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 | A person who demonstrates competency in this unit must be able to manually finish/polish materials. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with manually finishing/polishing materials or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

Assessment Tasks
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.
Required skills |
Look for evidence that confirms skills in: reading and following information on standard operating procedures checking and clarifying task-related information selecting appropriate polishing/finishing method to suit work requirements fitting and adjusting endless belts on linishing machines fitting and dressing grinding wheels and mops on pedestal grinders installing and setting up polishing mops in polishing machines producing surface finishes to specification identifying surface imperfections assessing processing hazards |
Required knowledge |
Look for evidence that confirms knowledge of: typical surface finish specifications within the scope of this unit procedures, tools and techniques for fitting and adjusting endless belts on linishing machines procedures, tools and techniques required to fit and dress grinding wheels and mops procedures tools and techniques for installing and setting up polishing mops characteristics of common metals, alloys and non-metals appropriate polishing media to be used in finishing/polishing for different types of materials effect of different types and grades of polishing media on the surface finish finishing and polishing methods/techniques reasons for selecting a specific method/technique common surface imperfections/defects surface imperfections/defects that can be removed/repaired by manual finishing/polishing procedures procedures for handling components with surface imperfections/defects that cannot be removed/repaired methods and techniques to check for conformance to specifications hazards associated with the manual finishing/polishing process personal protective clothing and equipment safe work practices and procedures |
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. | |
Finish | Brightness, texture, roughness comparison |
Finishing/polishing equipment | Endless belt grinders; table linishers; pedestal grinders and polishers; felt wheels, fabric mops and brushes with underhand and overhand techniques; flexible drive appliances; buffing compounds; cutting compounds and abrasive belts |
Finishing/polishing media | Solid and liquid compositions containing alumina, silicon carbide, diamond dust, tripoli, calcium oxide and iron oxides |
Material | Cast iron, steel, zinc and its alloys, copper, aluminium and its alloys, bronzes, sterling silver, gold and plastics |
Common surface imperfections | Pitted surface, machining lines, scale, rust |
Hazards | Airborne dust inhalation, unsecured components |
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.
