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: obtain requirements develop web applications that keep track of user data between browser requests document web applications. |
Context of and specific resources for assessment | Assessment must ensure access to: appropriate learning and assessment support when required modified equipment for people with special needs development environment server access database server browsers. |
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 test candidate’s knowledge of the HTTP, session management and stateless programming evaluation of a web application that handles session management. |
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. |
Range Statement
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.
Code may include: | active server pages (ASP) active server pages. net (ASP.NET) Coldfusion Java server pages (JSP) Perl hypertext preprocessor (PHP) Ruby on Rails. |
Session management may include: | authentication shopping carts. |
