TAF is an interactive learning experience designed to take new auditors through each stage of conducting an audit. It may be completed entirely online, or alternatively downloaded in PDF format for offline use. An exercise is presented at the conclusion of each unit of TAF to reinforce the learning objectives. There is also a final exercise at the end of the product to enable the learner to check the level of comprehension of basic auditing attained. We encourage all users to provide feedback about TAF to the CRA through the questionnaire included as part of the product. The CRA will monitor user feedback on an ongoing basis.
