Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Appropriate techniques and procedures include:

clearances for safe approach as mandated by statutory authorities

Electrical isolation includes:

isolating supply for safe disconnection of all electrical power to equipment supply circuit with switch circuit breaker or fuses on circuits/equipment at voltage levels above 1000 volts a.c. and 1500 volts d.c.

Test equipment and tools include, in accordance with voltage and fault limiting requirements, one (1) or more of the following:

appropriate proving dead meters

high potential testers

voltmeters

Signage includes one (1) or more of the following:

tags

access permit holders

restricted access signs

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
