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 a range of jobbing moulds and cores by hand. 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 situations and contexts. Critical aspects of assessment and evidence include:
following all safety procedures for working safely in a typical working foundry environment
knowledge of the casting process including the role of patterns, sands, moulds and cores, and the importance of correct methoding
matching of specifications, sketches and drawings to mould and core requirements for a range of patterns, metals and sands
planning skills are evident in sequence of work, selection and layout of materials, and construction of moulds and cores
appropriately identifying, assembling and determining patterns as fit for purpose
ensuring core positioning is in accordance with job specifications
placing methoding components in accordance with job specifications
selecting moulding equipment and media to match a range of job requirements
making moulds, cores and pouring basins for a range of jobs and metals efficiently and to meet all safety requirements with minimum waste of materials
disposing of used sand and debris according to standard operating procedures and regulations.
Context of and specific resources for assessment
This unit has been developed to support training in and recognition of trade level jobbing moulding skills as applied to a jobbing moulding environment.
Assessment resources include a furnace to supply adequate molten metal for testing of moulds and cores, sand and other materials to enable enough sufficient moulds and cores to be produced and all normal foundry safety and personal protective equipment.
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
The emphasis for assessment should be on jobbing ability, that is, the ability to produce moulds and cores for a variety of job specifications involving different metals, sands and patterns.
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 producing jobbing moulds and cores by hand 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.
