Probe | Why does the sample size remain at 10, irrespective of the population size on the controls testing worksheet (90.30)?

Published:  19/08/2016
Why does the sample size remain at 10, irrespective of the population size on the controls testing worksheet (90.30)? 

  Answer:

The controls testing worksheet calculates the sample size with two inputs:
  1. The Probe Firm Settings indicates what the minimum sample size must be. In terms of the IFAC guide for small entity audits, the default is 10. The firm can change that in the Probe Firm Settings if they want to.
  2. Your sample size depends on the assurance that you require from this test. If you are constantly getting a sample size of 10, you have probably selected to get medium assurance from this test. If you want to get High assurance, this sample size will increase to 30.
