Google recently began offering a Google Analytics IQ Test to allow individuals to earn certification (good for 18 months) for their skills. The online course is free, but the certification test itself is $50. Earlier today I took (and passed) the test.
If you plan on taking this test, I highly recommend going through the Conversion University tutorials before taking the test, which was much harder than I expected. Even if you don’t want to take the test, the quality of the information contained in the tutorials merit watching/listening to them.
