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 candidates

web service code test and deployment

cloud computing application code test and deployment

verbal or written questioning to assess candidates knowledge of

coding standards

cloud computing

review of candidates 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 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
