Testing Documentation
Checklist for Internal Audits
Listed below are the items auditors
or other internal control compliance professionals should include as
part of their documentation for each control activity to ascertain
efficiency and effectiveness of the internal audit procedures, lower
the time and resource requirements for the regulatory compliance and
attestation procedures.
Some of the items below may appear intuitive; however most of them are
consistently omitted in the testing documentation we review. In the
effort of improving the efficiency of internal and external review
processes, it is recommended to consistently include the key workpaper
elements below as part of all testing documentation:
Description of inquiry
testing performed, including:
- Date
of the inquiry
- Name
and the title
of the person auditor spoke to
- Brief description of the relevant information collected
during inquiry
Examples:
- Inquired of [Name], [Title], on [Date]
- Per discussion with [Name], [Title], on [Date]
- Corroborated with [Name], [Title] and [Name], [Title] on [Date]
When available,
description of
inspection of relevant standard operating procedure or other policy
documentation, including, as appropriate:
- Effective date
and version
number
- Relevant
excerpts of the policy as it relates to the
control being tested
Example:
On [Date] inspected Company’s Password Policy dated [Date], noting the
following: XYZ.
Description of the
population & testing sample, including as
appropriate:
- Nature
of system-generated population (e.g. list of active
users generated on xx/xx/xx)
- If no system-generated population is available, explain how
an alternative population was identified
- Total
population size for the time period under review
(e.g., 01/01/10 – 12/31/10) should be documented along with a method
for selecting a representative sample
- Note that the sample selection should be representative
of
the time period under review – the selection should be made throughout
the year (see sampling guidelines below)
- If the number of samples selected does not follow the
prescribed guidance based on population, please explain the rationale
for the sample chosen
- Sample
selection rationale
(i.e., using random number generator software, judgmentally,
etc.)
- Description of the scope of the sample,
if applicable
(e.g., “A sample of XYZ users with account creation dates
during XYZ
period was selected across the following XYZ
applications: XYZ")
Example:
On [Date] obtained from [Name], [Title], a system generated listing of
user IDs created in [System Name] between [Date] and [Date] noting
[Total Number of User IDs] of users. Haphazardly selected [Number of
Selections] of [Total Number of User IDs] for testing.
The sample selection
should be
based on the frequency or number of occurrences, with suggested minimum
sample sizes as follows:
| Annually/Quarterly |
1
to 4 |
1 |
| Monthly |
5
to 12 |
2 |
| Weekly |
13
to 52 |
5 |
| Daily |
53
to 260 |
15 |
| Many
Times a Day |
Greater
than 260 |
25 |
Description of the
inspection
testing, including, as appropriate:
- Detailed steps
of testing performed, including attributes
tested for each sample
- Reference to a supplemental spreadsheet that contains
sample detail. Sample detail should include enough information for each
sample such that someone could re-perform
all of the test steps
- Documentation should show that sufficient competent audit
evidence was obtained to provide a reasonable basis for the conclusions
reached (retain
evidence!)
Description of conclusion
on the
effectiveness of each control activity tested, including as appropriate:
- Clearly document the description of relevant
issues /
findings
- Make sure conclusions are consistent with the results of
the work performed
- When a preliminary issue or finding was deemed not an
exception after further research or explanation, please document this
rationale using in sufficient detail such that someone re-performing
the test could arrive at similar conclusion
- Mitigating
controls identified and tested, if applicable.
Summarize
issues/findings:
- For issues noted during testing, refer to a
document containing a summary
of all
exception
- In the summary document, include enough
information for any exception to “stand
on its own” (i.e., one does not need to go
back to the testing workpaper to understand it)
- For issues deemed
low risk, include rationale
for
reaching such a conclusion.
