2 Operators of water supply facilities, regulators, educators and local officials, jointly prepared the objectives and exam questions for this subclass. How to Use This Study Guide with References In preparation for the exam you should: 1. Read all the objectives and write down the answers to the objectives that readily come to mind. 2. Use the resources at the end of the Study Guide to look up those answers you are not sure of. 3. Write down the answers found in the resources to those objectives you could not answer from memory. 4. Review all answered objectives until you can answer each from memory. It is advisable that the operator take classroom or online training in this process before attemptingthe certification exam.

3 Choosing a Test Date Before you choose a test date, consider the training opportunities available in your area.
