PPVT is an IQ test - I administered those for a research project I was part of in college. The PPVT doesn't require much training to administer - I think I got about 5 minutes of instruction of the "start at the beginning and continue until there are X errors in Y items" type. It's also very quick to administer. I was working with 2 and 3yos, and it took under 5 minutes per kid. What you got was an IQ score, not a raw score.
I don't have any experience with the other tests. GooglePsychometrist says the K-ABC is a weird amalgam of IQ and achievement, and leads me to believe that the remainder are speech-related, and not intended to be IQ-like.
