Process and manage optical appliance orders

Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills and knowledge required to use specialised optical knowledge to place, check and service orders for spectacle frames and lenses.

This unit applies to optical dispensers who work according to prescriptions provided by optometrists or ophthalmologists.

The skills in this unit must be applied in accordance with Commonwealth and State/Territory legislation, Australian/New Zealand standards and industry codes of practice.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
