There is no pattern of test scores which is pathognomonic or even remotely so for Asperger's -- it is a tremendously diverse group psychometrically. Even the DSM-IV-TR's division of "autism" vs. "Asperger's" (AS has no clinically significant language impairment) is increasingly not seen as a valid way to distinguish, and the field is moving towards saying that these really are just different flavors of the same underlying thing (and I agree).
FWIW, let me orient the original poster to the tests mentioned:
> Kaufman Assessment Battery for Children (K-ABC), nonverbal scale.
K-ABC-II is an IQ test (like the WISC-IV, SB-5, DAS-II, etc). However, there is no full-scale score reported here -- the nonverbal subscale is built from I think five (I could walk in the other room and check if anyone cares deeply) of the subtests that have visual stimuli and mostly nonverbal or low-verbal responses (note that the whole concept of the "nonverbal" test is a lot more complicated than most people think it is).
> Peabody Picture Vocabulary Test - III (PPVT-III)
This is *not* an IQ test (per other poster's response). It is a test of receptive vocabulary, which is often highly correlated with overall IQ, particularly in younger kids. Shows pictures, you hear a word and you choose the picture that goes with the word.
> Comprehensive Assessment of Spoken Language (CASL)
> Sentence Completion
> Paragraph Comprehension
> Antonyms
CASL is what you might think it is -- an oral language test battery, of which three subtests were given. Sentence completion -- I read a sentence and you fill in a word at the end, using proper syntax. Paragraph comp -- I read a paragraph and you answer questions about it. Antonyms -- I give you a word and you tell me one that means the opposite.
> Structured Photographic Expressive Language Test - Preschool 2(SPELT-P2)
I'm not familiar with this one, sorry.
>Expressive Vocabulary Test (EVT)
I show you pictures and ask you to tell me the words for things. It's seen as a counterpart to the PPVT, which is receptive.
>Bankson-Bernthal Test of Phonology (BBTOP) word inventory
I'm not familiar with this one either, sounds very SLP-ish.
