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 must be satisfied that the candidate can competently and consistently:

interpret and apply team requirements, controlling body and category rules and supplementary regulations

apply safety requirements, including the isolation of equipment and the use of personal protective equipment

follow task instructions, operating procedures and inspection processes to:

minimise the risk of injury to self or others

prevent damage to competition vehicle or equipment

achieve required outcomes within team time and quality standards

correctly analyse, repair and conduct post-repair checks on a minimum of three (3) performance carburetted system faults, involving:

rough running, under/over fuelling, misfiring, poor performance, contamination or leaks, with:

at least one fault having a possible combination of causes involved in the sub-systems (e.g. fuel cells, pumps, pressure and/or flow regulation, management/control system and injection)

the scope of the faults necessitates the use of a range of testing equipment

work effectively with others.

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or a simulated environment that reflects as far as possible the actual working environment.

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with relevant regulatory requirements, including specified Australian standards.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

The following resources should be made available:

access to competition vehicles carburetted systems and associated test instruments

material and equipment

information on work specifications

team requirements

organisational procedures

safety procedures, regulations and quality standards.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of Required Skills and Knowledge.

Assessment methods must be by direct observation of tasks and include questioning on Required Skills and Knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.

Guidance information for assessment

Assessment processes and techniques must be culturally sensitive and appropriate to the language and literacy capacity of the candidate and the work being performed.

Required skills

Required skills include:

technical skills to the level required to use workplace technology related to carburetted fuel systems, including tooling equipment, calculators and measuring devices

communication skills to the level required to communicate ideas and information to enable confirmation of work requirements, coordination of work with technical supervisors, other technicians and workers, and reporting of work outcomes and problems

literacy skills to the level required to collect, organise and understand information related to the analysis and repair of carburetted fuel, including technical, regulatory, environmental and safety requirements

numeracy skills to the level required to use mathematical ideas and techniques to correctly interpret test results in order to determine required action for the maintenance of carburetted fuel systems

problem-solving skills to the level required to use pre-checking and inspection techniques to anticipate maintenance and repair problems, avoid reworking and avoid wastage

team skills to the level required to work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity

planning skills to the level required to plan and organise activities, including the preparation and layout of the work area and obtaining equipment and material, to avoid backtracking, workflow interruptions or wastage

Required knowledge

Required knowledge includes:

types, function, operations and limitations of carburetted fuel systems and components

properties of fuels used in the motorsport industry, including compatibility with carburetted fuel systems components

carburetted fuel systems layouts

diagnosis and testing procedures, and test instrument application

symptom and cause differentiation

repair and/or performance improvement strategies

removal, replacement and repair, adjustment and post-repair check procedures

diagnosis theory, including concept, design and planning

record keeping procedures, including procedures for reporting equipment faults and component defects

team guidelines regarding acceptable quality and tolerance levels

equipment safety requirements

OHS policies and procedures

applicable commonwealth, state or territory legislation, regulations, standards and codes of practice, including OHS, personal safety and environment, relevant to systems
