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:

develop an interactive game that implements game physics

identify, evaluate and use a physics library.

Context of and specific resources for assessment

Assessment must ensure access to:

computer terminal

integrated development environment

word-processing application

the internet

physics libraries

computer hardware, software, games engines and file storage

copyright and intellectual property legislation

OHS legislation and enterprise policy

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 working executable that implements game physics

review of work samples or simulated workplace activities

review of fault-finding exercises

evaluation of reports and logbooks.

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.
