PURPOSE OF THE UNIT STANDARD 
This unit standard is intended:
  • To provide a Proficient knowledge of the areas covered.
  • For those operating the workplace in the area of systems development.

    People credited with this unit standard are able to:
  • Analyse problem situations to plan an object oriented programming(OOP) implementation.
  • Demonstrate an understanding of inheritance in object oriented programming (OOP).
  • Demonstrate an understanding of polymorphism in object oriented programming (OOP).
  • Use abstract classes to optimise re-usability.
  • Use basic design patterns to optimise re-usability.
    The performance of all elements is to a standard that allows for further learning in this area. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit value of this unit is based on a person having the prior knowledge and skills to:

    Please note that the relevant Education and Training Quality Authoriy (ETQA) must accredit providers before they can offer programs of education and training assessed against unit standards.

    Moderation Process:

    Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures. 

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    1. Performance of all elements is to be carried out in accordance with organisation standards and procedures, unless otherwise stated. Organisation standards and procedures may cover: quality assurance, documentation, security, communication, health and safety, and personal behaviour. An example of the standards expected is the standards found in ISO 9000 Certified Organisations.
