Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements
Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures
Avoid backtracking, work flow interruptions or wastage
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
Evidence of Knowledge
Qualities and characteristics of glass, including hazards and handling requirements
Correct identification and use of glass cutting equipment, their functions and procedures for use
The set-up and operation of glass cutting equipment, including procedures for reporting product defects or equipment faults
Workplace safety system requirements related to glass cutting
Work flow requirements in relation to glass cutting
Assessment Conditions
Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to glass sheet/product, cutting equipment, such as hand glass cutter, circle cutter and speed cutter and a table.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. Detail on appropriate performance levels for each furnishing unit of competency in reading, writing, oral communication and numeracy utilising the Australian Core Skills Framework (ACSF) are provided in the Furnishing Training Package Implementation Guide.
