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 configure a database startup ensure data integrity monitor data storage requirements for database update data update database access
Context of and specific resources for assessment	Assessment must ensure access to live database preferably on a LAN on which there is a server that offers login functionality 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 review of candidates database verbal or written questioning to assess candidates knowledge of database security database space requirements function of indexes and data dictionaries monitoring of database access evaluation of candidates database documentation detailing startup and operation irregularities network server logs of security breaches maintenance tasks performed by whom and when
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
