Efficient Audit Sampling

– Valid audit results through methodical and professional audit work –


The economic principles have already arrived in internal auditing. The internal audit function acts in an environment of increasing regulation not only for banks but also for many other businesses. New tasks add to the pressure. Cost cutting also doesn’t stop at the doors of the internal audit function so an efficient approach to audit performance is without alternative. This includes perceivable added value to the organisation. However, the main focus is on the efficient use of the remaining scarce resources. This situation demands for effectiveness and efficiency in all phases of audit work.

One of the main questions in auditing is the effectiveness of controls. Especially when resources are sparse and not all transaction may be tested, sampling is the method of choice to prove adequately if a control is working or not. To sample authoritatively auditors have to be knowledgable about the methods used. The Audit Research Center provides an overview of valid sampling methods that are in line with international standards of the IIA and the ISA.

Audit practitioners often think that sampling is complicated and time consuming. In this training the participants will see that the contrary is true if sampling is done right. Sampling safes time and increases the quality of audit results.

The training focuses on statistical methods. However, all kinds of sampling will be touched. Non-statistical sampling and when to do it instead of statistical sampling is also an important topic of good audit work. As is the comprehensive documentation of the audit procedure according to international standards and the expectations of the external auditors.

After this training the participants are able to perform efficient and effective statistical and non-statistical audit sampling. They know about the relevant methods and when to use them. The content of this training is in line with all relevant international standards, specifically Standard 2320 and the associated Implementation Guidance (PA 2320-2).
