Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to review the requirements produce CGI forms and scripts to meet the requirements upload scripts to a server test the script and rework until requirements is met
Context of and specific resources for assessment	Assessment must ensure access to web servers ebusiness website FTP or file transfer client software server access 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 verbal or written questioning to assess candidates knowledge of scripting language security issues surrounding CGI evaluation of candidates CGI form review of candidates CGI script
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
