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:

observe safety procedures and requirements

communicate effectively with others involved in or affected by the work

select overhaul methods and techniques appropriate to the circumstances

complete preparatory activity in a systematic manner

dismantle, evaluate, assemble, adjust, measure and test engines and components in accordance with workplace requirements and manufacturer/component supplier requirements

complete overhaul of a range of engines and associated components within workplace guidelines and timeframes

present repaired equipment to customer in compliance with workplace requirements

complete workplace records.

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:

a range of outdoor power equipment engines and components

materials relevant to overhauling engines

equipment, hand and power tooling appropriate to overhauling of outdoor power equipment engines

specifications and work instructions.

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 and tools, including specialist tooling, measuring equipment and computerised technology related to overhauling outdoor power equipment engines

communication skills to the level required to confirm work requirements and specifications, to communicate effectively regarding work requirements with other workers and customers, to report work outcomes and problems, and to relate to people from a range of social, cultural and ethnic backgrounds and of varying physical and mental abilities

literacy skills to the level required to research, interpret and apply manufacturer/component supplier information, procedures and specifications

numeracy skills to the level required to correctly calculate time, assess tolerances, apply accurate measurements, calculate material requirements and establish quality checks

problem-solving skills to the level required to plan and organise activities, to establish safe and effective work processes which anticipate and/or resolve problems and downtime, and to interpret test results and develop creative solutions

team skills to the level required to work effectively and cooperatively with others to optimise workflow and productivity

Required knowledge

Required knowledge includes:

construction and operating principles of 2- and 4-stroke spark ignition engines and 4-stroke compression ignition engines
