Evidence Required

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

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 candidates completed change in legacy code

review of candidates documentation that reflects modification in legacy programs

verbal or written questioning to determine candidates knowledge of

key design alternatives

changemanagement 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 nonEnglish speaking background may need additional support

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge
