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

create error logging framework topersist error logs debug and trace an application and plan a performancemonitoring strategy

create error logging framework topersist error logs, debug and trace an application, and plan a performance-monitoring strategy

use debugging techniques and tools and profiling tools and analyse performance issues

Context of and specific resources for assessment

Assessment must ensure access to

client and server system

sufficient privileges to access and use performance monitoring tools in client and server systems

debugging tools

specific tools and licences depending on particular platform

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 or verbal questioning of debugging diagnostics and monitoring strategy

evaluation of candidates logging framework and custom event log for an application

direct observation of candidate using an integrated development environment IDE for code development and debugging and the monitoring applications

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
