Purpose
People credited with this unit standard are able to: develop and
test a system involving rotary motion, in a prototype, for a
design project; develop and test a system involving
reciprocating motion, in a prototype, for a design project; and
develop and test a system involving oscillating motion, in a
prototype, for a design project.

Explanatory notes
1
This unit standard may be used to award credit for the achievement of learning
outcomes consistent with Technology in the New Zealand Curriculum (Learning
Media Wellington, 1995).
2
The specifications for the design projects require the solution of mechanical
problems.
3
In the process of solving the mechanical problems, learners are expected to carry out
design calculations, graphic solutions, test mock-ups, and practical applications.
4
Evidence may be gathered, over time, from more than one development and testing
activity.
Outcomes and evidence requirements
Outcome 1
Develop and test a system involving rotary motion, in a prototype, for a design project.
Evidence requirements
1.1
The principles of rotary motion are identified in relation to the project’s design.
1.2
Rotary motion system designed meets specifications for the design project.
1.3
A prototype of the system is constructed in accordance with the design.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
