Issue Date: May 2024


This unit of competency covers the skills and knowledge required to plan and develop a two-dimensional pattern from which three-dimensional products or moulds can be made. Two-dimensional patterns are typically used in the fabrication, thermoforming, composites and rubber lining sectors.

This unit of competency applies to experienced operators who are required to interpret drawings and specifications, plot the dimensions and ‘develop’ solid objects into two-dimensional patterns, check and complete the pattern and solve problems within area of responsibility.

This unit of competency applies to an experienced operator demonstrating theoretical and technical knowledge and well developed skills in situations that require some discretion and judgement. The operator may work alone or as a member of a team or group and will work in liaison with other shift team members, team leader and supervisor, as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.

Where the assessee does not currently possess evidence of competency in MEM09002B Interpret technical drawing, it may be co-assessed with this unit.

The collection of performance evidence is best done from a report and/or folio of evidence drawn from:

a single project which provides sufficient evidence of the requirements of all the elements and performance criteria

multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.

A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.

Assessment should use a real project in an operational workplace. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur using a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:

walk-throughs

pilot plant operation

industry-based case studies/scenarios

‘what ifs’.

Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.

The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.

Foundation skills are integral to competent performance of the unit and should not be assessed separately.

Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.

In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.

Technical competence can be demonstrated through one or more of:

relevant VET or other qualification/Statement of Attainment

appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions

appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions

Currency can be demonstrated through one or more of:

being currently employed undertaking the type of work being assessed

being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures

having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment

conducting on the job training/assessments of the type of work being assessed

being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
