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 undertake activities from proposal to implementation stage for a data warehouse model that reflects current and future business requirements and the business knowledge management strategy
Context of and specific resources for assessment	Assessment must ensure access to data in a DBMS datawarehousing tool 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 written report outlining costbenefit analysis of a data warehouse implementation for a defined organisation user guide for usage of an implemented data warehouse technical documentation for an implementation of a data warehouse questioning to determine knowledge of relationship between databases and data warehouses project to implement a data warehouse
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
