet the required purpose/objectives

knowledge of technical drawing techniques and their application to specific contexts.

Context of and specific resources for assessment

The assessment context must provide for:

practical demonstration of skills using required materials, tools and equipment to produce technical drawings consistent with the concept/work requirements.

Method of assessment

Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge, and might include:

direct observation of the drawing in progress

evaluation of technical drawings produced by the candidate

questioning and discussion of the candidate's intentions and work outcome

review of portfolios of evidence

third party workplace reports of performance by the candidate.

Assessment methods should closely reflect workplace demands (e.g. literacy) and the needs of particular groups (e.g. people with disabilities, and people who may have literacy or numeracy difficulties such as speakers of languages other than English, remote communities and those with interrupted schooling).

Assessment of this unit requires access to the materials, resources and equipment needed to produce technical drawings.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
