Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
read legacy language
identify and isolate the required change
implement the change via the chosen technique.
Context of and specific resources for assessment
Assessment must ensure access to:
documents detailing organisational standards for software development
existing legacy code
appropriate compilers
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:
evaluation of candidate’s completed change in legacy code
review of candidate’s documentation that reflects modification in legacy programs
verbal or written questioning to determine candidate’s knowledge of:
key design alternatives
change-management process.
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.
