GUI environment
Level
6
Credits

Purpose
People credited with this unit standard are able to: demonstrate
an understanding of a graphical user interface (GUI)
environment; write a computer program using a third
generation language (3GL) for a GUI environment; and test a
computer program written using a 3GL for a GUI environment.
The performance of all outcomes is to a standard that allows
for further learning in this area.

Explanatory notes
Open. The credit value of this unit standard is calculated
assuming a person has the prior knowledge and skills to apply
the principles of creating computer programs using a 3GL in a
text-based environment.

A program specification that is suitable for implementing using a 3GL in a GUI
environment must be provided to the person being assessed against this unit standard.
The specification should include: windows, menus, data input, validation and file update,
text, drawing, colour, controls, dialogues.
Outcomes and evidence requirements
Outcome 1
Demonstrate an understanding of a GUI environment.
Evidence requirements
1.1
Use of the GUI features is demonstrated.
Range
windows, controls, configuration, online help, inter application
communication, data integration.

1.2
A description of the GUI compares the principles of GUI with text-based
environments.
1.3
Decisions on the use of a GUI environment for given situations are justified by
describing the advantages and disadvantages of the environment.
1.4
A description of current developments in GUI environments outlines the
features of those developments.
Outcome 2
Write a computer program using a 3GL in a GUI environment.
Evidence requirements
2.1
The program code implements the program design.
2.2
The program code and data structures make efficient use of computing
resources.
Range
input and output, processor, memory.
2.3
The program structure is event-driven.
2.4
The program uses the GUI application programming interface.
2.5
The program code uses language instructions that facilitate the understanding
of the code.
2.6
The program code uses language constructs that facilitate the understanding of
the code.
2.7
Global data sharing is minimised to enable weak coupling, and modules exhibit
functional cohesion.

Outcome 3
expiring
Test a computer program written using a 3GL in a GUI environment.
Evidence requirements
3.1
Testing checks all program logic paths.
3.2
The program code is corrected to eliminate errors identified through testing.
3.3
Testing verifies that the program functions according to the design
requirements.

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.
