Overview

Audit and Assurance — overview

As many organisations and businesses now operate in the global marketplace, the role of audit and assurance is becoming increasingly important as it is seen as providing a measure of confidence in the rapidly changing accounting and business environment. This is as a result of their impact upon the overall success of a business and achievement of strategic objectives. Audit and assurance services have also come under increased scrutiny from the profession following high-profile corporate failures.

This unit aims to develop a wider understanding of the principles and concepts, including the legal and professional rules of audit and assurance services. The unit will provide students with an awareness of the audit process from planning and risk assessment to the final completion and production of the audit report. The unit also aims to provide a practical perspective on audit and assurance, with an emphasis on the application of audit and assurance techniques to current systems. Students will be equipped with the skills required to undertake an audit under supervision and will gain an understanding of relevant regulatory frameworks and ethical requirements.

Students will explore issues such as independence as well as the audit process, from the initial planning process, including risk assessments and gathering evidence, through to completion and reporting findings. The unit places an emphasis upon the application of techniques to current situations and as such, offers a practical as well as a theoretical perspective. Throughout the unit, the concept of professional scepticism is explored and challenged.

Exam Tips

How to pass Audit and Assurance

Expert tips from Learnsignal's AAT tutors to help you prepare effectively.

Know the audit risk model

Inherent risk × control risk × detection risk — it underpins most scenarios in this exam. Learn how each component responds when circumstances change.

Internal controls and weaknesses

A large chunk of marks comes from identifying weaknesses in a described system and recommending controls. Practise the format: weakness, implication, recommendation.

Audit planning and risk assessment

You'll be asked to plan an audit — materiality, sampling, risk of material misstatement. Know the ISAs at principle level (not technical citation).

Audit evidence — types and quality

Inspection, observation, inquiry, confirmation, recalculation, reperformance, analytical procedures. Know when each is appropriate and what 'sufficient appropriate evidence' means.

Audit reporting and modifications

Clean opinion, qualified, adverse, disclaimer, and emphasis of matter. Know the decision tree — when each is appropriate and why.

Ethics and independence throughout

Audit ethics is embedded in every scenario. Be ready to spot threats to independence (self-review, self-interest, familiarity, advocacy, intimidation) and propose safeguards.
