Application
This unit of competency covers constructing and repairing leadlight panels and may involve restoration and conservation of historically important stained glass and leadlighting works. It includes measuring, design and selection of materials and tools, and disassembly/assembly, weatherproofing and polishing of leadlight panels.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

5 | Complete work | 5.1 | Leadlight panel is inspected for quality of work and repaired or reconstructed, as required, in accordance with workplace procedures |
5.2 | Material which can be re-used is collected and stored | ||
5.3 | Waste and scrap material are removed for disposal or recycling, as required | ||
5.4 | Work area is cleaned and rubbish disposed of, as appropriate | ||
5.5 | Equipment is cleaned and stored according to workplace requirements | ||
5.6 | Workplace documentation is completed in accordance with workplace procedures | ||
Evidence of Performance
Interpret work order and locate and apply relevant information
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Identify materials used in the work process
Follow work instructions, operating procedures and inspection processes to:
minimise the risk of injury to self or others
prevent damage to goods, equipment and products
maintain required production output and product quality
Interpret work order/job instruction to identify requirements and plan the process to construct/repair leadlight panels
Select and use appropriate materials and processes for the panel being constructed/repaired optimising glass sizes for economical cutting and assembling of required materials
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
End use of leadlight panels and required safety, quality and structural standards
Characteristics, including hazards and workplace safety system requirements, associated with the materials used in leadlight panel construction
Operation of tools and equipment used in constructing/repairing leadlight panels
Research techniques to establish the historical importance of stained glass and leadlighting works
Processes and procedures involved in the construction/repair process of leadlight panels, including historically important works
Impact of design features of the leadlight panel on purpose, materials and construction
Relevant Australian Standards
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 leadlight panels for repair or plans for new panels, glass, leadlighting materials, personal protective equipment and work instructions.
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.
