Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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 service combustion engines. 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 servicing combustion engines 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.

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

checking items removed from the engine for serviceability and conformance to specifications

planning and sequencing operations

checking task-related information

identifying and reporting on fluids and items which have abnormal appearance

flushing engine fluids from the engine and cleaning the engine of any residual fluids

replacing engine fluids with the correct fluids to the correct levels

removing and replacing engine consumable fluids and components

checking the engine for lubricant, water and air leaks after servicing

securing wires, hoses and ducts after servicing

making minor running adjustments

obtaining test samples

undertaking calculations and numerical operations within the scope of this unit

recording and reporting service activities

Required knowledge

Look for evidence that confirms knowledge of:

common defects that can be identified from the appearance of fluids and items

the procedures for reporting items/fluids with abnormal appearance

the principles of operation of the lubrication and cooling systems

the function of filters

the purpose of a range of additives

the procedures for draining and flushing fluids from the engine including the reasons for ensuring any residual/spilt fluids are removed from the engine

the appropriate grade and type of replacement fluid

the procedures for replacing engine fluids

the correct proportions of additive to be used

the procedures for removing/replacing engine consumable fluids and components

the procedures for checking serviced engines for leaks

the methods of fastening/securing wires, hoses, ducts, etc.

the procedures for undertaking minor running adjustments

the specifications pertaining to those adjustments

the procedures for taking test samples

the procedures for reporting service activities

hazards and control measures associated with servicing combustion engines

safe work practices and procedures

Range Statement

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.

Engine consumable fluids and components

These include components and fluids that are designed to be replaced or restored as their effectiveness diminishes, or where they are wearing/failing. Typically they would include filters, coolants, lubricants, hydraulic and other fluids, additives etc, simple drive belts and coolant hoses

Running adjustments

These are limited to straightforward adjustments typical of which are belt tensions, shroud clearances, linkage adjustments, etc.
