Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

prepare and interpret blueprints, drawings, sketches, designs and customer requirements

apply theoretical concepts and practical principles to construct, modify and maintain vacuum systems

evaluate and make recommendations for modifications to vacuum systems

modify high vacuum systems to meet new requirements

use appropriate procedures to monitor and maintain high vacuum systems

use advanced bench/hand glasswork techniques and equipment to fabricate glass apparatus

follow enterprise procedures to document and communicate work details.

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:

MSL965001A Design and manufacture glass apparatus and glass systems

MSL965002A Perform glass coating, grinding and finishing operations.

Resources may include:

access to a scientific glassblowing facility, appropriate equipment, materials and procedures which will allow for appropriate and realistic simulation

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.

Education

A major research organisation has requested assistance with the design and construction of an ultra high vacuum line to work in conjunction with a recently purchased mass spectrometer. The scientific glassblower identifies the location of the backing pump, vapour jet pump, turbo-molecular pump and getter pumps. After finalising the design, they manufacture the main components in the glassblowing workshop. They then take the portable glassblowing station, including hand torch, gas supplies and hand tools to the research laboratory and proceed to link these components with various sizes of glass tubing and transition glass/metal vacuum flanges. Having completed the vacuum system, the glassblower assists with checking all joints and seals under vacuum conditions and undertakes any repairs and modifications. Finally they dispose of all waste appropriately and return the equipment to the workshop.
