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 | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: specify and model abstract data types specify the interface between classes and objects document the result. |
Context of and specific resources for assessment | Assessment must ensure access to: business, system and user requirement unified modelling language (UML) modelling tool appropriate learning and assessment support when required modified equipment for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct observation of identifying classes, objects and abstract data types and preparing class, object, module and process diagrams verbal or written questioning to assess knowledge of roles and responsibilities of classes review of documented model. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Documentation may follow: | audit trails client training International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), and Australian Standards (AS) standards maintaining equipment inventory naming standards project-management templates and report writing satisfaction reports version control. |
Standards may include: | ISO, IEC and AS standards organisational standards project standards. |
Requirements may refer to: | business network people in the organisation system. |
Specifications may include: | current system functionality technical requirements user-problem statement. |
Appropriate person may include: | authorised business representative client supervisor. |
