How about 3M? 3M = “Minnesota Mining and Manufacturing” gives 14. I note upon Googling, that 3M apparently also stands for “Maintenance and Material Management” = 14.3.
Maybe we should make connecting words count for the shortest acronym contest, but not the longest?
PS. F=Fahrenheit scores 10 and passes the google test. I find this amusing for some reason, despite there being higher scores above.
Here’s one that ties ITU
SAO (Smithsonian Astrophysical Observatory) = 11.6_
Hmm… searching Google for ‘F’ doesn’t seem to run up fahrenheit.
However, the top link on the page gives us a link for the stock quotes for ‘Ford Motor Company’ with F as the symbol.
Which gives us 16! 
Found on this site of U.S. government acronyms:
INL: Bureau for International Narcotics and Law Enforcement Affairs (score: 18.33)
OES: Bureau of Oceans and International Environmental and Scientific Affairs (score: 21!)
-P
Actually what I did wrong is count the letters in “American Antiquarian Booksellers’ Association” before realizing I had the name wrong.
By the way, I had a brainstorm and looked for an international group. Unfortunately they are the ILAB, the International League of Antiquarian Booksellers. That’s still only a 10.25.
NOAA = National Oceanographic and Atmospheric Administration = 11.5 Not bad for four letters.
The ones like 3M and 3C seem to violate the spirit of the question. Keeping a one-to-one relationship between acronym and words, I found
IBO (International Baccalaureate Organization) = 12.6_
:smack: :smack: :smack: :smack: I thought he said to search for ‘f acronym’ not just ‘f’, to allow acronyms that happen to coincide with common words. Sorry, never mind.
Even better, and I’m surprised I’m the first for this one
ISO - International Organization for Standardization = 13.3…
BT (British Telecommunications) = 12.5. Just short… maybe “Telecommunications” is the key to finding a bigger one…
Good idea r_k. How about
MTI MOBILEPHONE TELECOMMUNICATIONS INTERNATIONAL = 14
The only problem is that it doesn’t seem to pass the google test.
OTIA (Office of Telecommunications and Information Applications) = 11.75, even under the strictest rules.
IMTC (International Multimedia Telecommunications Consortium) = 12.75
Or how about the Leatherstocking Telecommunications Consortium (LTC), for a whopping 14.33?
Oh okay, that one doesn’t pass the Google test either. But that’s a silly test.
I agree it’s not a good test, as the acronyms of companies and organizations usually don’t pass it. For another high scoring one, there’s
CTO Commonwealth Telecommunications Organisation = 14
I wonder if, during the days of apartheid, there was a Bophuthatswanan Pneumonoultramicroscopicsilicovolcanoconiosis Association (BPA), for a score of 23.66 
I like that BPA, but change Association to Organization to make it 24 even.
A better 4-letter one is
ITSO International Telecommunications Satellite Organization = 13
So … did the antidisestablishmentarianists have a society?
Or a need for telecommunications?
What we need is an Organization that deals in Antiquarian International Telecommunications (telegraph cables?).
I proposed the Google test, because it seemed like an easy way to agree on the validity of an acronym. Just posting a link seemed inadequate, since I could claim SSQ (29) for
supercalifragilisticexpialidocious supercalifragilisticexpialidocious quantidebiggulation
and simply create a web page that claims this is an acronym.
Of course, now I realize Google is probably not an ideal test, since it changes over time. After a while, googling “ssq acronym” probably will return this link, making it valid. To the critics, please suggest a better test.
