Application
This unit of competency covers conserving heritage leadlight and stained glass by preservation, restoration or reconstruction under the principles determined by the Australia International Council on Monuments and Sites (ICOMOS) Burra Charter.
Licensing, legislative or certification requirements may apply to this unit and relevant state/territory and local government agencies should be consulted to determine any necessary certification or licensing for undertaking glass and glazing work. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work (ASCC 2007).

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 a panel, materials, equipment and specifications relevant to the conservation of heritage leadlight and stained glass panels.
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.
Range Statement
Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment. | |
Unit context includes: | WHS requirements, including legislation, building codes, material safety management systems, hazardous and dangerous goods codes, and local safe operating procedures or equivalent work is carried out in accordance with legislative obligations, environmental legislation, relevant health regulations, manual handling procedures and organisation insurance requirements work requires individuals to demonstrate discretion and apply judgement and problem solving to complex issues |
Conservation includes: | advice in the Australia ICOMOS Burra Charter as meaning all of the processes of looking after a place needed to retain cultural significance preservation, restoration, reconstruction and adaptation dependent upon specific circumstances (it commonly involves a combination of more than one of these). It also requires that the stained glass conservator respects and understands the requirements of other specialist crafts and the role of other specialist artisans |
Preservation includes: | maintaining the leadlight and stained glass panel in its existing state and of retarding deterioration |
Restoration includes: | returning the leadlight and stained glass panel to a known earlier state by removing accretions or by re-assembling existing components without the introduction of new material |
