IFATCA Policy is:

ATFM staff not performing clerical or administrative functions, so called ATFM controllers, shall be qualified controllers with recent experience on control duties on entry to ATFM services.

The responsibility for aircraft in flight remains solely with ATC and any subsequent ATFM involvement shall be at the request of ATC only.

An ATFM controller shall hold an ATFM rating. Such a rating shall require the ATFM controller to demonstrate a comprehensive knowledge, skill and experience of all relevant ATC procedures and ATFM duties.

ATFM controllers should be obliged to familiarise themselves with major changes in ATC procedures and maintain their acquaintance with problem areas with relation to ATFM within their region.
