- future List A classifications made by ICC or its member countries should be consistent with
- each other
- past decisions
- the definition of List A as written by the ACS and now being adopted by ICC
- the ACS should continue to maintain the register of matches it believes should be List A with Governing Bodies advising by exception should they wish to add or remove any matches from this list.

- A detailed definition of List A that explains many of the List A status decisions previously taken by the ACS and the criteria to be used by ACS in its future List A classifications.
- Registers of
In 2008 ICC incorporated List A Twenty20 into the Classification of Cricket document as a separate sub-category under the same principles.
