watson in the discussion about noolite:
http://www.jehovahs-witness.com/12/166779/2.ashx
mentions a "grading system".
Funny that would be brought out. As a School Overseer
I was asked by my then PO to sit with him and the WT
Study conductor to actually grade the "aptitude" of
elders in our congregation to be used in circuit and
district talks at the assemblies and conventions. This
would provide the CO's with a rating and a list of
available and recommended brothers.
It's no stretch of the imagination to see how they could
start expanding this "grading system" to make appointments,
dish out "responsibilities and privileges of service" further.
