The Kaufman Assessment Battery for Children – Second Edition (KABC-2) is an individually
administered measure of the processing and cognitive abilities of children aged three through eighteen. It
measures a range of abilities including sequential and simultaneous processing, learning, reasoning, and
crystallized knowledge to help identify patterns of strengths and weaknesses relevant to educational
outcomes.
KABC-2 subtests are grouped into 4 or 5 scales, depending on the age of the child being assessed; these
scales correspond to processing areas and broad abilities from two theoretical frameworks of cognition.
Subtest scores are reported as scaled scores with a mean of 10 and a standard deviation of 3 (Mean = 10,
SD = 3). For scaled scores, the Average Range is considered to be between 8 and 12. Scores on scales and
global scales are referred to as indexes; these are expressed as standard scores with a mean of 100 and
standard deviation of 15 (Mean = 100, SD = 15), with the Average Range corresponding to 90 through
109.

Subtest Descriptions (by Index):
Knowledge Index/Comprehension Knowledge (Gc)
Expressive Vocabulary: demonstrating acquired general knowledge using a selection of picture
cues
Riddles: identifying words when given oral description or explanation
Sequential Processing Index/Working Memory (Gsm)
Number Recall: recalling a series of digits presented orally, only once
Word Order: identifying pictures in specified order using visual cues
Simultaneous Processing Index/Visual Processing (Gv) – Fluid Reasoning (Gf)
Conceptual Thinking: measures classification ability by selecting one picture from a group that
does not fit or share commonalities with the others
Triangles: constructing pictured designs using a set of bi-colored foam triangles
Pattern Reasoning: completing visual patterns of geometric shapes, objects, or designs
Learning Index/Long-Term Storage & Retrieval (Glr)
Atlantis: learning and recalling names of pictures within a visual field
Rebus: learning and recalling names of designs presented in meaningful sequence
