Evidence Required

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

The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria required skills and knowledge and the range statement of this unit and include evidence of the following

knowledge of the requirements procedures and instructions for conducting scraper operations

implementation of requirements procedures and techniques for the safe effective and efficient completion of scraper operations including

a minimum of two different soil types and

are to include the mandatory tasks of stripping of materials to specified depth the cutting and filling of materials to line and level stockpiling and spreading

where push pull scrapers are used tasks are to include coupling operating in tandem and disengagement

working with others to undertake and complete scraper operations that meet all of the required outcomes

consistent timely completion of scraper operations that safely effectively and efficiently meet the required outcomes

Context of and specific resources for assessment

This unit must be assessed in the context of the work environment Where personal safety or environmental damage are limiting factors assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance including task skills task management skills contingency management skills and job role environment skills

The assessment environment should not disadvantage the participant For example language literacy and numeracy demands of assessment should not be greater than those required on the job

Customisation of assessment and delivery environment to sensitively accommodate cultural diversity

Aboriginal people and other people from a non English speaking background may have second language issues

Assessment of this competency requires typical resources normally used in the work environment Selection and use of resources for particular worksites may differ due to site circumstances

Where applicable physical resources should include equipment modified for people with disabilities

Access must be provided to appropriate learning andor assessment support when required

Method of assessment

This unit may be assessed in a holistic way with other units of competency The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods

written andor oral assessment of the candidates required knowledge

observed documented andor first hand testimonial evidence of the candidates

implementation of appropriate requirement procedures and techniques for the safe effective and efficient achievement of required outcomes including

a minimum of two different soil types and

are to include the mandatory tasks of stripping of materials to specified depth the cutting and filling of materials to line and level stockpiling and spreading

where push pull scrapers are used tasks are to include coupling operating in tandem and disengagement

consistently achieving the required outcomes

first hand testimonial evidence of the candidates

working with others to undertake and complete scraper operations

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.

Relevant compliance documentation

may include:

legislative, organisation and site requirements and procedures

manufacturer's guidelines and specifications

Australian standards

codes of practice

Employment and workplace relations legislation

Equal Employment Opportunity and Disability Discrimination

Scrapers may include:

elevating scrapers, which are self-propelled articulating wheeled machine with a prime mover and sliding floor bowl configuration

the bowl houses an elevator system designed to assist in loading and unloading the bowl

the elevator system is normally hydraulically driven from the main engine; however, the elevator system may be driven by a separate power source

open bowl scrapers, which are self propelled articulating wheeled machine with a prime mover and sliding floor bowl configuration

these may be of a standard open bowl, tandem powered or push-pull configuration

the standard open bowl scraper normally requires the assistance of a push dozer when loading

standard open bowl and tandem powered scrapers may be fitted with an auger attachment in the bowl, to provide self-loading capability

Scraper tasks are to include:

the stripping of materials to specified depth, the cutting and filling of materials to line and level, stockpiling and spreading

where push pull scrapers are used, tasks are to include coupling, operating in tandem and disengagement

Scraper tasks may include:

stripping/spreading topsoil, granular materials, cutting drains, cutting battens, cutting/boxing, backfilling and rough grading
