Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

OHS requirements for glaze work.
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.
References may include: | art critics, cultural theorists, philosophers and social commentators art history texts exhibitions, museums and galleries films images, objects and artworks internet journal articles own experience performances and presentations technical or medium-specific information writings. |
Intellectual property requirements may include: | copyright extent to which the work may be used form of acknowledgement or credit procedures for seeking permission to use the work of others, including systems for the administration of copyright protocols for the adaptation of work by others. |
Safety issues include: | correct lifting techniques safe disposal of waste and recycling hazards associated with glaze work: respiratory ingestion eye hazards dermatological physiological legislative requirements requirements of a safe working area safe use of tools and equipment use of personal protective equipment (PPE) to protect against such things as: clay and glaze dust lustre and thinner fumes. |

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
