Evidence Required
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. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors should ensure that candidates can: design and manufacture glass apparatus systems interpret a brief, including design requirements and cost prepare apparatus and system designs incorporate appropriate design factors relevant to use requirements of apparatus select appropriate grades of glass and components and prepare for use apply basic theoretical knowledge of chemistry and physics and make relevant design conclusions identify atypical situations and take appropriate action communicate problems to either supervisor or outside service technician record and report work results follow correct OHS and principles of GLP. |
Context of and specific resources for assessment | This unit of competency is to be assessed in the workplace or simulated workplace environment. It is strongly recommended that assessment is conducted through observation over time. The timeframe must allow for adequate assessment of operation under all normal and a range of abnormal conditions. Where this is not practical additional assessment techniques must be used. This unit of competency may be assessed with: MSL965002A Perform glass coating, grinding and finishing operations MSL965003A Construct, modify and maintain high vacuum systems. Resources may include: access to a scientific glassblowing facility, appropriate equipment, materials and procedures access to more than one workplace or simulated learning environment if the primary workplace or learning environment is unable to provide a suitable range of equipment. |
Method of assessment | The following assessment methods are suggested: inspection of examples of glasswork and workplace documentation completed by the candidate analysis of the candidate's work records over a period of time to ensure accurate and consistent work is obtained within required timelines feedback from peers and supervisors oral/written questioning. In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. Access must be provided to appropriate learning and/or assessment support when required. The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment. |
This competency in practice | Industry representatives have provided the case study below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. Manufacturing A scientific glassblower, who works for a town gas company, has been requested by the research laboratory to design and manufacture a complex gas extraction train. The equipment will be used to burn town gas under a range of conditions and analyse the exhaust gases by bubbling them through a number of gas extraction bottles. The apparatus will be used around the plant and therefore it must be portable, small and contained within a safety box in the event that there is an explosion in the apparatus. After scoping the general design with the research staff, the glassblower prepared a detailed design with particular emphasis on the size and the technical requirements associated with the need for metal electrodes in glass and metal to glass seals. They also analysed the risks of an explosive air/gas mixture developing in the apparatus and the use of hazardous chemicals in the gas bubbling/extraction bottles. The glassblower selected the glass, prepared the glassblowing tools and equipment and constructed the apparatus according to the detailed design. They carefully performed the annealing operation given the complexity of the apparatus. They then liaised with the workshop staff who were building the box to contain the apparatus. Finally, the whole system was checked under operational conditions and handed over to the research staff. |
