Elements and Performance Criteria

1. Determine job requirements
   • Job instructions and specifications are interpreted correctly.
   • Type of wood pattern required is determined through application of moulding/casting techniques and foundry processes.
   • Appropriate timber/timber composites are selected to meet specification.
2. Develop and lay out wood patterns
   • Pattern parameters are calculated to specification e.g. angles, tapers, clearances, contractions etc.
   • Pattern is laid out showing tapers, machining allowances, core prints and method of construction to specification.
   • Jigs and fixtures are developed and manufactured to aid wood pattern manufacture as required.
3. Manufacture wood patterns
   • Materials are marked out and construction is developed to meet specification.
   • Using acceptable wood pattern making techniques and procedures, and utilising appropriate hand and handheld power tools, pattern or pattern component parts are produced to size and shape and checked for conformance to specifications.
   • Using acceptable wood pattern making techniques and procedures, pattern component parts are joined or fixed as required and checked for conformance to specification.
   • Pattern is correctly marked, colour coded or tagged to specifications or standard operating procedures.

Evidence Required

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	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
Critical aspects for assessment and evidence required to demonstrate competency in this unit	This unit may be assessed on the job off the job or a combination of both Where assessment occurs off the job ie the candidate is not in productive work then 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 developing and manufacturing wood patterns or other units requiring the exercise of the skills and knowledge covered by this unit
Context of and specific resources for 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 supervisors reports project work samples and questioning Questioning should not require language literacy and numeracy skills beyond those required in this unit 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
Method of assessment	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

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.
Moulding/casting techniques	The variety of sand moulding techniques and sand mediums
Timber/timber composites	Hardwood, softwood, laminates, plywood, veneers and bonded fibreboard
Calculations	Calculations include the determination of contraction rates, as well as general engineering calculations
Joining and fixing	Glued, screwed, nailed, stapled
