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: design, build, test and deploy a web service to specification that can be accessed and used from a separate web application design, build, test and deploy a cloud computing application to specification that can be accessed from a variety of portals document the completed development. |
Context of and specific resources for assessment | Assessment must ensure access to: specific requirements, including client and functionality requirements IDE for the determined language database server with tools to access data source and develop queries web server for determined environment internet and web browser 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: web service code, test and deployment cloud computing application code, test and deployment verbal or written questioning to assess candidate’s knowledge of: web services coding standards cloud computing review of candidate’s completed documentation. |
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.
Gather requirements may include: | interviews observation questionnaires requirements already documented reviewing existing documentation. |
Development environment may include: | AJAX Eclipse incorporating Java HTML, XHTML and CSS JavaScript JSP Microsoft Visual Studio incorporating ASP, C#, Visual Basic PHP Python. |
Architecture may include: | capacity considerations network topology operating system public or private network scalability security model web server, such as IIS or Apache. |
Framework may include: | .NET Apache Axis Apache CXF Halycon Hessain Web Services Interoperability Technology WSO2 WSF/PHP. |
Protocols may include: | representational state transfer (REST) simple object access protocol (SOAP) universal description, discovery and integration (UDDI) web processing service (WPS) web services description language (WSDL). |
