Elements and Performance Criteria

The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here.
The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable
Variable
Scope
Materials
Binders, hardeners, sand additives, mould coatings
Patterns
Flatback, uneven, plated patterns , multi-joint, consumable, split patterns, loose piece patterns, patterns requiring odd sides, cored moulds, drag and cope mould etc.
Moulds
Flatback, uneven jointed, multi-part moulds
Core
Full, half and segment cores
Secured
Weights, clamps, bolting
Moulding media
Green sand, shell sand, chemically bonded media etc. may be used
Pouring basin
Hand and pattern formed
Parting and stripping systems
Dry and wet
Runners
Hand and pattern formed

The evidence guide specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package
Overview of assessment requirements
A person who demonstrates competency in this unit must be able to produce jobbing moulds and cores by hand. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Context of 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.
Interdependent 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.
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.
Consistency of performance
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.
Required skills

pattern care and storage
environmental requirements
use and application of personal protective equipment
safe work practices and procedures
hazards and control measures associated with producing moulds and cores by hand (jobbing)
