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: create dynamic web pages from a client requirement using server-side scripting to retrieve information from a web-hosted database create scripts for the quick upload of data to web-hosted databases create server-side scripts for inserting, updating and deleting data from a web server database create server-side scripts to encode passwords create server-side scripts to upload and retrieve images create server-side scripts to manage sessions and secure login. |
Context of and specific resources for assessment | Assessment must ensure access to: client requirements functionality and scope requirements security policy database server internet and server access software development environment web browsers appropriate learning and assessment support when required. Where applicable, physical resources should include equipment modified 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 of candidate regarding server-side scripts evaluation of a web application using a project-based scenario to demonstrate level of competency. |
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.
Web document may include: | previously created and new HTML documents; saved email files with or without attachments saved HTML documents. |
Language may include: | active server pages (ASP) .NET Perl hypertext preprocessor (PHP) Ruby On Rails. |
External data source may include: | Microsoft Structured Query Language (MS SQL) database MySQL database Oracle database Postgre database eXtensible markup language (XML). |
Documentation may follow: | audit trails International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) standards naming standards project-management templates report-writing protocols version control. |
