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 mark off/out structural fabrications and shapes. 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 marking off/out structural fabrications and shapes 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 | Look for evidence that confirms skills in: |
reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents |
undertaking numerical operations, geometry and calculations/formulae within the scope of this unit |
planning and sequencing operations |
using techniques and equipment required for marking off/out and developing patterns |
checking for conformance to specifications |
establishing and marking datum points |
developing patterns according to specification |
determining fabrication and assembly allowances and transferring to the pattern |
where applicable, applying the requirements of the codes/standards during the geometric development/marking off/out process |
determining material and component quantities from drawings and job specifications |
minimising material wastage |
Required knowledge | Look for evidence that confirms knowledge of: |
procedures for marking off/out and pattern development |
the tools and equipment to be used in the preparation of the marking off/out |
the datum points |
materials that can be used for the preparation of templates and their application |
the manufacturing allowances that have to be considered when developing patterns |
template labelling and identification procedures |
storage requirements of templates |
the appropriate method(s) of development/marking off/out of a range of given objects |
the appropriate fabrication and assembly allowances |
the effects of material type and thickness on fabrication and assembly allowances |
the sources of data on fabrication and assembly allowances |
all relevant standards and codes and the meaning of symbols used |
the requirements of the codes/standards applicable to the work to be done |
the material(s) from which the component/assembly is to be manufactured |
the benefits of minimising material wastage |
any applicable industry standards, national/Australian standards, NOHSC guides, State/Territory regulatory codes of practice/standards |
safe work practices and procedures |
relevant hazards and control measures related to the competency |
