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 interpret and apply drawing specifications and industry standards in the production of drawings and schematics for the pneumatic and hydraulic fluid power systems.

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.

Specifically the candidate must be able to:

work within typical site/teamwork structures and methods

apply worksite communication procedures

comply with organisational policies and procedures, including quality requirements

participate in work meetings

comply with quality requirements

use industry terminology

apply appropriate safety procedures

produce schematic drawings of hydraulic and pneumatic power systems according to industry standard and client requirements.

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.

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

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with drafting 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.

Required skills

Required skills include:

literacy skills sufficient to read and interpret instructions, relevant codes of practice and specifications for drawing work

numeracy skills sufficient to interpret technical information and conduct mathematical problem solving as required in the scope of this unit

numeracy skills, including four basic functions, fractions, and simple algebra and formulae sufficient to calculate flow, volume, area, pressure and other necessary parameters relevant to a fluid power system

using and maintaining drawing equipment

applying relevant codes, standards and symbols used for hydraulic and pneumatic systems

drafting skills, including:

applying spatial principles to achieve scale and proportion

using appropriate lines and symbols

dimensioning and tolerancing

production of title block, material lists and other appropriate symbols

Required knowledge

Required knowledge includes:

general knowledge of different approaches to drawing schematics

awareness of copyright and intellectual property issues and legislation in relation to drawing
