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.

Watch construction, function and characteristics include one (1) or more of the following:

mainspring variation of motive force

gear train freedom, including:

end shakes

side shakes

backlash

escapement operation performance

oscillator amplitude, balance spring positional changes and influences

winding and setting mechanisms

Condition and faults include one (1) or more of the following:

end shakes, side shakes and clearances of operating components

oscillators balance spring condition, shock protection operation, condition and component replacement

functioning, clearances and safety action of the escapement system

mainspring and barrel assembly condition

gear train (including pivot, pinions or bearings conditions - wear and corrosion)

winding and setting components (wear and end shake freedom)

lubrication including type, application, quantity and cleanliness

Timekeeping performance includes one (1) or more of the following:

regulating system components adjustment

balance spring condition, including:

flat

concentric

beating evenly between curb pins

beat error diagnosis and adjustment

Sub-assemblies and components include one (1) or more of the following:

balance and cock assembly

escapement components

barrel and mainspring assembly

gear train

winding and setting mechanisms, including motion work and canon pinion

hand setting tension

shock-resistance system

calendar, winding system and other mechanisms

power reserve

Watch performance/rate testing includes one (1) or more of the following:

in-beat adjustment without movable stud holder

rate adjustment

amplitude evaluation of watches performance

Hand tools and equipment include one (1) or more of the following:

timing machine

staking set

jewel press

eyeglass, screwdrivers and tweezers

case opening and closing tools

Appropriate working environment includes the following:

clean bench and working area

adequate lighting and ventilation

tools and equipment are organised and in good condition

ergonomic seating

ventilation

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.
