Resource implications for assessment include:
access to customer premises or a simulated workplace environment
assessment documentation
necessary tools, specialist equipment, manuals and relevant documentation, including ODS and SGG policies and work procedures
training and assessment record books.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the Property Services Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm that competency is verified and able to be transferred to other circumstances and environments.
Guidance information for assessment
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
This unit could be assessed on its own or in combination with other units relevant to the job function.
