KABC-2 Flashcards
What are the age ranges of the KABC-2
3:0-18:11
What theories is the KABC-2 based on?
The Luria Model & Cattel-Horn Carol Theory (CHC)
KABC Background
Cognitive Assessment that evaluates overall intelligence & individual processing skills.
30-70 min administration time
18 subtests
KABC Goals
Measure multiple constructs of intelligence
Facilitate effective neuropsychological assessment of a child’s skills and abilities.
Allows for use with preschoolers
Large and diverse normative sample
KABC Advantages
Reduces ethnic scores differences
Captures the child’s interest with game-like tasks
Blends science & clinical expertise - based on theory.

Upper Extreme: >131
Cattle Horn-Carroll Theory
General intelligence is compromised of several broad and narrow abilities.
Fluid Crystalized Index (FCI) - broad abilities
Short-term memory (Gsm)
Visual Processing (Gv)
Fluid Reasoning (Gf)
Long-term Retrieval (Glr)
Crystalized Ability (Gc)
Luria Model
Mental Processing Index (MPI)
-Sequential Processing
-Simultaneous Processing
-Planning Ability
-Learning Ability
The brain operates in 3 interconnected functional systems
Block 1: Maintain Arousal
Block 2: Codes & stores information
Block 3: Plans & organizes behavior
Luria Model - Block 1
Responsible for Maintaining Arousal and Attention
-mediating attention and concentration
-allowing for a specific focus of attention
-regulating energy level and tone of the cerebral cortex
-recognizing the significance of incoming stimuli
-processing info from the environment
Luria Model - Block 2
Responsible for analyzing, coding, and storing information.
- Integrating incoming sensory info to understand the world and experiences better
-using key senses
-using successive and simultaneous processing
-establishing connections with Block 3
Luria Model - Block 3
Responsible for executive functions: planning, organizing, and programming behavior
-regulating responses to stimuli
-making decisions generating hypotheses, planning and self-monitoring
-mediating complex behaviors
-communicating with other blocks
Luria vs. CHC
FCI includes knowledge (Gc)
CHC is preferred due to the inclusion of Gc and its importance to cognitive functioning
Consider MPI for EL students or those known or suspected of speech/language limitations or autism.
KABC-2 Nonverbal Index (NVI)
Developed to enhance the fairness of the assessment for children with:
-hearing loss or hard of hearing
-very limited English proficiency
-moderate to severe speech impairments or language disorders
KABC-2 Fluid Crystalized Index
The overall FCI scores is made up of scores from the following groups of scale indexes:
Sequential
Simultaneous
Planning
Learning
Knowledge
KABC-2 Mental Processing Index
The MPI score is made up of the following scale indexes:
Sequential
Simultaneous
Learning
Planning
Gsm
core index for FCI and MPI
Sequential (Short-Term Memory)
Number Recall & Word Order
Glr
core index for FCI and MPI
Learning (Long-term storage and retrieval)
Atlantis & Rebus
Gf
core index for FCI and MPI
Planning (Fluid Reasoning)
Story Completion and Pattern Reasoning
Gc
core index for FCI
Knowledge (Crystalized Ability)
Verbal Knowledge and Riddles
Expressive vocabulary
Gv
core index for FCI and MPI
Simultaneous (Visual Processing) - perceiving, storing, manipulating, and thinking with visual patterns.
Conceptual Thinking, Face Recognition, Triangles, Pattern Reasoning, Rover, Block Counting
KABC-2 Subtests

KABC-2 Subtests
Administer after core
Used to explore hypothesis
Used for planned comparison
Can substitute for core if needed
No prescribed sequence, except delayed
KABC-2 Atlantis
Core Subtest - Learning (Glr)
Ages 3-18
Measures: associative memory - the ability to store and efficiently retrieve newly learned or previously learned info.
KABC-2 Conceptual Thinking
Core Subtest - Simultaneous (Gv)
Ages 3-6
Measures visualization, induction and classification.
KABC-2 Face Recognition
Core Subtest - Simultaneous (Gv)
Ages 3 & 4
Measures visual memory
KABC-2 Story Completion
Ages 7-18
Subtest of Planning (Gf)
Measures induction, visualization, general sequential reasoning, general info, and visual analysis.
KABC-2 Number Recall
Ages 4-18
Subtest of Sequential (Gsm)
Measures memory, hearing info, retaining info heard, and using it within a few seconds.
KABC-2 Gestalt Closure
Ages 3-18
Measures closure speed and identification of whole figures from incomplete visual information. Simultaneous and visual processing.
KABC-2 Rover
Ages 6-18
Subtest of simultaneous (Gv)
Measures visual planning, reasoning, and executive functioning
KABC-2 Atlantis Delayed
Ages 5-18
Measures the ability to retrieve newly learned info after a period of time has elapsed. Long-term storage and retrieval of info.
KABC-2 Expressive Vocabulary
Ages 3-6 Core 7-18
Subtest of Knowledge (Gc)
