The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Read and interpret a work/job specification

Identify and interpret heritage legislation as it applies to lead light and stained glass panels

Identify historical lead light and stained glass panel construction methods

Assess and make decisions on conservation methods

Identify faults and problems with lead light and stained glass panels, and their remedial methods

Conserve heritage leadlight and stain glass panels in accordance with industry best practice

Comply with legislation, regulations, standards, codes of practice and established safe practices and procedures for the assessment of conservation requirements of lead light and stained glass panels

Communicate effectively and work safely with others in the work area

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context

Assessment is to comply with relevant regulatory or Australian Standards requirements

The following resources should be made available:

workplace location or simulated workplace

materials and equipment relevant to the conservation of heritage lead light and stained glass panels

specifications and work instructions

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency

heritage requirements specific to lead light and stained glass

established communication channels and protocols

problem identification and resolution

storage systems and labelling

procedures for the recording, reporting and maintenance of workplace records and information

appropriate mathematical procedures for estimation and measurement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

OHS requirements

are to be in accordance with Commonwealth, State or Territory legislation and regulations, organisational safety policies and procedures. Requirements may include but not be limited to the use of personal protective equipment and clothing, fire fighting equipment, First Aid equipment, hazard and risk control and elimination of hazardous materials and substances, manual handling including lifting and carrying.

Legislative requirements

are to be in accordance with applicable legislation from all levels of government that affect organisational operation. Requirements may include but not be limited to award and enterprise agreements, industrial relations, Australian Standards, confidentiality and privacy, OHS, the environment, equal opportunity, anti-discrimination, relevant industry codes of practice, duty of care and heritage.

Organisational requirements

may include but not be limited to legal, organisational and site guidelines, policies and procedures relating to own role and responsibility, quality assurance, procedural manuals, quality and continuous improvement processes and standards, OHS, emergency and evacuation, ethical standards, recording and reporting, access and equity principles and practices, equipment use, maintenance and storage, environmental management (waste disposal, recycling and re-use guidelines)

Conservation

Conservation as defined in the Australia ICOMOS Burra Charter as meaning all of the processes of looking after a place needed to retain cultural significance. It includes maintenance and may include 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 is the process of maintaining the lead light and stained glass panel in its existing state and of retarding deterioration.

Restoration means returning the lead light and stained glass panel to a known earlier state by removing accretions or by reassembling existing components without the introduction of new material.

Reconstruction means returning the lead light and stained glass panel to a known earlier state and is distinguished by the introduction of new materials.

Appropriate personnel

may include but not be limited to clients, architects, engineers construction supervisors, members of heritage committees, government agencies other specialist artisans, such as stonemasons
