Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
produce, validate, transform, format and transport XML data
exchange data between different applications and different platforms by creating and consuming web services.
Context of and specific resources for assessment
Assessment must ensure access to:
tools in accessing and developing a data source, such as integrated development environment (IDE), text editor and web browser
specific requirements, including client and functionality requirements
web server and software that host services to deploy and test web service application
libraries to develop web service and client applications, such as SOAP libraries
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 ability to:
develop XML applications to generate a report in HTML or portable document format (PDF) file by applying certain presentation style using styling tools
develop web or stand-alone applications that access and store information in XML data format
develop and consume web service applications to solve interoperability problem by writing client code in different platform
verbal or written questioning to assess candidate’s knowledge of XML.
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.
