Hello,

I was wondering if there was a guidance by the IIA about sampling ~ something that would allow me to identify the number or selections needed for testing in an internal audit engagement.

The only guidance I found generally discusses sampling but there are no attached schedules or anything specific.

I know in public accounting we had tables that we used along with the Materiality considerations that we calculate during planning, I’m not sure how that compares in Internal Audit since we don’t really calculate materiality, or anything like that.

It seems that the practice has been to use a number like 25 for samples.

I really appreciate your input.

@isauditforme In IT audit, the methodology at my big 4 firm is 10% of the population or max of 25 depending on the type of test. For example, term user access was a 100% sample test.

F - 2/15/2014 - 85
B - 2/26/2014 - 88
R - 4/1/2014 - 83
A - 4/21/2014 - 95

Thanks for your reply Jordan 23 cc i really appreciate your input.

I'm just confused about documenting why I am using “25” as the sample size for my testing.

It is the “The magical number” in the company I work for. We don't have a detailed methodology or research behind our use of sample size like a big 4 would.

Again, thanks for sharing,
